2.4 GEOLOGY

2.4.1 Regional Geology

The region of the subject area belonging to Peninsular Gneiss of Archean group. The

Peninsular Gnessic Complex comprising migmatite gneiss, grey granodiroite, porphyritic

granite and intruded by dolerite and aplite veins. The Peninsular Gneissic complex

comprises of gneiss-migmatite-granite suite of rocks. They are highly variable in

mineralogical composition appearance structure and relative ages. The individual

members have not been distinguished in a major part of the area. However, granite and




migmatite gneiss occupy a large part of the area while bands of relatively younger coarse

– grained gneissic granite occur in the north eastern part.

The Anantapuram belt located along the Peninsular Gneissic Complex comprises a

complex assemblage of gneissic variants and granitic rocks which occupy almost the

entire lease area the Peninsular Gneissic Complex in the area is representing mostly by

Biotite bornblende gneiss granite and migmatite in north eastern part of the lease area and

made up of rocks of high grade metamorphism, migmatisation and intense deformation.

These granites, which are often porphyritic, are intrusive into the gneissic terrain and

contain alkali feldspar space. The later in parts the colour to the gneissic terrain and

contain alkali feldspar space. The later in parts the colour to the granite which ranges

from light to deep pink because of the massive nature of these intrusive they area

amenable for producing large size blocks, due to the wide spaced joint pattern imparted

to them. The granite deposits are mostly confined to the belt between Gudipala and

Anantapuramu.

2.5 GEOLOGICAL RESERVES

The recovery factor is considered as 96% with 4% interstitial voids and fractures. There

will not be any mining losses excepting handling loss which will be again recovered

during further loading

Total Mineral reserves:

The reserves are estimated basing field traverses and the litho log of the well inventory in

the adjacent agricultural fields and cross sections drawn on the ore body. The area of the

influence and the cross sections were taken at 46 m on an average i.e, 42 m on either side

of the cross section. The occurrence of the Granitoid gneiss is more than 55.0 m BGL.

Based on the field traverse and correlated data from the boreholes in the adjacent

agricultural lands to a depth of 70.0 m, the estimated reserves are considered as Proved

reserves. The cross sections A-A’, B-B’& C-C’ are considered for computation of

reserves. The present area which is explored is considered for computation of reserves

under G-1 category.

Quarry s Manager, skilled & unskilled labour about 30 persons.




3. EVALUATION OF IMPACTS

3.1 INTRODUCTION

Opencast mining activity causes some adverse impacts on the surround environment

unless proper environmental management plan is adopted. Selecting suitable sites for

mining and adopting the guidelines prescribed by the Ministry of Environment & Forests

(MoEF) and Indian Bureau of Quarry (IBM), one can minimize the major possible

impacts.

In this chapter, an attempt has been made to quantify the possible environmental impacts

on various features such as air, water, noise, land, ecology and socio-economies. The

following aspects have been studied to identify the possible impacts while achieving the

total production of 39917 cum/year of Road Metal & Building Stone.

The magnitude and significance of the environmental pollution caused by mining

depends on method of mining, scale and concentration of mining activity.

3.2 AIR ENVIRONMENT

The impacts on air environment from a mining activity depend on various factors like

production capacity, machinery involved, operations and maintenance of various

equipments and vehicle. Apart from these, there will be other activities associated viz

transportation of mineral and waste, stocking facilities and dump management within the

Quarry lease area that may contribute to pollution.

3.2.1 SOURCES OF DUST EMISSION

The proposed mining will be carried out by opencast other than fully mechanized mining

method with drilling and blasting. Based on the various operations involved in the

production of Mineral, the various emission sources has been identified as given below.

a. Point soruces

b. Area sources.

c. Line sources.




