(Exploration, Development, Reclamation, etc.)

This is a fresh Mining Plan, and being submitted for approval, hence review of earlier

proposal does not arise.

6.0 GEOLOGY AND EXPLORATION

6.1 Estimated mineral resources in last approved Mining plan/ scheme of mining documents:

This is a fresh Mining Plan, and being submitted for approval, hence resources of earlier

approved Mining Plan does not arise.

6.2 Depletion / Production of mineral in last five years period from ………. to ……..

Since, the mining operation is not started, hence no depletion in earlier approved quantity.

6.3 Balance estimated mineral (6.1 minus 6.2):

This is a fresh Mining Plan, and the reserves and resources of limestone have been estimated

fresh.

6.4 Briefly describe the topography, drainage pattern, vegetation, climate, rainfall data of the

area applied/ mining lease area.

6.4.1 Physiography: The topography of the area is almost a flat having gentle slope towards

northern direction. The maximum contour level is 242 mRL near the southern boundary and

minimum is 236 mRL near the northern boundary.

6.4.2 Drainage Pattern: The Shivnath River flows from north to south and suddenly takes turn

near the northern boundary of the existing lease of the company which is about 1.5 km from

this lease area and flows towards ESE direction.

The River Shivnath and its tributaries viz Khorsi Nala and Jamuniya nala control drainage of

the area. Various streams originate from this and forms a network to join this nala, which

finally flows in SW-NE direction and meets the river Shivnath exhibiting dendritic pattern in

the most of the area. Beloda branch of the Mahanadi canal enters the area from SSW part of

the lease area and passes towards northern part distributing water to the villages in its

course. All the seasonal nalas flow into the Shivnath River.




13



6.4.3 Vegetation: The common species in nearby villages are Babool, Neem, Pipal, Bargad, Imli,

Amla, Gulmohar, etc.

6.4.4 Climate: The area has sub-tropical climate. May is the hottest part of the year with

temperature reaching upto 470C; while the usual temperature ranges between 27

0C and

420C. January is the peak winter with temperature varying between 28

0C and 13

0C.

Rainfall: The average annual rainfall ranging from 800 to 900 mm. The rainy season starts

from June to September with maximum rain fall in the month of August. Sometimes

intermittent showers accompanied by storm are experienced in March and April before the

on-set of monsoon.

The ground water-level monitored around the area was found to be in the range of 30 - 35

m, which corroborates from the finding of adjacent existing operation. The limestone is hard,

compact and massive in nature and devoid of any secondary porosity like joint, fissures etc

and to have potential ground water occurrence. Adjacent mining operation has reached upto

a depth of 32 m and ground water has not yet encountered.

6.5 Regional Geology: Brief description of Regional Geology with reference to location of

lessee/ applied area.

The limestone and associated formation which is occurring near the village a part of

Chhattisgarh Synclinorium and belonging to Chandi Formation of the Raipur Group of

Chhattisgarh Supergroup. The limestone deposit is almost horizontally bedded with local dip

from 20 to 5

0 towards north. The general strike of the limestone bed is east-west. The

interacratonic Chhattisgarh Basin is crescent shaped and covers about 33,000 sq km area in

almost the center of Chhattisgarh and adjoining parts of Orissa. The basin has a maximum

length of about 300 km along ENE-WSW direction. The maximum thickness of sediments is

estimated to more than 2 km and is epicontinental or stable shelf type.

6.6 Local Geology: Detailed description of geology of the lease area such as shape and size of

the mineral/ ore deposit, disposition variation various litho-units indicating structural

features if any etc.

Generally grey limestone are found on the northern part of the area followed by purple grey

limestone and purple shale successively towards south and similarly the same sequence has

been confirmed from borehole drilled during exploration. Thickness of limestone increases

from SE towards NW direction in the direction of dip. The deposit is structurally undisturbed

since having basin deposition. The local succession of the area is as under:

Soil (alluvial)

Dolomite

Grey Limestone Chandi Limestone formation

Purple - Grey Limestone

Purple Limestone

Purple Shale Gunderdehi Shale

Major portion of the area is covered by lateritic soil with grayish clayey/sandy soil at some

places with an average thickness of 1 m.

Limestone is extremely fine grained, anhedral and occurs as massive, hard compact body.

Colour of limestone generally has a close relationship with quality. It is observed that the

grey limestone have higher CaO content and less MgO content than the underlying purple

limestone which has the intercalation of purple shale in depth.

6.8 Details of prospecting/ exploration already carried out:

The area covers under Prospecting license of 92.165 Ha and 21.959 Ha areas, and the area

applied for ML was 25.019 Ha, but during the recommendation for mining lease, the area has

been reduced to 19.219 Ha.

(Copy of the Prospecting Report is enclosed as Annexure No X).

A systematic geological investigation over the recommended lease area was conducted by

LIPL. The geological investigations include topographic survey, geological mapping, diamond

core drilling and surface sample analyses.

Subsequent to the grant of the PL, LIPL formulated an exploration program for the PL area.

The execution of the exploration campaign was carried out under supervision of LIPL. The

exploration activities were carried out in two different phases in the years 2002-2003 and

2006, respectively.

Initially, a thorough reconnaissance of the PL area was carried out, in order to assess the

potential area to start with the prospecting operations and exploration restricted within

recommended ML potential limestone-bearing area with no mining constraints. As stated

earlier, the entire area is concealed beneath soil cover, hence the lithologies exposed in dug

wells/ dug pits formed the basis for borehole planning and subsequent exploration activities.

Total of 9 vertical core boreholes were drilled with a total meterage of 270 m in the applied

lease area. The summary of exploration activities carried out by LIPL during geological

exploration campaign is given in the table below:

Exploration Activity Quantum of work

6.8.3 Details of samples analysis.

A total of 142 nos. of borehole samples were collected for analyses of 8 radicals (CaO, MgO,

SiO2, Al2O3, Fe2O3, Na2O, K2O and LOI.

Core samples recovered from the boreholes were preserved systematically in wooden core boxes

during 2006, the entire cores of a particular borehole were splitted longitudinally into two halves.

One half was sampled and sent for chemical analysis and the other half of the cores were kept

with appropriate marking. Two meter length of homogeneous core was considered for

preparation of sample unless there was a change in lithological characteristics.

Proper sampling equipment (PW 4400 AXIOF- XRF) was used to ascertain iron-free milling

and pulverization subsequent to chipping by jaw crusher. Two sets of powdered samples

were prepared from the split–half core by standard method of coning and quartering and

sieving to 100 mesh powder. The standard practice of levelling envelopes was followed. One

set of sample was utilized for conducting chemical analysis and the other set was preserved

for future reference. The sampling was done by LIPL’s expert.

6.8.4 Expenditure incurred in various prospecting operations.

LIPL has invested an amount of Rs. 1.04 Crores for systematic and scientific exploration of all

the 5 nos. of sanctioned PL areas, submitted Mining Plan is part of one of the sanctioned PL.

6.9 Method of mineral resource estimation (surface area method, cross section area method

or software method).

6.9.1 Parameters for reserve estimation: Reserves and Resources as per UNFC with respect to

the threshold value notified by IBM may be furnished in a tabular form as give below: (area

explored under different level of exploration may be marked on the geological plan and

UNFC code for area considered for different categories of reserves/ resources estimation

may also be marked on geological cross-sections).

Submit a feasibility/ pre-feasibility study report along with financial analysis for economic

viability of the deposit as specified under the UNFC field guidelines may be incorporated.

The reserves and resources of limestone has been estimated as per the UNFC guidelines by

cross-sectional method. In consideration of the intensity of exploration carried out, the

geological/ structural setup of the deposit and configuration of concession area clubbed with

a number of constraints, estimation of limestone resources on the basis of geological cross

sectional method has been adopted for limestone resource estimation. The cross sectional

area was multiplied by 150 m, considering 75 m aerial extent on either side of the section

line on north south. The quantity of overburden and rejects to be mined along with

limestone has also been calculated by cross sectional method.

The cross sections have been drawn along the section lines trending East-West on drilling

grid and attitude of beds. In order to know the lateral and depth wise extent of

mineralization, the lateral limits of mineralization on the cross sections have been marked on

the basis of correlation with subsurface geology based on structural disposition and chemical

analysis of core samples generated during drilling.

The parameters considered for reserve estimation are as under:

i) The total applied lease area is 19.219 Ha.

ii) Mapping: The lease area has been surveyed by Total Station and preparing detailed

topographical-cum-geological map including all surface geological features, extent of

deposit, structural features, location of bore-holes and the assay-plan has been prepared on

1 : 1,000 scale with contour interval of 1 m, accordingly the Surface Plan has been prepared.

iii) The grid along with temporary survey station points have been marked on the maps.

iv) The general surface level of the area is 239 mRL, maximum surface level of the area is 242

mRL and minimum is 236 mRL.

v) A total 9 vertical core bore-holes were drilled in the area, at 150 x 150 m grid interval.

vi) The reserve has been estimated by cross-sectional method. The limestone bearing areas

have been estimated by cross-sectional method and its influence area.

vii) The depth continuity of mineralization has been considered limited to the depth upto

which direct evidence on mineralization is established through the boreholes.

viii)The quality requirement of limestone for Cement Plan is under:

CaO% 42 ± 2

MgO% 3± 1

SiO2% 10± 2

ix) Limestone occurring in this area has been divided into three different categories so that

the required feed to the cement plant is achieved by proper blending, to achieve the

required quality obtained on day to day basis.

Classification CaO % MgO%

Cement grade limestone (CGL) + 42 Max 4

Blendable limestone (BLST) 38 – 42 Max 4

Sub-grade limestone (SUB) 34 - 38 Max 4

x) The bulk density of limestone has been considered as 2.5.

xi) The recovery of limestone has been considered as 90%.

xii) The area covered under 150 x 150 m grid exploration has been considered under

6.9.7 Economical axis details as per UNFC:

a) The deposit has been explored in a square grid of 150 m and reserve has been

established under proven category.

b) The mine will be a captive mine and catering to the need of limestone to plant for

manufacturing cement on a constant basis since inception. For mining the limestone from

captive quarry in a systematic manner an approved mining plan, subsequently reviewed

through schemes has been in place.

c) The reserve established meets the threshold of manufacturing the cement as prescribed

under NCCBM Norms.

d) On the basis of the detailed exploration (G-1) done over the entire lease area, Mining Plan

has been prepared, having enough experience specific and end use grade of reserves and

specific knowledge of forest/non-forest and other land use data, the economic viability of

the mining project has been proved beyond doubt and thus the mineable part of the mineral

resources which fall under the Ultimate Pit Limit (UPL) and is above the threshold value and

as bifurcated correspond to the Economic Axis (E-1) and the remaining resources as

bifurcated above falling outside UPL that is falling within the statutory barrier correspond to

the Economic Axis (E-2).

e) As per the Pre-Feasibility Study done, cost of limestone production will be ` 250/- which is

comparable being incurred by existing cement plants in the region which being operated

probability in the region. Hence, operating the mining lease is economically viable.

Thus, considering the entire above points/aspects as per the Guideline issued by Govt. of

India, Ministry of Mines, Indian Bureau of Mines, the Feasibility Axis is comes considered as

E-1.

Anticipated Life: The mineable reserves of limestone is 31,99,536 tonnes (say 3.199 million

tonnes) and proposed maximum production rate is about 1.5 lakh tonnes per annum. But,

during the first five years the tentative proposed will be 4,06,350 T and thereafter annual

production rate will be 1.5 lakh TPA will continue, thus, the anticipated life of the mine will

be (31,99,536 – 4,06,350 = 27,93,186/1,50,000 =18.62) about 23.62 years or say 24 years

including first five years.

The life of the mine will likely be increased after the proposed exploration is completed.

7.0 MINING

7.1 A. OPEN CAST MINING

a) Briefly describe the existing as well as proposed method for excavation with all design

parameters indicating on plans/ sections.

The company is having cement plant of 3.5 MTPA clinker capacity in village Sonadih, for this

5.5 million tonnes of limestone will be required, this mine will fulfill a part of the

requirement.

There will be four limestone mines of the company in this area and the production rate of

limestone will depend upon production of limestone from all the mines of the company.

The mine will be designed and the deposit will be exploited with minimum damage to

environment and optimum utilization of limestone for captive use in the Cement Plant.

The salient features of mine design will be as under:

(i) The overburden is in the form of top soil cover, murrum, yellow soil and clayey material

of variable thickness. The overburden will be removed by dozer, and loaded by excavator

into dumpers and transported to the temporary stock yard and will be utilized for plantation.

(ii) The surface level varies from 242 – 236 m. Therefore, from mining point of view, a level

of 239 m has been taken for making the lower benches of 5 m each and, the accordingly the

bench-wise production will be taken up.




35



(iii) The working will be carried out in 2 shifts with staggered roaster manpower deployment

in 350 days in a year.

(iv) Limestone is bedded deposit, massive & compact in nature, hence, the ultimate pit slope

of 500 will be quite stable. For a bench of 5 m height, floor width of 3.5 m will be maintained.

Presently, the working width will be maintained at about 20 m.

(v) The rain-water and seepage water collected in the pit will be stored in the lower benches

and will be used for spraying on the haul-roads and for plantation.

(vi) The floor of the working faces will be kept slightly sloping to facilitate flow of water

towards the sump during the rainy season to keep the working faces dry.

(vii) For blasting, 104 mm dia and 8 m (+0.5 m perihole) will be drilled with compressed-air-

operated wagon drills. The blasting will be done by ANFO/SME/Slurry as column charge and

slurry /cast booster explosive as booster charge. Controlled blasting will be practiced by

using Nonel detonators.

(viii) Hydraulic rock breaker will be used for breaking oversized boulders in place of

secondary blasting.

(ix) Hydraulic excavator of 3.5 cum capacity will be used in combination with 35 tonner

dumpers for loading and transportation of limestone.

(x) The limestone ROM will be directly transported to the cement plant after crushing and

screening (if required).

(xi) The haul distance from mine site to crusher is about 3 to 5 km.




36



(xii)For the purpose of grade control, samples will be drawn from each blast/blast holes and

will be analysed for its grade.

(xiii) The requirement for making clinker, the average chemical composition of limestone

should be maintained is as under:

CaO% 42 ± 2

MgO% 3± 1

SiO2% 10± 2

(xiv) The limestone occurring in this area has been divided into four different categories so

that the required feed to the cement plant is achieved by proper blending at the crushing

plant, so that the graded quality is achieved on day to day basis.


Cement grade limestone (CGL) +42 Max 4



(xv)The sub-grade of limestone produced from the mine will be separately stacked and

processed by suitably blending as per requirement. The blending ratio will vary according to

parameters of raw mix from time to time.

(xvi) The Staker – Reclaimer and Raw-Mills operations will be governed by Production and

Quality Control department of the Cement Plant, which will also co-ordinate with Mine

Management to dispatch particular quality of crushed limestone as may be required, so that

the Raw-Mix design suits the required parameters i.e. LSF, SM and AM, etc.




37



(xvii) All efforts will be made considering eco-friendly mining in the area. For this, dense

plantation will be done all around the lease area in the non-mining zone to improve aesthetic

beauty and for development of green belt.

(xviii) The mining loss during the mining of limestone is expected as about 10% of the total

ROM due to intercalations, fractures, clay pockets, voids, cavities, etc.

(xix) Out of this, 5% will be considered as waste/intercalations and kept separately and

remaining 5% will be due to voids and cavities. This will be temporary stocked within the

lease area and utilized for road maintenance from time to time.

7.17 Describe briefly the layout of mine workings, pit road layout of faces and sites for

disposal of overburden/ waste alongwith ground preparation prior to disposal of waste,

reject etc. A reference to the plans and sections may be given. UPL or ultimate size of pit is

to be shown for identification of the suitable dumping.

(i) Bench Height – The top bench will have a floor level of 239 mRL with variable height,

thereafter, the bench height of 5.0 m will be maintained, which is suitable for 3.5 cu m

bucket capacity excavator. The soil/OB available over the deposit will be scraped with dozer.

(ii)Bench Width – For a bench of 5 m, working width of 12 m will be required to

accommodate for easy movement of HEMM equipments, dumpers and blasted material. As

per MMR & Circulars of DGMS, the width of the benches should not be less than:

(a) Width of the widest machine playing on the bench plus 2 m extra.

OR

(b) If the dumpers ply on the bench, 3 time the width of the dumpers.

OR

(c)Not less than the height of the bench.

(iii) Bench Alignment – In this area, the grade variation is along the strike, therefore, it has

been decided to open the benches along the strike-direction for production of all grades of

limestone, so that suitable blending can be done as required.

(iv) Face length – The face length is selected in such a way that it could produce desired

quality of limestone without any interruption. Thus, the planning of designed pit, the face

length of exposed limestone will be more than 100 m for each bench. Two faces will be

maintained for proper deployment of machineries for day to day grade control.

(v)Road – (a) An adequate net work of roads will be maintained for transportation of

limestone from face to crusher site. For free movement of vehicles (dumpers), it is proposed

to have one way traffic on all haul roads.




51



(b) For two-way traffic, the haul roads will be preferably be at least 3 times, plus 5 meters,

the width of dumpers, thus the width of the road will be maintained at 17 m.

(c) As per statute, the gradient of ramps should not exceed 1 : 16. In this planning, all ramps

have been designed with a gradient of 1 : 20, however, a small stretch of 10 m length after

the ramp will be kept level for easy movement of dumpers before another ramp starts to join

the next bench below.

(d) A minimum turning radius of 10 m on inner side is proposed for roads at turning points.

Adequate super elevation will be provided at the curves for safe turning of dumpers.

(e) All the haul roads will be constructed with water bound macadam and water spraying will

7.18 Conceptual Mine Planning upto the end of lease period taking into consideration the

present available reserves and resources describing the excavation, recovery of ROM,

Disposal of waste, backfilling of voids, reclamation and rehabilitation showing on a plan

with few relevant sections.

The mineable reserves of limestone is 31,99,536 tonnes (say 3.199 million tonnes) and

proposed maximum production rate is about 1.5 lakh tonnes per annum. The anticipated life

of the mine will be about 24 years.

The life of the mine will likely be increased after the proposed exploration is completed.

7.19 Exploration programme: After the completion of proposed borehole during the first year,

the deposit will be fully explored and hence no need for further exploration.

7.20 Excavation: Presently, the area is virgin land.

During the first five years, about 3.15 Ha area will be developed as working pit upto a level of

228 mRL.

Land use for per five years breakup upto 20 years.

7.25 Afforestation:

During the plan period, about 1.85 Ha area will be covered by plantation, @ 2,000 saplings

per hectares. Karanj, Khamar, Akesia, Gulmohar, Sal, Mango, Jamun, Amrud, etc, are the

common species which are planted.

During the first five years, entire available area within the 7.5 m of barrier zone will be

covered by plantation. Thereafter, only maintenance will be carried out.

7.26 Reclamation and Rehabilitation:

Land degradation is one of the major adverse impacts of open-cast mining activities and any

effort to control adverse impacts would be incomplete without appropriate land reclamation

strategy. After the exhaustion of entire mineable limestone, part of mined out pit will be

backfilled by generated OB/waste and remaining mined out pit will be converted in to water

tank for utilization in for irrigation purpose. The water reservoir will be properly fenced by

barbed wire or a bund will be constructed outside the water reservoir during the closure of

the mine.

8.0 UNDERGROUND MINING

The entire working is being carried out by opencast mechanized method and this will

continue in future, hence underground working will not be required.

* * * * *




57



9.0 MINE DRAINAGE

a) Minimum and maximum depth of water table based on observations from nearby wells

and water bodies.

The ground water level monitored around the applied area was found to be in the range of

30 - 35 m, which corroborates from the finding of adjacent existing mines. The limestone is

hard, compact and massive in nature and devoid of any secondary porosity like joint, fissures

etc. to have potential ground water occurrence. Adjacent mining operation has reached up

to a depth of 32 m and ground water has not yet encountered.

b) Indicate maximum and minimum depth of working.

During the first five years, the workings are expected to be done up to average 11 m depth

from surface level which is above from the water table.

c) Quantity and quality of water likely to be encountered, the pumping arrangement and

places where the mine water id finally proposed to be discharge.

Regionally in the area, the source of surface water is Shivnath River. The HFL of the Shivnath

River is 237 mRL. The River is about 1.5 km from the northern part of the lease area, Hence,

there will be no encroachment of surface water in the mine.

The rain water accumulated during the rainy season will be pumped out through proper

arrangement of water pumps.

d) Describe regional and local drainage pattern. Also indicate annual rain fall, catchments

area, and likely quantity of rain water to flow through the lease area, arrangement for

arresting solid wash off etc.

The Shivnath River flows from north to south and suddenly takes turn near the northern

boundary of the existing lease of the company which is about 1.5 km from this applied lease

area and flows towards ESE direction.




58



The River Shivnath and its tributaries viz Khorsi Nala and Jamuniya nala control drainage of

the area. Various streams originate from this and forms a network to join this nala, which

finally flows in SW-NE direction and meets the river Shivnath exhibiting dendritic pattern in

the most of the area. Beloda branch of the Mahanadi canal enters the area from SSW part of

the lease area and passes towards northern part distributing water to the villages in its

course. All the seasonal nalas flow into the Shivnath River.

In the lease area, the terrain is almost flat with gentle slope towards northern direction,

almost the entire lease area is covered with soil and limestone is out cropping at few places.

The mining by opencast method will be worked throughout the year and hence effective

arrangements for drainage during entire year for seepage water and rain water, hence

provisions for adequate dewatering arrangements in the mining pits so as to keep the

working floor free from water accumulation.

In open cast pit, water reaches the working faces due to following reasons.

(i) From surface run off rain water, sub-surface and seepage.

(ii) By direct precipitation over workings during rainy season.

These can be controlled by:

(i) Preventing surface run-off water from entering the active working pit. The water should

either be diverted to temporarily standby/unused pit to serve as a water reservoir.

(ii)Pumping of percolated and direct precipitated water from the pit to temporarily un-used

pit/low lying area of the pit as a water conservation measure and to use it for dust

suppression and plantation.

Annual Rain fall:

The average annual rain-fall in the area is about 900 mm which comes to be 22.5 mm/day

considering 40 rainy days in a year. For calculating pump capacity, it has been assumed that




59



the average quantity of rain water collected in the pit during one day will be handled during

the same day within 8 hours.

Pumping load:

The mine workings are proposed up to 30 m depth and up to end of life of mine. The mine

benches will be aligned in such a manner that water always flows down to bottom most

point and the main workings remain dry. The daily pumping load has been calculated from

the approximate catchment area from which the water is likely to flow into the pit. The

working’s are proposed in 3.15 Ha during the first five years planning. Therefore in the

planning the catchment area has been considered 50 percent more than the area proposed

to be used in mining in this planning, which comes to about 1.575 Ha or 15,575 sqm.

Catchment Area = 15,757 sqm

Pumping Load/day = 70,850 x 0.03 = 473 cum

Hourly Load/day (8 hr. working) = 3,784 or say 3,800 cum

Pumping capacity:

The hourly pumping load has been calculated 3,800 cum. Therefore one pump of 5 HP

capacity with 50 m head will be installed and one additional will be kept standby.

Sump:

A sump of 20 m x 20 m and 3 m deep will be made at suitable lower most point at the

bottom bench for storage of precipitated water and installation of pump.

11.0 USE OF MINERAL AND MINERAL REJECT

11.1 Describe briefly the requirement of end-use industry specifically in terms of physical and

chemical composition.

The entire limestone mined out from this mine will be utilized in the lessee’s Cement Plant

and this will be captive mine for the Plant which is installed about 2 km from the mine.

11.2 Give brief requirement of intermediate industries involved in up-gradation of mineral

before its end-use.