Drilling operations in the Quarry are considered as point sources. Extraction of Mineral

from Quarry are considered as area sources. Transportation of material from mining

benches to various end points are considered as line sources. The impact of above sources

on air environment is discussed below:

a) Drilling & Blasting

Drilling and blasting plays an important role extraction Rom of Road metal and building

stone. The primary drilling is done with Crawler drills of 4.5” diameter and secondary

drilling is done with jackhammers and compressor. The compressor attached to the

wagon drill has 450 CFM capacity and compressor attached to jack can cater needs of 2

jackhammers. Generally Once the boulder is freed by removing the soil and waste rock

surrounding it, a series of holes are drilled by compressed air using Jack Hammer at a

regular interval of 15-30 cms depending on the size of the boulder, the depth of the hole

depends on the height of the boulder and the holes are drilled up to the bottom leaving

about a foot at the base. The holes have to be perfectly straight and vertical so that the

vertical split is obtained. Line drilling machine can be used to drill straight holes. Feather

and wedges are inserted into the holes and hammered continuously applying uniform

pressure and the boulder splits vertically. Similarly dressing is done and the boulder is

given a rectangular shape. All the defects are avoided during the dressing stage. Diamond

wire saw may also be employed to dislodge the block from the parent rock.

Drill hole pattern will be uniform single lined pattern, equidistances holes from 0.33 m to

0.75 m , 4.5 m in depth. Spacing depends upon the size of the boulder, in general it 15

cms from hole to hole for better splitting.

The concentrations due to low explosives blasting will be confined to a maximum

distance of 10 m from the area of blasting. These concentrations will not be emitted

continuously. However presence of personnel near the blasting site during blasting will

be totally avoided. So, the impact of blasting on the air environment will be minimal.




b) Extraction & Loading

Extraction & Loading will be done by excavator and loader and these activities of Quarry

operation is contributing to the area source emission and the extent of influence of this

operation is about 100 m2.

c) Haulage &Transportation

In the operating Quarry, Tippers of 20 T capacity will be utilized for transportation from

the leased area to crusher. The other source of air pollution is due to the dust generated

during the movement of tippers on the haul road.

The above sources, which include drilling, low explosives blasting, excavation, haulage

for transport of blocks will contribute to dust pollution in the air.

3.2.2 ANTICIPATED IMPACTS

The impacts envisaged due to mining activity are evaluated based on various factors. The

emission inventory of the pollutants is as follows, the main air pollutant would be dust or

particulate matter generated by handling and transportation of Road metal & Building

Stone. But the impact of mining operations on air quality is minimum as mining involved

method by using jackhammer drilling & low explosive blasting and as the production

quantity is very less i.e. 133.05 Cum/Day only.

3.2.2.1 Dust Generation and Control

The air pollutant would be dust or particulate matter generated by handling and

transportation of Road Metal & Building Stone. The existing ambient air quality at quarry

lease area is within the limits prescribed by A.P.P.C.B. The envisaged production of

Mineral is only 133.05 Cum/Day. The dust generated due to mining operations will be

controlled by water sprinkling through water tankers.

3.3 NOISE ENVIRONMENT

Noise will be produced at the Quarry is due to operations of machinery, drilling, blasting,

and movement of vehicles. The noise generated by the mining activity is dissipated

within a small zone around the Quarry. The present noise levels at quarry lease area are




within the limits prescribed by A.P.P.C.B. There is no major impact of the mining

activity on the vicinity however; pronounced effect of above noise levels will 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 located far from the Quarry site.

3.4 WATER ENVIRONMENT

The Mining activity will be carried out on mound slope will not have any effect on the

ground water and the static water table in this area is below 50-60 m.

3.4.1 Impact on Surface Water

There are no major streams and rivers, which can get effected by the mining. Hence,

there will be no effect on the surface water.

During the present plan period quarrying will go to depth of 10 meters from the present

level of mining. During the monsoon period, the rainwater, if gets stagnated, will be

drained out. The benches will made with an inward slope to facilitate run off more faster

on to the Quarry floor. Small bunds, garlands and silting tanks also will be constructed to

minimize inflow muddy water which carries fine material.

3.4.2 Impact on Ground Water

Mining activity will be above the BWL (50-60 m). Hence, there will be no effect on the

Ground water levels.

3.4.3 Impact on Water Quality

Water quality in the buffer zone have indicted that the ground water is free from heavy

metal concentration and this mining activity will not interference on the water quality.

3.4.4 Water Consumption & Wastewater Generation

The water requirement for this proposed mining activity will be 5.5 KLD. Breakup

details are:




Sl. No: Purpose Quantity (KLD)

1 Dust suppression purpose 3.5

2 Domestic purpose 1.0

3 Greenbelt purpose 1.0

Total 5.5

There is no generation & discharge of wastewater from this Quarry.