No intermediate industry will involve for up-gradation of limestone, only suitable blending of

different-grade mineral will be carried out on the crushing unit at the plant site.

11.3 Give detail requirements for other industries, captive consumption, export, associated

industrial use etc.

The entire produced limestone will be captive consumption in the lessee’s Cement Plant.

11.4 Indicate precise physical and chemical specification stipulated by buyers.

The specification of Cement grade limestone has been standardized and accepted all over by

Cement industries. The norms evolved by National council of Cement and Building Materials

are given in the following table:

Oxide components Acceptable range for

manufacture of

clinker

CaO 42 ± 0.5%

MgO 3± 0.5%

SiO29± 0.5%

Al2O3 2.4 % ± 0.4%




63



For determining acceptable range of SiO2, Al2O3 and Fe2O3 in the limestone, the following

factors of modulus values for ultimate raw mix for manufacturing cement has been

considered by the company.

Item Formula Range

Silica modules SiO2

---------------------

Al2O3 + Fe2O3

2.2 ± 2

Alumina Modulus Al2O3

---------------------

Fe2O3

1.6 ± 2

Lime Saturation

Factor (LSF) Cao

--------------------------------------

2.8 SiO2 + 1.2 Al2O3 + 0.67 Fe2O3

1.2 to 1.5

Based on the above criteria, limestone occurring in this mine has been divided into four

different categories so that required feed to the cement plant is achieved by proper blending

at the crushing plant while transportation, so that the graded quality is achieved on day to

day basis.


Cement grade limestone (CGL) 42 – 44 Max 4






64



11.5 Give details of processes adopted to upgrade the ROM to suit the user requirements.

The blending of above different types of limestone will be carried out from time to time as

per daily requirement of Plant.

During this first five years period, blending of high MgO limestone is not required; hence at

that time blending proposal is not anticipated, this may be estimated after this five years

period.

* * * * *

12.0 PROCESSING OF ROM AND MINERAL REJECT

12.1 If processing / beneficiation of the ROM or Mineral Reject is planned to be conducted,

briefly describe nature of processing/ beneficiation. This may indicate size and grade of

feed material and concentrate (finished marketable product), recovery etc.

There is no proposal for mineral beneficiation, only crushing and screening of limestone will

be carried out. A Crushing and screening plan has already installed within the existing mining

lease area of the company. The details ROM will be transported to the C & S plant for further

processing. The details of C&S Plant is as under:

MAKE/SUPPLIER: CIMMCO-KHD, V-Belt Drive

SPECIFICATIONS: Type: Impact Crusher, Feed Size < 1.2 Meter, Output size - <75 mm, Motor:

900 KW, Speed: 350 RPM, Designed Capacity: 650 TPH, Operating Capacity: 900 TPH.

It is envisaged to transport crushed limestone directly to the cement Plant. During mining, if

clay mixed limestone is generated, it is proposed to installed mobile screen inside the pit to

ensure better utilization of the limestone.

12.2 Give a material balance chart with a flow sheet or schematic diagram of the processing

procedure indicating feed, product, recovery, and its grade at each stage of processing.

14.0 PROGRESSIVE MINE CLOSURE PLAN UNDER RULE 23 OF MCDR’1988

14.1 Environment Base line information: Attach a note on the status of baseline information

with regard to the following.

a) Existing Land use Pattern indicating area already degraded due to quarrying / pitting,

dumping, roads, Processing plant, work-shop, township etc.

The applied lease area comes under, private land, Govt. land and forest land (bade jhad ka

jungle), but cultivation in the lease hold area is very limited and most of the land is devoid of

vegetation. The land is still virgin and no mining activity has been done in the area till date.

Summary of the land use is as under (Area in Hectares):

(x) Others (bade Jhad ka Jungle) 16.116 (xi)Pvt. other land Nil

-- -- (xii) Others (specify) Nil

Total 16.116 Total 3.103

(b) Water Regime: Water is the primary requirement of all human beings and their activities.

Information about its availability and quality in the leasehold area and its surrounding is

necessary and important. The water resources in the mining lease hold area and surrounding

may be placed into two major categories –

Surface water resources: In this area river Shivnath is the main surface water source. It flows

from NNW to East direction. It is a major tributary of river Mahanadi. The villagers have




74



generally 2 to 3 kachha (unlined mud) ponds which are used for bathing, clothes washing etc.

These nallahs and ponds are dry except during monsoon period.

Ground water resources: In area confined to mining lease, the limestone is hard, compact

and massive in nature and devoid of any secondary porosity like joints, fissures etc. to have

potential ground water occurrence. However, regionally ground water occurs under water

table to semi- confined and confined conditions. In the shale the weathered / jointed zones

and bedding planes constitute the water table aquifer. In general, the shale is considered as

poor aquifers yielding only small quantities of water in wells. The limestone and dolomite are

the principal aquifers in the area.

Discharged Water: No affluent will be discharged to the river. During rainy season, a garland

bund all along the mining area will be provided to restrict the surface runoff. However water

gets accumulated in pit sump through rain. Pit sump acts as a settlement tank where water

will be allowed to store for adequate time to settle down its entrained solid. Finally clean and

clear water will be discharged to the river through harvesting pit through nala where check

dam is provided to check the siltation to discharge in-to river.

(c) Flora and Fauna: With the operation of plant & mine over a period of two decade

adjoining to the proposed mining lease area, there has been seen changes in the form of

general aesthetic and ecology in the area under the control of LIPL. Initially the area was

witnessing mixed land uses with barren land, double crop, major and minor. There are only

few mahua, sal and Plumb trees and other species scattered over the area and the adjoining

area. No wild life is conspicuous within the area. Rabbits are seen in the nearby area of the

lease. List of flora & fauna authenticated from District Forest Officer is enclosed. Now nearly

6.2 lac trees have been flourishing adjoining to the proposed mining lease area and within

and outside of the present operating mining lease boundary, with the survival rate of 80%.

(d) Quality of air, Ambient Noise level and water: Under the EIA notification as per

environment (Protection) Act 1986, environmental clearance has become a mandatory for

any mining operation. LIPL shall obtain valid clearances before starting mining operation in

the proposed Mining Lease area

Area is predominantly an agricultural land. Within 10 km radius, no industries other than

mining activities and cement plant of LIPL are located. The baseline environment quality

represents the background environmental scenario of various environmental components

such as air, noise, land, water status of the area. To assess the prevailing environment

condition regular air and water samples are taken and analysed by the MoEF approved

agency M/s ANACON LABORATORIES PVT LTD, Nagpur. Outcome of the analysis report is

briefly discussed below:

Air Quality: The sources of emission in the area are mainly the activity of Sonadih cement

plant & mine, vehicular traffic, agricultural fields, unpaved roads and domestic fuel burning.

- 3.5 MTPA dry process and recliner based cement plant

- Present Limestone production from the mines of LIPL of 5.5 MTPA

- Local activities & roads

- Vehicular movement

LIPL has implemented various pollution control systems and maintaining the emissions far

less than those of the prescribed standards at both cement plant and mine area. Water

sprinkling to suppress dust is being carried out in mines.

Identification of Ambient air Quality Monitoring Stations: Ambient air quality of the mining

lease area and within a radius of 10 KM has been assessed through a network of 8 ambient

air quality locations. Of the 8 locations, 3 ambient air quality stations are located in the

buffer zone and 5 stations within lease area in such a way that some of the stations were in

the upwind direction based upon the prevailing conditions at the time of sampling. Few

stations outside the lease area, in downwind direction were selected to ascertain the impact

of mining and associated operations on ambient air quality beyond the mine boundary.

These stations are designed keeping in view of the climatologically conditions of the study

region and mine operations of LIPL.

NOISE ENVIRONMENT: Noise survey was carried out in the existing mining area to measure

the noise produced due to operation of heavy earth moving machineries, Noise level has

been monitored in core and buffer zone to measure the present level and to assess the

impact on the neighboring human settlements. Noise levels were measured near highways,

residential areas and other settlements located within 10 km radius around the mine area.

Noise levels were monitored at 5 Locations near the Mining Lease area. The noise recording

stations in the buffer zone are given in the following table. The day equivalent noise levels

were found to be relative high due to local activities in the villages. Noise levels recorded in

the night time were found to be less than 51 dB (A) which is well within the threshold value

same has been identified for Surface water quality monitoring and water sample has been

taken. Analyzing water samples collected for physico-chemical and biological parameters and

found that the associated parameters are well within the norm stipulated under IS 10500.

(e) Climatic Condition: The Lease area experiences warm temperature climate. The mercury

touches the level of 48º C during summer and goes down to 10 C during winter. Winter lasts

for short period only. The mean wind speed over the last 20 years was ranging from 1 kmph

in December to 15 km/h in June. The relative humidity over the last 20 years range between

34 in May to 87 in August.

(f) Human Settlement: The lease area falls under Balodabazar Tehsil of Balodabazar -

Bhathapara District. Most of the villagers are socially and economically backward. The main

occupation of the villagers is agriculture. Population statistics in above mentioned villages

falling under the vicinity of applied lease area, is collected from National Informatics Centre,

14.2 Impact Assessment: Attach an Environmental Impact Assessment Statement describing

the impact of mining and beneficiation on environment on the following:

EIA basically involves the study of prevailing environmental condition and the effects lay on

the environment due to ongoing mining activities. Existing mining obviously gives rise to

change in topography, marginal change in air quality, slight increase in noise level and may

induce moderate ground vibration. EIA basically deals with the above factor and establish

the relation in the light of existing mining activity. Following paragraphs describes the

impact assessment over the next five year and upto conceptual plan period.

LAND ENVIRONMENT:

The lease area is still virgin and no mining activity has been carried out in the area except

some boreholes drilled during the prospecting. N-W part of the lease is non mineralized area

and will be utilized for reject and waste dump. The measures taken by LIPL are likely to bring

forth positive impact on the landscape, although the degraded land cannot be fully

reclaimed. The aesthetic environment of the area will have a positive impact by the time

mining ceases in the area with proposed thick afforestation. At the end of the next five year

plan and up to end of conceptual plan, the land use pattern with in lease hold area is likely to

be as follows:




81



LANDUSE PATTERN OF THE MINE AREA (Ha.)

Content Land use at the end

of 1st

five year

Land use up to the

conceptual period

A. Area under mining lease 19.219 Ha 19.219 Ha

B. Mineralized area where mining

would be carried out

19.219 Ha 19.219 Ha

C. Quarrying 3.15 Ha 10.05 Ha

D. Dumping of OB waste 1.20 Ha Nil

E. Stacking of top soil 0.50 Ha

F. Haulage road, workshop, mines

office, etc.

1.10 Ha Nil

G. Area for green belt 1.85 Ha 1.85

TOTAL 7.80 Ha 11.90 Ha

IMPACT ON AIR QUALITY:

Air quality will be affected due to total handling of limestone and movements of vehicles.

Various non point sources in mining like drilling, blasting, excavation, haulage over internal

roads, stock pits, loading and unloading etc. produces gaseous pollutants like SPM, SO2, CO

and Nox. By adopting appropriate monitoring and control measures as suggested in

Environment Management Plan pollutants will be well within the safe limit.

IMPACT ON WATER QUALITY:

There would not be any adverse effect on water quality due to mining. There will not be any

effluent discharge to main water course. The HFL of the Shivnath River is located at an RL of

237 m. A series of check dams are proposed for trapping the silt of mines discharge water

during rainy season. The water overflow from the check dam will drain to Shivnath River

through the existing seasonal nala.




82



IMPACTS ON GROUND WATER TABLE:

Detailed hydro geological studies have been carried out in the existing operating mine area

which is adjoin to the proposed mining lease area to know the ground water table and its

interaction with the mining activities. Ground Water levels were monitored by establishing

the observatory wells within 10 km radius of the study area. The ground water levels

monitored around the mine lease area were found to be in the range of 30-35 m.

IMPACT ON WATER QUALITY:

As the mining will progress horizontally and vertically, the rain water precipitating within the

work area shall be stored in the bottom most bench. During mining of the limestone, top

soil/mineral reject will be generated and the same will be disposed off all around the mining

lease boundary for formation of bund all along the boundary.

During monsoon there is some possibility of transportation of the silt and sediments into the

nallas from the mine, thus causing pollution of the natural drainage system. In order to avoid

soil erosion and also the possibility of carryover of the material with rainwater, a retaining

wall with garland drain will be provided. Hence adverse impact on water quality is not

envisaged.

WATER CONSUMPTION AND WASTE WATER GENERATION:

LIPL will use around 50 m3/day of water in the following areas:

1. For water sprinkling on main mine haul roads and feeder roads.

2. For greenbelt development.

WASTE WATER GENERATION:

The wastewater generated from the domestic front is mainly from toilets and canteen. This

water is treated in septic tank followed by Soak pit.




83



IMPACT ON NOISE LEVEL:

Noise will be produced due to drilling, blasting, compressors, pumps, movement of vehicles

and other machinery. The noise generated by the mining activity will be dissipated within a

small zone around the mines. There will not be any major impact of the mining activity in the

vicinity. However, pronounced effect of above noise levels will be felt only near the active

working area and on the personnel working in the vicinity.

The impact of noise on the villages is negligible as the villages are far located from the

applied lease area. LIPL will provide a greenbelt of 15 m width all along the mine lease

boundary.

IMPACT ON VIBRATION LEVEL DUE TO BLASTING:

The lease is located near village Raseda which is located at 0.5 km distance from mine

boundary. Blasting at the lease area will be conducted by adopting the latest technology of

Shock Tube Initiation System which lower down the ground vibration to a great extent and

the same method will be followed in future as well, hence there will be no impact on the

nearby dwellings and structure as well. Therefore there is no danger on account of ground

vibration induced by blasting.

IMPACT ON SOCIO-ECONOMICS:

NO REHABILITATION: The lease area does not cover any habitation. Hence the mining

activity in the area will not involve any displacement of human settlement. The mining

operations will not disturb/relocate any village or need resettlement. Thus no adverse

impact is anticipated.

IMPROVEMENT IN SOCIO ECONOMIC STATUS: The mining activity will improve the

economic status of the people around the applied lease area. Continued mining activities will

benefit the local people due to provision of more infrastructure facilities provided by local




84



industry as mining industry boost the local market, which will invite people from different

places to install their ancillary units. Socio economically the area is typically rural and

backward. The impact of the mining on the socio-economic environment of the nearby

villages will be positive. Take-over of cement plant and mines by Lafarge India (P) Ltd in 1999,

has brought a positive-change in the socio-economic conditions of this region.

To uplift the economic status of this area, LIPL has set up multi dimensional Rural

Development Programme which has helped in building up the overall socio-economic

structure of population of villages adjoining.

The salient features of Rural Development Programme are to provide over the period of next

five years and up to end of conceptual plan:

1. Health and hygiene through mobile medical clinic

2. Agricultural extension

3. Drinking water project

4. Educational programme

5. Woman and youth development activities

6. Income generating schemes

7. Sports and cultural activities

LIPL is keen in welfare of its employees and employees are covered by number of benefit

schemes, which has changed the entire set-up in relation to education, housing, transport,

social features, marketing, recreation, sports etc. where employees and their family are

involved.

LIPL with their cement plant and captive limestone mine have also had their significant

contribution to this all round social and economic growth of the immediate neighborhood.

The company has provided housing, educational and medical facilities and drinking and

running water supply to the employees in the cement plant and mines.




85



The impact on socio-economic environment is found to be positive. The factory is located in

economically backward area in district Baloda Bazaar Bhatapara. Plenty of job opportunities

have been made available to local people which has increased the living standard.

Communication and transport facility has been made available. Management has set up full

fledged township with all facilities of Public school, market, recreation club, health centre,

community hall, guest house, road, street lights, water supply and sewerage system etc.

There by quality and per capita income has improved.

IMPACT ON HISTORICAL MONUMENTS ETC.

No impact as no public buildings, places, monuments etc exist within the applied lease area

or in the vicinity

14.3 Progressive reclamation Plan:

To mitigate the impacts and ameliorate the condition, describe year wise steps proposed

for phased restoration, reclamation of lands already/to be degraded in respect of following

items separately for 5 years period.

14.3.1. Mined-Out Land: Describe the proposals to be implemented for reclamation and

rehabilitation of mined-out land including the manner in which the actual site of the pit

will be restored for future use. The proposals may be supported with yearly plans and

sections depicting yearly progress in the activities for land restoration/

reclamation/rehabilitation, afforestation etc, called “Reclamation Plan”.

Mined out Pit: The mined out pit, after confirming the exhaustion of entire limestone upto

the economic depth will be converted into a water reservoir, and a part of pit will be

backfilled through generated OB/waste.




86



Plantation Programme: During this plan period, the plantation will be carried out on the

southern side in the non-mineralized zone which will be as under:

Year Plantation

V Year 3,700 740

Total 18,500 3,700

A Reclamation Plan has been prepared and enclosed as Plate No. VIII.

14.3.2. Topsoil Management: The topsoil available at the site and its utilization may be

described.

The generated top soil will be temporary stacked along the lease boundary and covered by

plantation.

14.3.3. Tailings Dam Management: The steps to be taken for protection and stability of tailing

dam, stabilization of tailing material and its utilization, periodic desilting measures to

prevent water pollution from tailings etc, arrangement for surplus water overflow along

with detail design, structural stability studies, the embankment seepage loss into the

receiving environment and ground water contaminant if any may be described.

Since there will be no beneficiation plant, the question of tailing dam management does not

arise.




87



14.3.4Acid mine drainage, if any and its mitigative measures.

There is no mineral of such nature hence there is no chance of acid mine drainage, since the

water is potable.

14.3.5. Surface subsidence mitigation measures through backfilling of mine voids or by any

other means and its monitoring mechanism.

Backfilling of mined out pit does not possible, at this stage after the 8th

year mined out pit of

will be backfilled by generated overburden and part of the mined out pit will be converted

into water reservoir.

14.3.6. The information on protective measures for reclamation and rehabilitation works year

wise may be provided as per the following table.

1.0 Introduction

With a view to sustain the present capacity of Sonadih Cement Plant owned by Lafarge India Private Limited at Sonadih in Balodabazar Tehsil of Raipur Distrist in Chhattisgarh state for an adequate period and also to withstand the proposed increased production capacity of 3.5 MTPA of clinker, geological investigation was undertaken under prospecting license held by Lafarge India Private Limited at B,C,D,E,& F Blocks measuring a total of about 508.633 hects covering parts of Sonadih, Kesdabri, Dhabadih and Raseda villages to make quantitative and qualitative assessment of the deposit and establish additional limestone reserve to increase the life of mine to cater smooth raw material supply to the cement plant for a prolonged period. Lafarge was granted the prospecting license over B,C,D,E& F Blocks bearing given reference measuring a total of about 508.633 hects by Govt. of Chhattisgarh prior to undertaking the prospecting activities.

a) B Block- Letter No- 2-126/2001/M dt 24/04/2002 over an area of 86.350 Hects b) C-Block - Letter No- 2-125/2001/12 dt 13 /1/2006 over an area of 92.-165 Hects c) D-Block - Letter No- 2-28/2004/12 dt 25 /1/2006 over an area of 180.-012 Hects d) E-Block - Letter No- 2-38/2002/12 dt 18 /1/2006 over an area of 21.459 Hects e) F-Block - Letter No- 2-80/2003/12 dt 18 /1/2006 over an area of 128.147 Hects

Keeping in view of the above, Lafarge entrusted the job of exploration to M/s.Drilltech Consultant, Kolkata under work order no SCP/O1N95/259056/1/1 dated 5th Jul 2002 and later vide Work Order No.LIPL/CPO-SER/EOO/GEO/SCP/05/5370 dated 18th May 2005 subsequent to which detailed prospecting of the area was undertaken in two field sessions by Topographical Survey, Geological Mapping of the area followed by diamond core drilling, logging of the core samples and preparation of the samples in 100 mesh for chemical analysis. During this exploratory work, the laboratory facility of Sonadih Cement Plant andArasmeta Cement Plant was availed by Lafarge for conducting chemical analysis of all the samples by XRF techniques. All these activities were carried out during the period from August 2002 to March 2003 and later during the period from February 2006 to May 2006. After completion of field work and availability of chemical analysis results from Lafarge, a detailed prospecting report has been prepared comprising of reserve and ROM quality of limestone for all the prospecting licenses held.

After studying the technical and economic feasibility of the prospected area Lafarge management decided to go for mining lease over the abovementioned areas in form of three different ML applications i.e. 464.766 Hect, 71.449 Hects & 25.019 Hects.The Applied ML area under reference includes the following blocks:

1.0.1 Location

The PL area demarcated as Block , falls in the villages of Raseda & Khapri in Tehsil Balodabazar, District Raipur are located at about 100 km NNE of Raipur city and 10 km. from Baloda Bazar Town in the district of Raipur, Chhattisgarh State. However the applied ML area 25.019 ha falls in the village of Khapri only. The nearest railway station Bhatapara, is located at about 35 km. from the PL areas on Mumbai-Howrah main line of South-Eastern Railway. The areas constitute a part of Toposheet No.64K/1 and 64K/2 of Survey of India and are bounded by Longitude 820

820 0 0

Road

The distances from PL area to major areas are as follows:

1. Baloda Bazar (nearest town) : 10 km. 2. Bhatapara (nearest railway station) : 35 km. 3. Nipania (nearest railhead) : 24 km. 4. Raipur (State Capital) : 100 km.

1.0.2 Physiography

The topography of the region is characterized by plain and flat with a gentle slope towards South-West direction. The average elevation is around 237.930 Mtrs above MSL with the maximum being around 240.240 M. While most of the areas are under a cover of lateritic soil the other parts are outcropping. The present land use being

and government and private land in the revenue records, however the PL areas are practically devoid of any forest with occasional existence of big trees and has some sparsely distributed vegetation comprising ofAcacia arebacia trees and wild berry.

1.0.3 Climate

5

The area has sub-tropical climate with average annual rainfall in the range of 80 to 90.00cm. The rainy season persists from June to September with maximum rain fall in the month of August. Sometimes intermittent showers accompanied by storm are experienced in March and April before the on-set of monsoon. May is the hottest part of the year with temperature going upto 470C while the usual temperature ranges between 270C and 420C. January is the peak winter with temperature varying between 280C and 130C.

Water table is very near to the surface particularly during monsoon (1.0m depth in most places) gradually going down to 6.5m below surface during hot summer.

1.0.4 Scope of Work

The scheme for the geological investigation was suitably framed to demarcate the potential area of cement grade limestone and estimation of mineable reserve along with its quality. The scope of work broadly included:

Topographical Survey in 1:2000 scale with 1.0 m contour interval of the individual PL blocks with grid lines at 150 metre interval through N-S & E-W direction and determination of grid levels taking reference coordinate (3000,3000) from borehole 11/86 of Block-A. Geological mapping in 1:2000 scale along with surface sampling Diamond Core Drilling (270 metres in 9 boreholes) in the Applied ML Area i) C north & E middle Block : 09 No. of boreholes Geological logging of all the boreholes and sampling of the cores.

Chemical analysis of all the samples were conducted at the laboratory of Arasmeta and Sonadih Cement Plant by XRF.

2.0 Regional Geology

The area forms a part of Central Indian Peninsular Shield of which the oldest rock formations encountered are the schists and gneisses of Archean age. The other formations found in the district are of Proterozoics and Carboniferous limestone, sandstone, coal seams and the laterite etc.

2.0.1 CHATTISGARH BASIN:

The crescent shaped Chattishgarh basin covers an area of about 33,000km2 in the central India craton, and lies mostly in the southeastern part of Madhya Pradesh, with marginal extensions into Orissa.