3.5 LAND ENVIRONMENT

Various components of land environment have been identified for study of impact of the

Quarry operations. Details of the same are given below:

3.5.1 Solid Waste Generation

There is no mineral reject or sub-grade mineral in this quarry. However, about 6%

interstitial voids and intercalated waste is anticipated which is computed separately. This

will be utilized for the formation of internal roads and balance utilized to form a barrier

all along the 7.5m buffer zone of the QL applied area to a height of 6.0 m.

About 1633 m3/Year of waste will be generated from this Quarry. The western side of the

area is selected for dump yard for next five years and the waste will be stocked over an

extent of 750 m2 as enmarked in plate No.5.Lay out of Mine Working, pits, road, etc.

During this period, it is proposed to exploit to the tune of 199585m3 to an average depth

of 12m over the lease area from RL of 103 to 115 as shown on plate 5.

There is no problem in the quality of Road Metal & Boulder stone which confirms to the

specifications Aggregates.

The applicant proposes to carry out mining by opencast other than fully mechanized

method with drilling and blasting. The mineral will be sized and sorted in crusher for

desired size separation. Trucks/tippers will be deployed for transportation.




3.5.2 Impact on Land use

The Quarry is located in an area of 4.960 Ha. No forestland is involved.

After the operations cease, the Quarry spoiled area will be back field. It may not be

possible to complete regain the original topography of the area. During quarrying

whatever solid waste is generated shall be dumped at dumping site in inside the Q.L.

area. The mining lease area is not a part of any type of forest. Entire Quarry lease area is

govt. land hence all the impact on land use is positive because aesthetic environment will

not be effected.

Due to opencast mining activities, the landscape will be slightly changed. There

will be no land subsidence as the country is made up of hard rock. The Soil cover in this

Quarry is almost nil and Agriculture is seen mainly in the plains in the vicinity of the

lease area and the mining will not have any impact on the agricultural pattern. Only few

bushes will be cleared to facilitate mining and other related activities and there are no

big trees, which may have to be cut.

3.5.3 Impact of Ground vibrations

Fragmentation of rock by blasting is an important operation in mining project, where hard

rock occurs. Blasting will be done only when it is absolutely necessary, using low

intensity explosives.

Blasting of the Mineral at the proposed Quarry will be done by using Low-density

chemical explosives like ANFO will be used. Sometimes smooth blasting may be done

using silent non-explosive demolishing agents like Acconex.

The ground vibrations caused by blasting will not have any affect as the mining is on a

mound and the vibrations will be minimum and will not be carried too far due to the hard

nature of the rock.

3.6 BIOLOGICAL ENVIRONMENT

There is no adverse impacts are anticipated due to the proposed mining activity on

biological environment. However, with the implementation of the environmental




management measures, there will be improvement in the parameters of biological

environment.

The tree species found with the core zone represent the common type of flora species

along with small shrubs and bushes. Due to mining activities community structure of the

vegetation will not change. Whereas diversity of plant species and food web index of the

area reduced to certain extent.

However, if the proposed reclamation of the mining area and dumped out area using

proper re-vegetation techniques and development of green belt around the ultimate limit

and roadside there shall be an improvement in the species diversity and food web index

compared to the existing level.

3.7 SOCIO- ECONOMIC ENVIRONMENT

3.7.1 No Rehabilitation

The Quarry area does not cover any habitation. Hence the mining activity does not

involve any displacement of human settlement. No public buildings, places, monuments

etc. exist within the lease area or in the vicinity. The mining operations will not disturb/

relocate any village or need resettlement. Thus no adverse impact is anticipated.

3.7.2 Improvement in Socio Economic Status

It will be obvious to assume that the activities of the mining operations have to be

produced some improvements in the socio-economic levels in the study area.

The Lessee will proved employment to local population and it will give preference to the

local people whenever there is requirement of manpower.

The proposed mining activities will provide employment to persons of different skills and

trades. The local population is the largest plausibility among these employees. The

employment potential ameliorated economic conditions of these families directly and

provided employment to many other families indirectly who are involved in business and

service oriented activities. This in-turn will improve the socio-economic conditions of the

area.