Ball (1877) and King (1885) described the Geology of the Chattishgarh basin on the basis of regional traverses, and considered the Chattishgarh sediments as equivalents of the Vindhyan. Dutt (1964) carried out traverse mapping in the southern part of the

Schniner (1969,1971) made a valuable contribution to the stratigraphy of the Northeastern part of the Chattishgargh Basin. He established the cyclic nature of the sedimentation and identified each cycle by a local geographic name.

Ghosh and Shah (1965), Sen (1966), Chanda and Bhattacharya (1973) and Jairaman and Banerjee (1978) studied the stromatolites of the Raipur Limestone. Kreuzer et al. (1977) carried out geochronological studies of the Chandarpur group. Verma et al (1977) carried out the Palaeomagnetic studies on the Gundertdehi Shale.

2.0.2 GEOLOGICAL SET-UP

The Chattisgarh sediments rest unconformably on the basement of Archiean granites and Gneisses with associated metavolcanic metasedimentery belts known locally as Chilpi and Sonakhan Groups. In the eastern part of the basin in the Raigarh area, outliers of Gondowana formations are noticed from Amaldiha to Kantahardi, around Tundri and Bendhrojharia. The Gondowana is represented by Talchir conglomerate and sandstone and Barakar sandstone. The Basin shows evidences of structural disturbances along the eastern, northern and western margins. In the eastern part of the basin, the sediments are intensely folded and faulted especially in the Barapahar area. Northwest of Saragarh, a dome is noticed in the sediments around Siroli Dongar. Along the northern margin, which trends E-W, evidences of disturbances are noticed at a number of places. Near Kharsia, the hill range exposes Chandarpur sandstone, which is a partially faulted dome. The western margin of the basin is faulted against Chipli Group of metavolcanics and metasediments and granites. The southern and southeastern margins of the basin do not show any signs of disturbance. In the central part, gentle rolling dips are noticed.

2.0.3 LITHOSTRATIGRAPHY

Detailed stratigraphic and sedimentological studies in the central part of the basin by Murti, 1980 led to the division of the Chattisgarh Basin into a lower Chanderpur Group and an upper Raipur Group of the Chattisgarh Supergroup. Murti (1980) broadly adopted the stratigraphic nomenclature of Dutt (1964) but refined it further by introducing additional lithostratigraphic units following the norms of the code of Stratigraphic Nomenclature of India (1977). The detailed stratigraphic succession shown in the table.

A brief description of various litho units is given below :

2.0.3.1 Chandarpur Group

The Chandarpur Group is divided into Lohardih, Chaporadih and Kansa Pathar/ Kondkera Formations on the basis of lithologic characteristics. In the flat topped hills of Raitam- Aorai area of Raipur district, these units are well developed and the full sequence is revealed.

Lohardih Formation: The basement below the Lohardih, as noticed in a number of scarp sections in the area, is characterized by the development of paleosol. Broadly, the Lohardih can be differentiated into three lithounits viz. (1) basal conglomerate (2) arkosic/subarkosic sandstone and (3) lenses of conglomerate within the sandstone.

Basal Conglomerate: Overlying the granite basement is a thin horizon of poorly-bedded basal conglomerate which is generally ill-sorted and polymictic. Locally, it shows graded bedding and consists of angular to subangular clasts of vein quartz, microcline and granite derived from a granitic provenance. The clasts are usually

about 2-3 cm long but rarely reach upto 25 cm. The conglomerate is friable and poorly cemented, the matrix being very fine sand and light green clay. The grain size of the conglomerate decreases towards the top and grades into coarse-grained sandstone.

Sandstone: The sandstone is arkosic to subarkosic and consists of sub-rounded grains of quartz and slightly altered microcline. A few fragments of granites are occasionally seen. The sandstone shows sedimentary structures like cross-bedding, ripple marks, worm tracks etc.

Conglomerate Lenses in the Sandstone: The surface of the sandstone is at places studded with conglomeratic lenses, which measure 20-50 m. The conglomerate is oligomictic, unlike the basal conglomerate, and consists of angular-to sub-angular pebbles of vein quartz.

Chaporadih Formation: It is medium to very fine grained, thinly laminated sandstone with micaceous sheen and overlies the Lohardih conformably. It is reddish-brown in the western part, olive green in the eastern part and is characterized by authigenic glauconite. The Chaporadih has a thickness of about 15 m and forms a marker horizon in the

8

stratigraphy of the area. The sandstone is characterized by micro-cross-lamination. Other sedimentary structures include desiccation cracks, clay galls, flute-casts etc.

Kansa Pathar/ Kondkera Formation: These are time-equivalents and overlie the Chaporadih conformably.

Kansa Pathar Formation: It is represented by sandstone which is white, massive and coarse-to medium-grained. The conglomerate lenses, which are so frequent in the Lohardih, are absent here. It is ortoquartzite in composition with well rounded quartz grains. Detrital glauconite grains are observed occasionally. Various sedimentary structures like cross-bedding and ripple marks are noticed.

Kondkera Formation: The Kansa, Pathar shows gradational contact with the Kondkera and represents a prominent lateral facies change. This formation is represented by ferruginous sandstone, which is reddish brown, coarse-to medium-grained, massive and compact. Te individual grains in the sandstone are rounded to sub rounded. The sandstone essentially consists of quartz grains and is ortoquartzite or subarkosic. Microcline, slightly altered, is occasionally present. Quartz grains are iron-coated and the cementing material is siliceous. Sedimentary structures like cross bedding and ripple marks are noticed.

2.0.3.2 Raipur Group

The Raipur Group of sediments overlie the Chandarpur Group with errosional disconformity. The disconformable nature of the content is very clear between Birkoni and Tumgaon, where limestone has been deposited on the eroded surface of the sandstone. The Raipur Group comprises four Formations viz., Charmuria, Gunderdehi, Chandi and Tarenga.

Charmuria Formation: The Charmuria Formation is represented mainly by limestone with basal clay horizon (Sirput Member). The basal clay horizon is gritty and the color varies from dirty white to buff. The clays are interbedded with cherts which are white, crypto-crystalline and subvitreous. The Sirpur clays grade into the overlying limestone that is cherty in its basal part. The limestone is uniform in texture and lithology. It is micritic (calcilutite), well laminated, grey and pyritiferous. Sedimentary structures such as ripple marks are noticed occasionally. It corresponds to the Sarangarh limestone of Schnitzer (1969). Towards the top, the limestone grades into the pink shale of Gunderdehi Formation.

Gunderdehi Formation: Gunderdehi Formation in the area is represented by pink and grey shales, the latter occurring as a member in the middle of the sequence. The pink shale is medium to very fine grained, thinly-laminated and occasionally purple with mottled appearance. It is characterized by the presence of authigenic glauconite. Towards the top, excellent development of sedimentary structures like ripple marks, mud cracks and intra-formational shale-pebble conglomerate is noticed. This formation corresponds to Seorinarayan shale of Schnitzer (1969).

9

Dotopar Member: This is represented by the grey shale and occurs as a tongue within the shale showing gradational contact. The Dotopar is fine grained, thinly laminated, friable and calcareous. An intersecting feature of this member is the presence of authigenic barytes occurring as infillings in the septarian nodules which are noticed near Dotopar and Gabod. The barytes is intimately associated with chlorite. The nodules are dense, compact, oval-shaped, and range in diameter from 2 to 15cm. The long axes of the nodules lie parallel to the bedding. These nodules, with the network of the radiating cracks, look

2.0.3.3 Chandi Formation:

The Gunderdehi Formation is succeeded conformably by Chandi Formation (comprising three limestone Members) with a gradational contact. This Formation is characterized by prolific growth of stromatolites which occur as extensive reef complexes in the area. The Chandi Formation can be broadly divided into three Members viz., (1) Newari (2) Pendri and (3) Nipana, on the basis of lithological considerations. Dolomitization transgresses lithological boundaries. The Chandi formations constitutes a potential source of raw material for lime-based industries.

The Khairagarh sandstone of Dutt (1964) which precedes the Raipur shale-limestone in the southern part of Chattisgarh is not noticed in the area, where as sandstone is occasionally seen at the base of the Akaltara limestone sequence of Schnitzer (1969) in the area further northeast. Moreover, the Karuid I, and Karuid II and Akaltara- Lilagarh sequence constituting Cycle 2 and 3 overlying the Sarangarh-Seorinarayan cycle of Schnitzer (1969) are not present in the area.

2.0.3.4 Newari Member:

The pink, purple and medium-grained limestone representing the Newari Member conformably overlies the Gunderdehi Formation with a gradational contact. Near the contact with shale, the limestone is friable. Dolomitisation is noticed along the joints. Generally, the limestone does not show bedding particularly away from the contact of Gunderdehi Formation. Stromatolites, intraformational conglomerate and stylolites are the most common sedimentary structures in the limestone. Stromatolites are poorly-developed near the Gunderdehi contact but well developed away from it. Stromatolite columns are separated by calcareous mud and, on weathering, they stand out prominently. The Newari Member gradually grades into the Pendri Member towards west.

2.0.3.5 Pendri Member:

It consists of a fine-grained and grey limestone which is stomatolitic. A characteristicfeature of the Pendri Member is its invariable intercalation with grey shale and grey flaggy limestone. Clay pockets which are associated with shale intercalations in the limestone show the presence of illite and montmorillonite. There is preferential dolomitization in this algal limestone. The dolomite is coarse grained, porous, friable,

10

closely-jointed, and cream coloured. Dolomitisation is noticed along joints in limestone. Stromatolites tend to be stunted, show branching and are ill-preserved because of very fine lamination. Stylolites are commonly observed. The limestone grades into the overlying Nipania Member. The Pendri Member Corresponds to Bhatapara Limestone of Schnitzer (1969).

2.0.3.6 Nipania Member:

The Nipania Member consists of limestone which is coarse- to medium-grained, purple with mottled appearance. Sedimentary structures like stromatolites and stylolites are very common. Dessication cracks are noticed occasionally. The Nipania member gradually grades into the Tarenga Formation towards the top. It corresponds to Nandini limestone of Schnitzer (1969).

2.0.3.7 Tarenga Formation:

This Formation is represented by pink shale with inter-bedded chert. The shale shows pink and green colour banding and is glauconitic at places. Near Singarpur the cherts are inter-bedded with pure montmorillonite clays. The clay is olive-green, fine-graine, free from clastics and showing swelling of about 2-3 times. The clays are noticed upto a depth of 3m and analyse 9.48% K2O. The shale shows sedimentary structures like intraformational conglomerate. The cherts near Singarpur show casts of warm burrowings. The Tarenga Formation correspomnds to Patharia Umaraya series of Schnitzer (1969).

3.0 LOCAL GEOLOGY

Within the PL areas , grey to purple grey Chandi limestone underlain by purple Gunderdehi shale is found as established by the borehole studies. These rocks belong to the Raipur Group and are described under local geology.

Generally, grey limestone occurs on the top followed by purple-grey limestone, purple limestone and purple shaley limestone. The general strike is NE-SW with very low dip towards NW direction. The limestone shows excellent development of stromatolytes. Lack of clear and continuous bedding planes in the limestone indicate a period of continuous deposition under similar conditions without any parent break. Thickness of limestone broadly increases from SE towards NW.

The local lithological disposition is as under:

Laterictic Soil Dolomite Grey Limestone Greyish Purple/Purplish Grey Limestone Purple Limestone Purple Shaly Limestone

4.0 SCHEME OF INVESTIGATION

The scheme of investigation for proving cement grade limestone at C & E block in Sonadih was suitably framed by Lafarge involving topographical survey, geological mapping, diamond core drilling , logging & sampling, chemical analysis and preparation of prospecting report. The investigation was carried out over a total areaof 508.633 hectres divided into 5 no. of blocks. Core drilling was carried out on a grid interval of 150m x 150m, in the same line as it was done for proving Block-A, existing mining lease. A composite topographical map covering the total area with indivudual blocks demarcated on it was prepared by topographical survey in 1:5000 scale and 1 metre contour interval followed by geological mapping on the same scale. The entire area was prospected block-wise with 214 vertical boreholes covering 6920.6 metres of cumulative drilling to achieve the qualitative and quantitative assessment of the deposit. The various activities undertaken for prospecting are as under :

4.0.1 Topographical Survey

The entire area (508.633 hectare) was surveyed with the help of Total station taking reference coordinate N 3000, E 3000, RL 234.550 M from borehole 11/86 of Block A (existing mining lease). Surveying and plotting on the drawing were done for all

the ground features and structures falling within the survey limit. However, the area being more or less flat and devoid of any major structure, the survey work mainlyconsisted of drawing on perpendicular grid lines at 150 Mtr intervals at field in the same line as it was done for proving Block-A, existing mining lease. All the grid intersection points were established on the field by fixing pillars with their respective coordinates and their respective reduced levels . All the surface features were noted and contour map was prepared in 1:5000 scale.

13

4.0.2 Geological Mapping

Geological mapping of the entire area was carried out to produce a geological map on the same scale as that of the topographical map. During mapping 200 no. of samples from the surface outcrops were drawn from the entire area and analyzed. The geological map was prepared incorporating all major structural and lithological details present over the area along with dip, strike etc.

4.0.3 Diamond Core Drilling

Drilling was undertaken over all the PL blocks on prefixed grid interval of 150 Mtrwith the help of 13 diamond core drilling rigs. A total of 214 boreholes were drilled distributed over all the PL blocks covering 6920.60 Mtrs cumulative drilling. The borehole numbers, co-ordinates of the boreholes as well as the depth of each borehole were prefixed by Lafarge and are shown in the following table. It is worth mentioning here that out of 263 no. of scheduled boreholes spread over B,C,D,E & F blocks at 150 m interval, 214 boreholes were selected for drilling at the mineralized zones only to economize the cost of project as well as to cope up with the extremely squeezed time schedule for evaluation of cement grade limestone in the above PL blocks in Sonadih. However, areas falling beyond the selected borehole locations were delineated after establishing the formation boundary of different litho-units by geological mapping followed by few confirmatory boreholes.

4.0.4 Logging & Sampling

Core samples recovered from the boreholes were preserved systematically in wooden core boxes, and logged lithologically on the basis of visual inspection. The entire cores of a particular borehole were splitted longitudinally into two halves. One half was sampled and sent for complete analysis of major and minor constituents to laboratory of Lafarge at Sonadih & Arasmeta where as the other half of the cores and samples were kept at Sonadih for future reference in wooden core boxes with appropriate marking. Two meter

14

length of homogeneous core was considered for preparation of sample unless there was a change in lithological characteristics.

4.0.5 Computation of quality & reserve

After completion of all the above activities, compilation of data generated from field work and chemical analysis were done and geological sections were drawn for computation of quality of the deposit along with estimation of reserve.

5.0 QUALITY OF LIMESTONE

The primary objective of the investigation being qualitative and quantitative assessment of cement grade limestone along with its reserve within PL areas held by Sonadih Cement Plant, it has been accomplished following the technical specifications stipulated by Lafarge keeping the objective in view.

In this report, an estimate of cement grade limestone has been made satisfying the limiting value of 44.5 % CaO as an weighted average with acceptable MgO and SiO2. This limiting value is not for individual samples. Any CaO value which on being averaged in a specific thickness would result in the average quality of a band above 44.5 % CaO, has been considered for the purpose of this investigation as cement grade limestone. However, as quality deteriorates with depth as revealed by individual bore logs, and in view of the possibility of getting blended of lower grade material from lower benches with the higher grade stone available from the top benches, a cutoff values for CaO has been taken as 40% and for MgO 4.0%. Whereas limestone falling on the grade below 40% CaO and above 4% has been considered as mine rejects and has not been included in the reserve estimation.

5.0.1 Chemical Analysis

As per scope of work, all the individual samples prepared from the drill cores were analysed for their 8 radical constituents viz. CaO, MgO, SiO2, Al2O3, Fe2O3, Na2O, K2O and L.O.I in the laboratory of Arasmeta & Sonadih Cement Plant of Lafarge. The weighted average core quality for CaO and MgO of the cement grade limestone was calculated from the analythical results supplied by Lafarge by taking cut-off value of CaO more than 40% for each borehole separately.

5.0.2 Average Chemical Analysis

Major components along with minor ones viz. CaO, MgO, SiO2, Al2O3, Fe2O3, Na2O, K2O & LOI have been assessed for the entire deposit area since these components play the vital role in quality manufacturing of cement. The values of these weighted average of these components are given in separately.

15

5.0.3 Observations

The deposit is simple, without any geological, structural, topographical and chemical complexity. The overall Weighted Average core quality of the cement grade limestone for PL Area C & E Block is as under :

6.0 Reserve

considered to be the best suited for such type of deposit. The present geological report incorporates the complete data generated by drilling of 09 boreholes distributed in the parts of blocks, C & E along with analytical results of the core samples available from Lafarge. While limestone reserve has been estimated separately for each block, total limestone reserve in the entire area under investigation has been estimated by addition of reserves estimated in individual blocks. From each of these sections, the sectional areas of soil overburden, hard rock over burden and inter-burden (Dolometic limestone) and cement grade limestone were calculated separately for each of the block. Since estimation of reserve has been done by cross-sectional method with section lines drawn in East West direction, length of each section line has been generally considered from eastern to western boundaries of the individual PL blocks unless there exists any unworkable/restricted zone like pond, public road, canal etc. falling along the boundary lines or on the section lines. In such cases, length of section lines has been considered leaving the unworkable zone. Also, A block have not been considered while evaluating the total reserve under present scope of investigation. Moreover, stipulations laid down in Metalliferous Mines Regulation, 1961 were followed while doing this exercise.

6.0.1 Methodology used for Calculation

From each section, the sectional areas of soil overburden, hard rock over burden and inter-burden (Dolometic limestone) and cement grade limestone were calculated separately for each of the block. The sectional area of each of the rock type were multiplied by the lengths of influence of each section in order to arrive at their respective intersectional volumes. Since the boreholes have been drilled and geological sections are prepared at 150 m interval, each sectional area has been multiplied by 150 m , taking the aerial extent of influence as 75 m on either side viz. 75 m on the North and South, half way to the adjacent section lines to get the intersectional volume. The volume of cement grade limestone along each section line in each block was multiplied by its specific gravity (taken as 2.5) to achieve the geological reserve. For assigning the quality parameters, the weighted average of

16

individual bore falling on a particular section line has been determined. Afterwards, the weighted average of all the boreholes on a particular section line has been worked out. To work out the weighted average quality of the material of a particular section the weighted average quality of all the boreholes falling on the section line is multiplied by its total sectional quantity (Tones). Cumulative of weighted qualities and quantities of all the sections give the weighted average quality and reserve of the area. The detailed block-wise estimation of reserve are presented in the subsequent pages. However, 10 m reserve on either side of the road leading to Sonadih village and 50 m on either side of the canal has also been deleted from the gross reserve to determine net mineable reserve.

6.0.2 Net Geological Reserve

Considering 10% mining loss & 5% recovery loss, the net geological reserve may be

Block-C

a) Gross Geological reserve of Cement Grdae Limestone (Million MT)- 4.5

b) Less 15% towards cavities , calculation error etc- (in Million MT) 0.675

c) Reserve blocked due to canal , road etc.-(In Million MT)

Location of applied ML area

1.3Geology & Reserves:

Topography: The topography of the area is almost a flat having gentle slope toward

northern direction. The maximum contour level is 242 mRL and minimum is 236

mRL.

Drainage pattern: The Shivnath River flows from north to south and suddenly

takes turn near the northern boundary of the existing lease of the company which is

about 1.5 km from this lease area and flows towards ESE direction.

The River Shivnath and its tributaries viz Khorsi Nala and Jamuniya nala control

drainage of the area. Various streams originate from this and forms a network to

10

join this nala, which finally flows in SW-NE direction and meets the river Shivnath

exhibiting dendritic pattern in the most of the area. Beloda branch of the Mahanadi

canal enters the area from SSW part of the lease area and passes towards northern

part distributing water to the villages in its course. All the seasonal nalas flow into

the Shivnath River.

Vegetation: The common species in nearby villages are Babool, Neem, Pipal, Bargad,

Imli, Amla, Gulmohar, etc.

Climate: The area has sub-tropical climate with average annual rainfall ranging

from 80 to 90 cm. The rainy season starts from June to September with maximum

rain fall in the month of August. Sometimes intermittent showers accompanied by

storm are experienced in March and April before the on-set of monsoon. May is the

hottest part of the year with temperature going upto 470C while the usual

temperature ranges between 270C and 420C. January is the peak winter with

temperature varying between 280C and 130C.

The ground water level monitored around the applied area was found to be in the

range of 30 - 35 m, which corroborates from the finding of adjacent existing

operation. The limestone is hard, compact and massive in nature and devoid of any

secondary porosity like joint, fissures etc. to have potential ground water

occurrence. Adjacent mining operation has reached up to a depth of 32 m and

ground water has not yet encountered.

Regional geology:

The Regional Geology has been from the miscellaneous publication No. 30, PART

XXI, 2ND Revised addition, 2006 of Geological Survey of India, “Geology and Mineral

Resources of Chhattisgarh”.

The limestone and associated formation which is occurring near this village a part of

Chhattisgarh Synclinorium and belonging to Chandi Formation of the Raipur Group

of Chhattisgarh Supergroup. The limestone deposit is almost horizontally bedded

with local dip from 20 to 50 towards north. The general strike of the limestone bed is

east-west.

11

The interacratonic Chhattisgarh Basin is crescent shaped and covers about 33,000

sq km area in Raipur, Durg, Rajnandgaon, Bilaspur and Raigarh district of

Chhattisgarh and adjoining parts of Orissa. The basin has a maximum length of

about 300 km along ENE-WSW direction. The maximum thickness of sediments is

estimated to more than 2 km and is epicontinental or stable shelf type.

Local Geology (Lithology of the area):

Generally grey limestone are found on the northern part of the area followed by

purple grey limestone and purple shale successively towards south and similarly the

same sequence has been confirmed from borehole drilled during exploration. The

deposit is structurally undisturbed since basin deposition.

The local succession of the area is as under:

Soil (alluvial)

Dolomite

Grey Limestone Chandi Limestone formation

Purple - Grey Limestone

Purple Limestone

Purple Shale Gunderdehi Shale

Limestone is extremely fine grained, anhedral and occurs as massive, hard compact

body. Colour of limestone generally has a close relationship with quality. It is

observed that the grey limestone have higher CaO content and less MgO content

than the underlying purple limestone which has the intercalation of purple shale in

depth.

12

Technological Investigation (Exploration):

Details of technological investigation (pitting/trenching/drilling etc.):

A systematic geological investigation over the recommended ML area was

conducted by LIPL. The geological investigations include topographic survey,

geological mapping, and diamond core drilling and surface sample analysis.

Subsequent to the grant of the PL, LIPL formulated an exploration program for the

PL area. The execution of the exploration campaign was carried out under

supervision of LIPL. The exploration activities were carried out in two different

phases in the years 2002-2003 and 2006, respectively.

Initially, a thorough reconnaissance of the PL area was carried out, in order to

assess the potential area to start with the prospecting operations and exploration

restricted within recommended ML potential limestone bearing area with no mining

constraints. As stated earlier, the entire area is concealed beneath soil cover, hence

the lithologies exposed in dug wells/ dug pits formed the basis for borehole

planning and subsequent exploration activities.

Altogether a total of 9 vertical boreholes were drilled with a total meterage of 940 m

in granted total PL area. The summary of exploration activities carried out by LIPL

during geological exploration campaign is given in the table below:

Al2O3, Fe2O3, Na2O, K2O and LOI) 142 nos.

Data spacing for reporting of Exploration Results:

The scheme of investigation for proving existence of cement grade limestone at

granted PL blocks was suitably framed by Lafarge involving topographical survey,

13

geological mapping, diamond core drilling, logging & sampling, chemical analysis

and preparation of prospecting report.