3.7.3 Occupational Health and Safety

The Quarry is going to be developed mainly semi mechanized opencast method by using

jackhammer drilling & wire saw cutting & low explosive blasting. No major crushing or

pulverization will be done here. The small-scale mining will not have any ill effects on

the health of labour.

Excessive dust and noise are the chief health hazards for the Quarry. As already

mentioned these causative factors are well within the safety limits and the proponents

will strictly implement the prescribed safety measures. The health of the workers will be

regularly checked and suitable medical facilities should be created on or close to the site.

Highest safety will be ensured in the working conditions of the Quarry.




4. ENVIRONMENTAL MANAGEMENT PLAN

4.1 INTRODUCTION

The mining development in the study area needs to intertwined with judicious utilization

natural resources within the limits of permissible assimilative capacity. The assimilative

capacity of the study area is the maximum amount of pollution load that can be

discharged in the environment without affecting the designated use and is governed by

dilution, dispersion and removal due to natural physio-chemical and biological processes.

The Environmental Management Plan (EMP) is required to ensure sustainable

development in the study area.

This chapter covers the genesis of pollution, the principal sources of pollution, the nature

of pollution, the proposed measures required for meeting the prevailing statutory

requirements of gaseous emissions, wastewater discharge characteristics, noise levels etc.

for environmental management purpose in connection with the mining and mining related

activities in the study area.

This section discusses the management plan for mitigation/abatement impacts and

enhancement of beneficial impacts due to mining. The Environmental Management Plan

(EMP) has been designed within the framework of various Indian legislative and

regulatory requirements on environmental and socio-economic aspects.

Environmental Management Plan giving the environmental protection measures at

Quarry to meet the stipulated norms of IBM/MoEF are as detailed.

4.2 AIR POLLUTION CONTROL MEASURES

The present ambient air quality measurements in the Quarry area are well within the

limits. Due to the proposed production of 39917 cum/year of Road Metal & Building

Stone, there will be marginal increase in dust concentrations.

Mitigative measures suggested for air pollution control are based on the baseline ambient

air quality monitoring data. From the point of view of maintenance of an acceptable

ambient air quality in the region, it is desirable that air quality should be monitored on a




regular basis to check it vis-à-vis the standards prescribed by CPCB and in cases of non-

compliance appropriate mitigative measures shall be adopted.

The following dust prone areas are identified for adopting proper control measures in the

Quarry area.

i) Drilling & Blasting

ii) Excavation

iii) Transportation

The environmental control measures which will be implemented to control the fugitive

dust released from the proposed production are given below:

Wet drilling system & Dust proof

Use of sharp drill bits for drilling holes. The charge concentration of the

explosives will be between 10 – 40 grams per linear meter.

Water sprinkling arrangements such as specially fabricated tankers mounted on

tipper are deployed at Quarry site to control the fugitive dust generation from the

haulage roads.

Regular grading of haul roads and service roads to clear accumulation of loose

material

The blasted blocks (temporary) are wetted by spraying water

Avoiding blasting during high windy periods, night times and temperature

inversion periods.

Excavation operations are suspended during periods of very strong winds.

Massive afforestation for control of dust

Spraying of water on sub grade stacks

The vehicles and machinery are kept in well-maintained condition so that

emission of fugitive constituents is minimized.

Plantation of wide leaf trees, creepers, tall grass around working pit, along roads

will help suppress dust.

Tall trees with an average height of 5 m will be developed all along the boundary

of the lease area to minimize the dispersion of the dust from the mining.




Periodical monitoring of air quality to take steps to control the pollutants.

4.2.1 OCCUPATIONAL HEALTH & SAFETY MEASURES

All the precautions would be adopted to prevent dust generation at site and to be

dispersed into the outer environment. However, for the safety of workers at site, engaged

at strategic locations/dust generation points like drilling, loading and unloading points,

etc., dust masks would be provided. Dust masks would prevent inhalation of RSPM

thereby reducing the risk of lung diseases and other respiratory disorders. Regular health

monitoring of workers will be carried out.

4.3 NOISE POLLUTION CONTROL MEASURES

The ambient noise level monitoring is carried out in and around the proposed Quarry

shows that ambient noise levels are well within the stipulated limits of CPCB.