Topographical survey of entire area was done with the help of total station.

Surveying and plotting on the drawing were done for all the ground features and

structures falling within the survey limit. However the area being contiguous to

existing operating mine and more or less flat and devoid of any major structures, the

survey work mainly consisted of drawing of grid lines at 150 meter intervals at field

in the same line as it was done for proving existing mining area. All the surface

features were noted and contour map was prepared in 1:1000 scale with 1 m

contour interval.

Since the area is adjacent to existing mine working, therefore pitting and trenching

was not done. During the course of detailed exploration, total 9 boreholes were

drilled in the area on a grid pattern of 150 m X 150 m.

The grid pattern for regular deposits like limestone should be less than 200 m X 200

m for considering the reserve under G-1 category, thus the exploration work carried

out by LIPL at the area held under prospecting license and established reserve can

be considered under the G-1 category.

Location of Data Points:

The recommended ML area of 19.219 Ha has been covered under topographical survey.

The topographic map was prepared on a scale of 1:1000 with a contour interval of 1.0 m.

Considering this, locations of the total 9 nos. of bore holes were placed and collar were

identified during the exploration campaign.

The topographic plan has formed the base for the geological plan. The entire geological

setup of the recommended ML area comprising of the existing lithological sequence and

their structure is superimposed on the topographic plan to generate the geological plan.

- Quality and adequacy of topographic control.

Survey was carried out with the help of Total Station with reference to the coordinate N

– 3000, E – 3000, RL – 234.550 M from borehole 11/86 of Block – A (existing mining

lease).

14

Surveying and plotting on the drawing were done for all the ground features and

structures falling within the survey limit. However, the area being more or less flat and

devoid of any major structure, the survey work mainly consisted of drawing on

perpendicular grid lines at 150 m intervals at field in the same line as it was done for

Block-A, the existing mining lease. All the grid intersection points were established on

the field by fixing pillars with their respective co-ordinates and their respective reduced

levels. All the surface features were noted and contour map was prepared in 1:1000

scale.

Sampling Technique:

Core samples recovered from the boreholes were preserved systematically in

wooden core boxes. The entire cores of a particular borehole were splitted

longitudinally into two halves. One half was sampled and sent for chemical analysis

and the other half of the cores were kept for future reference in wooden core boxes

with appropriate marking. Two meter length of homogeneous core was considered

for preparation of sample unless there was a change in lithological characteristics.

Proper sampling equipment (PW 4400 AXIOF- XRF) was used to ascertain iron-free

milling and pulverization subsequent to chipping by jaw crusher. Two sets of

powdered samples were prepared from the split –half core by standard method of

coning and quartering and sieving to 100 mesh powders. The standard practice of

levelling envelopes was followed. One set of sample was utilized for conducting

chemical analysis and the other set was preserved for future reference. The

sampling was done by LIPL’s expert.

Drilling Technique & Drill Sampling Employed:

Diamond core drilling was undertaken in vertical boreholes in NX size by double

tube core barrel arrangement. Drill rigs of Voltas and L & T make (Model- Joy 12 B,

LT 175) having a capacity of 100 – 300 m along with all relevant accessories and

well-trained drill crew were employed during the exploration campaign.

15

The minimum and maximum run wise core recovery achieved in the bore holes

drilled is 0% (in overburden soil region, where sludge samples were collected) and

100% respectively.

Drilling was undertaken over entire area on prefixed grid interval of 150 m with the

help of 13 diamond core drilling rigs.

-Whether core and chip sample recoveries have been properly recorded and

results assessed.

The run wise recovery from each of the boreholes was properly recorded and

analyzed for their LOI, SiO2, Al2O3, Fe2O3, CaO, MgO, Na2O and K2O contents. The

individual lithounits along with the contacts as established from the core was noted

and sample intervals marked.

-Measures taken to maximise sample recovery and ensure representative

nature of the samples.

Diamond core drilling machine of reputed make Voltas and L & T make (Model- Joy

12 B, LT 175) having a capacity of 100 – 300 m with double tube core barrel,

connected to a consumable core drilling bit, typically made with synthetic diamonds,

which is the core cutting tool were used for drilling to maximise sample recovery

and ensure representative nature of the samples.

- Whether a relationship exists between sample recovery and grade and

whether sample bias may have occurred due to preferential loss/gain of

fine/coarse material.

Core recovery in the overburden soil region, where sludge samples were collected

are very less, whereas core recovery over massive limestone is up to 100%. In case

of Dolomite and Dolomitic limestone also the core recovery is high. Limestone in

contact with the soil, clay, clay pockets and shaley limestone are encountered less

recovery with inferior grade.

-Logging: -Whether core and chip samples have been logged to a level of detail

to support appropriate Mineral Resource estimation, mining studies and

metallurgical studies.

16

Core samples recovered run wise from the boreholes were logged throughout the

length of the borehole lithologically on the basis of visual inspection. The individual

lithounits along with the contacts as established from the core was noted and

sample intervals marked.

Sub-Sampling Technique and Sample Preparation:

-If core, whether cut or sawn and whether quarter, half or all core taken.

Individual core samples representing thickness of lithological units of interest or

part thereof were drawn by splitting the core in two equal parts.

-If non-core, whether riffled, tube sampled, rotary split etc. and whether

sampled wet or dry.

Not Applicable

-For all sample types, the nature, quality and appropriateness of the sample

preparation technique.

One half of the core was retained in the core box and other was crushed and two

sets of powdered samples were prepared from the split – half core by standard

method of coning and quartering and sieving to 100 mesh powders. The standard

practice of levelling envelopes was followed. One set of sample was utilized for

conducting chemical analysis and the other set was preserved for future reference.

-Quality control procedures adopted for all sub-sampling stages to maximize

representivity of samples.

Half split core samples were systematically crushed, coned quartered by applying

grain size/quantity principles for forming representative powder sample. PW 4400

AXIOF- XRF sampling equipment was used to ascertain iron-free milling and

pulverization subsequent to chipping by jaw crusher.

-Measures taken to ensure that the sampling is representative of the in situ

material collected.

Diamond core drilling was conducted and all the samples were collected from the

drilled bore holes to ensure the sampling is representative of the in situ.

17

-Whether sample sizes are appropriate to the grain size of the material being

sampled.

Since limestone grain size is medium to fine, all the samples were sieved to 100

mesh powders for chemical analysis purpose.

Quality of Assay Data and Laboratory Tests:

All the individual samples prepared from the drill cores were analysed for their 8

radical constituents viz CaO, MgO, SiO2, Al2O3, Fe2O3, Na2O, K2O and LOI in the

laboratory of Sonadih Cement Plant of Lafarge by using most advanced sampling

technique of XRF analysis using PW 4400 AXIOF instrument.

The weighted average core quality for the CaO & MgO of the cement grade limestone

was calculated from the analysis results.

Limestone CaO (%) SiO2 (%)

Grey Limestone 42.00-48.00 08.00 – 11.50

Moisture: The tonnages are estimated with the natural moisture content.

Bulk Density:

The Specific Gravity (SG) of limestone has been assumed as 2.5 which is the standard

value for limestone. In general Specific Gravity of limestone varies from 2.3-2.7. One

cubic meter of in-situ limestone by volume has been considered to be equivalent of

2.5 tonnes by weight. OB soil bears a SG of 1.8, the interstitial clay bears the SG of

1.2, Shale bears a SG of 2.2, whereas all other lithounits bears the SG of 2.5 (same as

limestone).

Resources Techniques:

The methodology adopted for estimation of resources is as follows:

Geological Cross Sectional Method

In consideration of the intensity of exploration carried out, the geological/

structural setup of the deposit and configuration of concession area clubbed with a

number of constraints, estimation of limestone resources on the basis of geological

cross sectional method has been adopted for limestone resource estimation. The

18

cross sectional area was multiplied by 150 m, considering 75 m aerial extent on

either side of the section line on north south. The quantity of overburden and rejects

to be mined along with limestone has also been calculated by cross sectional

method.

The cross sections have been drawn along the section lines trending East-West on

drilling grid and attitude of beds. In order to know the lateral and depth wise extent

of mineralization, the lateral limits of mineralization on the cross sections have been

marked on the basis of correlation with subsurface geology based on structural

disposition and chemical analysis of core samples generated during drilling.

Surface Area

The explored area falls under different

categories were drawn in plan on the

basis of their limits on cross sections and

lateral limits extended. In addition to this,

polygons for different constraints were

also drawn and superposed over the

exploration category polygons in order to calculate the area blocked under different

category. All the polygons so made were assigned separate identity.

Specific Gravity (SG)

The Specific Gravity (SG) of limestone has been assumed as 2.5. One cubic meter of

in-situ limestone by volume has been considered to be equivalent of 2.5 tonnes by

weight. OB soil bears a SG of 1.8, the interstitial clay bears the SG of 1.2, Shale bears a

SG of 2.2, whereas all other lithounits bears the SG of 2.5 (same as limestone).

The SG values, for tonnage calculation, were applied to the litho units which were

estimated.

Tonnage Calculation

The formula used for resource estimation is given below:

Tonnage = CA x AE x Sp. Gr.

19

Where, CA = Cross sectional Area of limestone/ other litho unit (m2)

AE = 150 m Aerial Extent of section line of limestone/ other litho unit (m)

Sp. Gr.= Specific Gravity

Further work:

The exploration work carried out at recommended mining lease, already covered

lateral extension and depth of the area as per UNFC classification under G1 Category,

hence no further exploration has been proposed in applied ML area.

Any Other Information:

LIPL has invested an amount of Rs. 1.04 Crores for systematic and scientific

exploration of the all sanctioned PL areas.

Mineral Resource Estimation For Conversion To Mineral Reserve

Categorization Of Resources:

The reserves and resources of limestone has been estimated as per the UNFC

guidelines by cross-sectional method. In consideration of the intensity of exploration

carried out, the geological/ structural setup of the deposit and configuration of

concession area clubbed with a number of constraints, estimation of limestone

resources on the basis of geological cross sectional method has been adopted for

limestone resource estimation. The cross sectional area was multiplied by 150 m,

considering 75 m aerial extent on either side of the section line on north south. The

quantity of overburden and rejects to be mined along with limestone has also been

calculated by cross sectional method.

The cross sections have been drawn along the section lines trending East-West on

drilling grid and attitude of beds. In order to know the lateral and depth wise extent

of mineralization, the lateral limits of mineralization on the cross sections have been

marked on the basis of correlation with subsurface geology based on structural

disposition and chemical analysis of core samples generated during drilling.

The parameters considered for reserve estimation are as under:

i) The total applied lease area is 19.219 Ha.

20

ii) Mapping: The lease area has been surveyed by Total Station and preparing

detailed topographical-cum-geological map including all surface geological features,

extent of deposit, structural features, location of bore-holes and the assay-plan has

been prepared on 1 : 1,000 scale with contour interval of 1 m, accordingly the

Surface Plan has been prepared.

iii) The grid along with temporary survey station points have been marked on the

maps.

iv) The general surface level of the area is 239 mRL, maximum surface level of the

area is 242 mRL and minimum is 236 mRL.

v) A total 9 vertical core bore-holes were drilled in the area, at 150 x 150 m grid

interval.

vi) The reserve has been estimated by cross-sectional method. The limestone

bearing areas have been estimated by cross-sectional method and its influence area.

vii)The depth continuity of mineralization has been considered limited to the depth

upto wich direct evidence on mineralization is established through the boreholes.

viii) The quality requirement of limestone for Cement Plan is under:

CaO% 42 ± 2

MgO% 3± 1

SiO2% 10± 2

ix) Limestone occurring in this area has been divided into three different categories

so that required feed to the cement plant is achieved by proper blending, so that the

required quality is obtained on day to day basis.


Cement grade limestone (CGL) + 42 Max 4



21

x) The bulk density of limestone has been considered as 2.5.

xi) In the major part of the area, the top surface level varies from 242 - 236m.