Noise generation may be for an instant, intermittent or for continuous periods, with low

to high decibels. Periodic inspection and checks of the risk prone areas and equipments

have to be conducted.

To control noise pollution during the proposed mining operations following steps will be

practiced.

The noise generated by the machinery will be reduced by proper lubrication of the

machinery and equipment.

The workers employed should be provided with personal hearing protection

equipment, with earmuffs and earplugs combined, as a protection from the high

noise level generated at the plant site.

The provision of green barrier along the boundary will further reduce the

propagation of noise level generated.

Limiting time exposure of workers to excessive noise.

Speed of trucks entering or leaving the Quarry is limited to moderate speed of 25

kmph to prevent undue noise from empty tippers.




Safety in Blasting:

Care should be taken to evacuate the mining area completely at the time of low explosive

blasting operations. The blasting team should be equipped with all personal safety and

precautionary measure. The following safety measures will be given attention while

conducting the blasting operations.

A blasting SIREN should be used at the time of blasting for audio signal.

Before blasting and after blasting, red & green flags should be displayed as visual

signals.

Warning notice boards indicating the time of blasting and NOT TO TRESPASS

are displayed permanently.

4.4 WATER POLLUTION CONTROL MEASURES

The action program for minimizing adverse affects on water regime is to prevent wash-

off of Quarry water and uncontrolled run-off water during monsoon. Proposed measures

for this are as follows:

Building/extending of retention/toe walls at the foot of the dumps

Construction of Garland drains along the slopes to divert the rainwater course

away from the dumping areas.

Covering of dump slopes with grass plantation to stabilize and prevent erosion.

Plantation of trees along the ridges and slopes.

4.5 LAND ENVIRONMENT

The Dhanbad declaration on Environmental Management in Mining Industry states “It is

imperative that in order to ensure the continued and sustained progress of the mining

industry in India, the environmental dimensions should be integrated into the planning,

design, development, operation and working practices of quarry on scientific and rational

lines, by the Governments and the industry in a mutually reinforcing manner”. The land

related Environmental Management Plan (EMP) has been presented here under two

sections viz., Soil & Water conservation and Afforestation.




Storage and Reuse of Top Soil:

Topsoil removed during clearing of the area for granite extraction shall be stacked

separately to check the erosion of the stacked soil. A retaining wall shall be constructed

all around the topsoil stockyard. Planting of grass and local species etc., are proposed on

the surface of this stack to prevent erosion and to increase the soil nitrogen. As per the

analysis of the soil samples they are found to be basic in nature. During afforestation, it is

recommended to plant fast growing species with good canopy cover and dense leaf

density and some ornamental species to give a good aesthetic look. It is recommended to

sow neem, mahogany plants as soil and climatic conditions are suitable for the growth of

these plants.

Solid Waste Management:

There is no mineral reject or sub-grade mineral in this quarry. However, about 6%

interstitial voids and intercalated waste is anticipated which is computed separately. This

will be utilized for the formation of internal roads and balance utilized to form a barrier

all along the 7.5m buffer zone of the QL applied area to a height of 6.0 m.

About 1633 m3/Year of waste will be generated from this Quarry. The western side of the

area is selected for dump yard for next five years and the waste will be stocked over an

extent of 750 m2

Stabilization of Dumps:

The dumps will be stabilized and shaped trapezoidally. The angle of repose will be in

such a manner that the run off of material will be avoided. The trench will be dug around

the dump to avoid run off. The dumps will be safe-guarded by plantation of trees along

the slope and of the soil cover area. In first five years, it is planned to undertake

plantation of 150 trees per year on the slope of the dump, depending on facilities

available.

Land Restoration/Reclamation:

Land restoration or reclamation of the area is very essential in any mining industry.

Proper measures adopted during restoration will control most of the adverse

environmental impacts of Quarry and also improve the aesthetic beauty of the area. Due

to the Quarry activities in this area the profile of the ground will change due to formation




of pits. At the end of the Quarry operations, the top soil/Mineral rejects will be utilized

for back filling wherever suitable and rehabilitated.

Following steps shall be taken for improving and protecting the environment.

a) Quarry lease area

b) Surrounding the Quarry lease area.

c) Surrounding the statutory buildings

d) On the undisturbed virgin lease area.