Therefore, from mining point of view, a level of 239 m has been taken for making

the lower benches of 8 m each and, the accordingly the bench-wise reserve has been

estimated.

xii)The reserve has been estimation block-wise and bench-wise separately.

The limestone of the area is stratiform, stratabound, tabular of regular habit and as

the detailed exploration by drilling boreholes on 150 x 150 m spacing on grid

pattern has been carried out over the entire lease area covering all the eight blocks,

the resources estimated has been categorized under Measured Mineral Resources,

Code (331).

But, some portion of the applied lease area is devoid of boreholes or very far away

from the borehole drilled, thus these areas has been considered under Inferred

Mineral Resources, code (333).

The total reserves and resources are as under:

3. Mining Method:

3.1Mining:

The company is having cement plant of 3.5 MTPA clinker capacity in village Sonadih,

for this 5.5 million tonnes of limestone will be required.

The production rate of limestone will be depends upon production of limestone

from all the mines of the company.

The mine will be designed and the deposit will be exploited with minimum damage

to environment and optimum utilization of limestone for captive use in the Cement

Plant.

The salient features of mine design will be as under:

(i) The overburden is in the form of top soil cover, murrum, yellow soil and clayey

material of variable thickness. The overburden will be removed by dozer, and

23

loaded by excavator into dumpers and transported to the temporary stock yard and

will be utilized for plantation.

(ii)The surface level varies from 242 – 236 m. Therefore, from mining point of view,

a level of 239 m has been taken for making the lower benches of 5 m each and, the

accordingly the bench-wise production will be taken up.

(iii) The working will be carried out in 2 shifts with staggered roaster manpower

deployment in 350 days in a year.

(iv) Limestone is bedded deposit, massive & compact in nature, hence, the ultimate

pit slope of 500 will be quite stable. For a bench of 5 m height, floor width of 3.5 m

will be maintained. Presently, the working width will be maintained at about 20 m.

(v)The rain-water and seepage water collected in the pit will be stored in the lower

benches and will be used for spraying on the haul-roads and for plantation.

(vi) The floor of the working faces will be kept slightly sloping to facilitate flow of

water towards the sump during the rainy season to keep the working faces dry.

(vii) For blasting, 104 mm dia and 8 m (+0.5 m perihole) will be drilled with

compressed-air-operated wagon drills. The blasting will be done by

ANFO/SME/Slurry as column charge and slurry /cast booster explosive as booster

charge. Controlled blasting will be practiced by using Nonel detonators.

(viii) Hydraulic rock breaker will be used for breaking oversized boulders in place of

secondary blasting.

(ix) Hydraulic excavator of 3.5 cum capacity will be used in combination with 35

tonner dumpers for loading and transportation of limestone.

(x)The limestone ROM will be directly transported to the cement plant after

crushing and screening (if required).

(xi) The haul distance from mine site to crusher is about 3 to 5 km.

(xii) For the purpose of grade control, samples will be drawn from each blast/blast

holes and will be analysed for its grade.

(xiii) The requirement for making clinker, the average chemical composition of

limestone should be maintained is as under:

24

CaO% 42 ± 2

MgO% 3± 1

SiO2% 10± 2

(xiv) The limestone occurring in this area has been divided into four different

categories so that the required feed to the cement plant is achieved by proper

blending at the crushing plant, so that the graded quality is achieved on day to day

basis.


Cement grade limestone (CGL) +42 Max 4



(xv) The sub-grade of limestone produced from the mine will be separately stacked

and processed by suitably blending as per requirement. The blending ratio will vary

according to parameters of raw mix from time to time.

(xvi) The Staker – Reclaimer and Raw-Mills operations will be governed by

Production and Quality Control department of the Cement Plant, which will also co-

ordinate with Mine Management to dispatch particular quality of crushed limestone

as may be required, so that the Raw-Mix design suits the required parameters i.e.

LSF, SM and AM, etc.

(xvii) All efforts will be made considering eco-friendly mining in the area. For this,

dense plantation will be done all around the lease area in the non-mining zone to

improve aesthetic beauty and for development of green belt.

(xviii) The mining loss during the mining of limestone is expected as about 10% of

the total ROM due to intercalations, fractures, clay pockets, voids, cavities, etc.

Out of this, 5% will be considered as waste/intercalations and kept separately and

remaining 5% will be due to voids and cavities. This will be temporary stocked

within the lease area and utilized for road maintenance from time to time.

Required power for the cement plant as well as mines is obtained from Central

Power Distribution Corporation Limited.

Labour Supply & Skill: Adequate skilled labour is available in the region.

35

7.0 Other Modifying Factors:

At present no national parks, historical monuments exist in the proximity of

proposed mining lease area and no tribal issues are foreseen. The applied ML area of

19.219 Ha. comprises of mostly private land owned by local villagers and some

government land. No mining activities will be carried out before grant of Mining

Lease and before land acquisition.

LIPL will implement the statutory and legal obligations and special conditions

imposed, if any, by the following statutory agencies:

a) During grant and execution of lease deed by Directorate of Mines and Geology,

Govt. of Chhattisgarh

b) Directives issued by Indian Bureau of Mines

c) Directives issued by Directorate General of Mines Safety

d) Conditions imposed by Ministry of Environment and Forests

e) State or Central Pollution Control Board

f) Any other statutory organization describing the nature of conditions and

compliance position thereof.

The mine will be working systematically and scientifically since decades in profit

and it has never faced any major problem which might have affected the mining

project and put it at any kind of risk. Therefore, looking for the past history for the

mining project for such a longer period no assessment of risk at the moment or in

near future is considered necessary.

Statutory Provisions Relating to-

Labour: All applicable Labour Laws are inforced and will be implemented. The

labourers will be getting all benefit as per Provisions of Mines Rule 1956, ID Act

1980, Contract Labour (Reg & Abolition ) Act, Bonus Act, Maternity Benefit Act,

Payment of Wage Act, Minimum Wage Act, persons (labourers) will be employed

strictly as per the provisions of the prevailing Labour Laws and Rules there under.

36

Land: Almost the lease area belongs to Private land and some part is belongs to

Govt. land. The compensation and other statutory formalities will be complied as

per norm of the State Govt.

Mining: Mining will be done strictly as per the approved Mining Plan/ Scheme of

Mining as applicable and the provisions of all Acts, Rules and regulations made there

under and the same practice will be followed.

Taxation: Taxes and cess as applicable will be paid as per the laws

Environmental Management

LIPL’s commitment with special emphasis on the protection of environment is given

below:

Air Quality

Wet drilling to suppress the dust emission from the drill machines at its source by

inbuilt water injection system

Fixed continuous water spraying system on the haul road from working pit to the

crushing plant

Automised water spray system at Limestone hoppers

Regular water sprinkling on blasted heaps and haul roads with water tankers.

Use of sharp drill bits for drilling holes and arrangements for bit regrinding.

Charging the holes by using optimum charge and using time delay detonator.

Avoiding blasting during high windy periods, night times and temperature inversion

periods.

Regular grading of haul roads and service roads to clear accumulation of loose

material.

Excavation operations are suspended during periods of very strong winds.

Avoiding over filling of dumpers and consequent spillage on the roads

The vehicles and machinery are kept in well-maintained condition so that emissions

are minimized.

37

Afforestation for control of dust. To arrest the amount of airborne dust, extensive

plantation will be carried out within the mines and outside the mining lease.

Plantation of wide leaf trees, creepers, tall grass along approach roads, and on safety

barrier zones will help suppress dust.

Road berms and dumps will be turfed and planted.

Operator cabins in all items of major HEMM equipment will be enclosed, to

minimize dust exposure of the operators.

Noise Levels

The following noise abatement measurements will be adopted:

Proper and regular maintenance of vehicles, machinery and other equipment.

Carrying out blasting only during day time and not on cloudy days

Limiting time exposure of workers to excessive noise.

The noise generated by the machinery to be reduced by proper lubrication of the

machinery and equipment.

The workers employed will be provided with protection equipment, earmuffs and

ear-plugs, as a protection from the high noise level generated at the plant site

wherever required.

Noise levels are also controlled by using optimum explosive charge, proper delay

detonators and proper stemming to prevent blow out of holes.

Proper and timely maintenance of mining machinery

Speed of trucks entering or leaving the mine will be limited to moderate speed of 25

kmph to prevent undue noise from empty trucks

Water Pollution Control Measures

Mining activities may cause adverse impacts due to mine drainage, siltation due to

storm water and contaminated water from workshops and domestic sewage water.

In order to mitigate the likely impacts the following management has been

proposed.

38

Storm Water Management

Apart from construction of the bund, a garland drain will be provided outside the

bund to stop water from entering into the mine. A check dam is proposed at the end

of the drain for trapping the silt. The water overflow from the check dam will drain

to Shivnath river through the existing seasonal nalla.

A garland drain surrounding the temporary dump area with sedimentation pits will

be provided. The silt free water will be discharged to the natural drainage pattern.

Waste Water Management

Open cast mining of the limestone will not generate any waste water. As there is no

mineral processing, no waste water will be generated. However, small quantities of

domestic waste water will be released from the mines site.

At the workshop area, an oil separation tank will be used to segregate oil & grease

from the outlet water of service ramp. Only clean water will be let out after

skimming the oil and grease. This treated water will be used for plantation purpose.

Proposed Afforestation

Extensive plantation will be carried out at the following locations:

7.5m wide greenbelt all along the mine lease area.

Each side of the proposed haul road and road leading to crusher

Occupational Health and Safety

LIPL has established its own well equipped occupational health center at the site. All

the employees in the mine undergo periodical medical examination.

LIPL has also attained the Occupational Health & Safety assessment system 18001

certification. All the mining operations are and will continue to be carried out

strictly in accordance with the Mines Act, Rules & regulations. These practices will

continue at the new mines also.

39

8.0 Classification:

The subject area is fall under “Stratiform, Stratabound and Tabular Deposit of

Regular Habit” as per UNFC classification and suitable for working with opencast

method of mining. Preliminary mine design / conceptual plan may be prepared after

obtaining all necessary approvals from statutory authorities for working of mine.

Since, LIPL is operating existing mine adjoin to recommended ML area and has

obtained all necessary permits it is expected that permits for recommended ML area

will be obtained within a reasonable time frame after grant of Mining Lease.

Considering the above study Reserve at recommended ML area can be classified

under 121 and 122 category of UNFC.

After the pre-feasibility study and economic axis study the limestone has been

categorized as per the norm of UNFC is as under:

The mineable reserves of limestone is 31,99,536 tonnes (say 3.199 million tonnes)

and proposed maximum production rate is about 1.5 lakh tonnes per annum.

6. Conclusion:

a. The deposit has been explored in a square grid of 150 m and reserve has been

established under proven category.

40

b. The mine will be captive mine and catering to the need of limestone to plant for

manufacturing cement in a constant basis since inception. For raising the limestone

from captive quarry in a systematic manner an approved mining plan, subsequently

review through schemes has been in place.

c. The reserve established is meeting the threshold of manufacturing the cement as

prescribed under NCCBM Norms.

d. On the basis of the detailed exploration (G-1) done over the entire lease area,

Mining Plan has been prepared, having enough experience specific and end use

grade of reserves and specific knowledge of forest/non-forest and other land use

data, the economic viability of the mining project has been proved beyond doubt

and thus the mineable part of the mineral resources which fall under the Ultimate

Pit Limit (UPL) and is above the threshold value and above as bifurcated correspond

to the Economic Axis (E-1) and the remaining resources as bifurcated above falling

outside UPL that is falling within the statutory barrier correspond to the Economic

Axis (E-2).

e. This project required investment of about ` 8.14 crore and the NPV will be about

` 499781443/-, IRR about 96% and payback period will be about 2 years per the

Pre-Feasibility Study done, cost of limestone production will be ` 250/- which is

comparable being incurred by existing cement plants in the region which are

operating probability in the region. The operating the mining lease is economical

viable.

f. Thus, considering the entire above points as per the Guideline issued by Govt. of

India, Ministry of Mines, Indian Bureau of Mines, the Feasibility Axis is comes

considered as E-1.