Surrounding the Mining area:

The dust generated during the quarrying operations will be carried by wind and will be

deposited over the trees and on the adjacent area around the quarry in the buffer zone. To

filter this dust, a green belt of 10m width shall be developed along the quarry lease area

i.e., around ultimate pit limit, this green belt will also act as sound barrier. In between the

tree saplings, grass and bushes shall be grown. Creation of the green belt around the lease

areas shall be undertaken on priority basis and shall be completed concurrent to Quarry

over a 10-year period.

Surrounding the statutory buildings:

All around the proposed statutory buildings and along the road sides trees shall be planted

in addition to the existing ones which will protect the workers from the noise and dust.

To plant trees around the statutory buildings, the topsoil that is going to be Quarry d from

the area shall be laid to form a strip of 10-15m width and 0.5m thickness.

On the undisturbed virgin lease area:

The undisturbed virgin lease area shall be utilized for afforestation purposes by

developing the area with local varieties. This work shall be done after the cessation of

Quarry operations.

Afforestation Plan:

In every year about 50 mtrs, length of buffer zone will be planted along the boundary on

Eastern and Western side of the area. About 150 Saplings consisting of Neem, Teak will

be planted per year over an area of 50 m x 6m at 3 grid interval.




Apart from the green belts and aesthetic plantation for eliminating fugitive emissions and

noise control, all other massive plantation efforts shall be decided and executed with the

assistance and co-operation of the local community. Based on the community needs the

afforestation would mainly aim at:

a) Protection & Development of Natural Vegetation

b) Protection of soil erosion

c) Plantations of fuel wood blocks to meet the energy requirements.

4.6 SOCIO ECONOMIC BENEFITS

There is positive impact on socio-economics of people living in the villages. The villages

in buffer zone depend upon agriculture. Mining operations in the subject area has positive

impact by providing direct and indirect job opportunities. There will be indirect

employment opportunities in transportation of ore to destination.

4.7 POST PROJECT MONITORING

The Lessee will monitor the environmental parameters as per APPCB/IBM/CPCB

guidelines.

4.8 IMPLEMENTATION OF EMP & MONITORING PROGRAMME

The environment management plan is detailed on the basis of impact assessment. Control

and mitigation measures for the adverse impacts envisaged. As the major environmental

attributes have been confined to the project area alone, implementations of the proposed

control measures and monitoring thereof will be undertaken on the regional basis. The

Lessee will ensure the implementation of the measures within the Quarry area and

carryout efficient monitoring. In order to implement the measures suggested for

mitigating the adverse impacts on the environment, it is suggested to monitor the

environmental parameters regularly.

The details of investments to carryout the regular monitoring and pollution control

measures are given below in table – 2

CONCLUSIONS, SUGGESTIONS/RECOMMENDATIONS

The Mining method proposed as per the approved Mining Plan from Dept. of Quarry s &

Geology is small-scale semi mechanical mining activities without deployment of deep

hole drilling and use of Heavy machinery. Based on the appraisal of the existing

environmental scenario coupled with the assessment studies carried out, it is concluded

that there is no long term environmental impact due to the Road Metal & Building Stone

.quarry at the lease area.

The particulate matter getting airborne from the mining activity gets dispersed in close

proximity itself and settles down early. The noise levels due to the proposed quarry

activity are also not of a higher order that calls for immediate corrective measures. The

ground water analysis indicates that the sources do not get influx of pollutants from the

quarry activity. There is positive socio-economic front in the surrounding region due to

the proposed mining industry. The practice of afforestation scheme is a step in the right

direction towards achieving ecological balance.

Suggestions/Recommendations

Even though there is no perceptible impact from the quarry activity on the environment of

the region, it is imperative that mitigative measures have got to be implemented on full

scale for creating environmental balance and intern maintain the ecology of the region.

The following suggestions/recommendations merit due consideration in this regard.

As no control over wind can be exercised, the frequency of the dust suppression measures like constant watering of the haul roads shall be

practiced.

Afforestation as envisaged in the mining plan is to be carried out so that it not only enhances the green canopy but also stop the spread of dust

particles and air borne pollutants.

Surface water conservation measures and groundwater recharge be given high priority.
