of Pollution) Act, 1974: Area is not falling under Water act, 1974

4.2 Environmental Impact Assessment:

Land Scape: The mining lease area is being used for mining, pitting etc., therefore the

landscape will be altered.

4.2.1 Air quality: During mining and drilling dust will raise, due to which the air will be polluted

and the quality of air will be decreased.


2018

17

4.2.2 Aesthetic Environment: There is no aesthetic environment prevailing in the area.

4.2.3 Water quality: The seepage water quality will not be polluted due to hard strata and no

mineral coming across the water course. Total water will be pumped out to the surface in

time to time.

4.2.4 Noise levels: The drilling, blasting are rarely used, the noise will arise by movement of

vehicles. The noise in this mine is negligible. The lessee will maintain the machinery to

keep in good condition, so the noise will be under control. However for safety measures the

lessee will provide ear-plugs to the mine workers.

4.2.5 Vibration level: In this area the mineral is tenable to easy mining, therefore, the blasting

will be done seldom. Hence, the vibration is negligible, however less explosive will be used

in shot hole.

4.2.6 Water regime: The ground water is not contaminated due to mining.

4.2.7 Socio-economics: The mining lease area is 0.5 km away from the arrest village Kalichedu

and the proposed mining activity will fetch employment to the local people which will

improve socio-economic condition of the surrounding villagers.

4.2.8 Historical monuments: No historical monuments are existing in and around the mine

within the radius of 1.5 km

4.2.9 Environmental Management Plan:

Temporary storage and utilization of top soil: In this area the soil will be mixed with

waste and there is no top soil.

Year wise proposal for reclamation: In this 3 years scheme period it is proposed to

undertake opencast mining, therefore, reclamation is not proposed in this mine.

Waste generated: During production in 3 years period it is anticipated that about 8,431 MT

i.e., 3374 m3 of sub graded minerals will be generated from the open cast workings. The

waste will be dumped on existing waste dump.


2018

18

Afforestation: The lessee intends to undertake afforestation with eucalyptus plantations,

over an extent of 510 m2area during these three years production along North side of lease

area.

Stabilisation and vegetation of waste dumps: Terracing and garland drains will be

developed around the waste dumps.

Measures to control the erosion and sedimentation of water course:The water course as

such does not exist in the mining area. Therefore erosion and sedimentation on water course

will not arise.

Protective measures for ground vibrations / air blast caused by blasting:It is proposed

to conduct shot firing carefully. Therefore vibration is negligible.

Measures for protection of historical monuments and for rehabilitation of human

settlements likely to bedisturbed due to mining activity: No historical monuments are

existing in and around the mine within a radius of 2 km.

Socio-economic benefits arising out of mining: The local village people are getting work

in mine and the socio-economic benefit will reach common workmen in and outside the

mine directly or indirectly. Due to inflow of money from mines, the business activity will

be increased, in such a manner socio-economic benefits will occur.

4.2.10 Processing:

In this mine the proponent is supplying the mineral without processing to consumers. Therefore,

mineral processing is not being done in this mine.

4.2.11 Infrastructure and services and construction activities:

The proponent has provided office-rest shelter complex outside of the ML area in extent of 1000

m2. The lessee is providing drinking water supplied by village panchayat, first aid facilities to their

workers and private medical practitioner. They have developed very good plantation around their

buildings and created good atmosphere.


2018

19

Costing:Estimation of project cost:

Total expenditure per year: Rs. 60 Lakhs

4.2.12 Marketing:

Lessee is having good market for mica, quartz and feldspar. Mining is economically feasible as per

current market analysis.

4.2.13 Other factors:

The mining lease is far away from the village and having congenial condition to work. The lessee is

paying royalty, rents and other taxes applicable to the mining industry. The mining area is

surrounded by few villages; the laborers are attending mining work from surrounding villages.

III. CONCEPTUAL MINING

For any mine conceptual mining plan amounts to, for-seeing in totality and planning for mining and

related activities throughout its life span. Apart from physic-chemical and mineralogical parameters

which form primary basis for compilation of conceptual mine plan, other factors such as grade of

sub-grade ores, marketability and norms laid down by government agencies from time to time play

prominent roles. With, ever increasing and changing needs of humanity, coupled with

technological advancements, sub grade ores of the date become marketable ores in future. In this

regard, preparation of ideal conceptual mine plan or any mine is difficult and such plan period

prepared remains acceptable only under given circumstances. It shall be ensured that by the end of

mine plan all usable ore minerals will be excavated to the economic al limits and lease area is

reclaimed to the extent possible. There shall be positive contribution to the environment and socio-

economic development of the region.

Ultimate Pit Limit:

The ore body is considered for opencast workings upto a depth of 8m. The ultimate pit limit is

fixed at this level keeping pit slope angle of 80 deg.


2018

20

Mine Development:

For getting feldspar, quartz and mica, the over burden and side burden must be removed as a part of

development. The removed waste will be dumped outside the pit in a predetermined area. The

waste dumps will be covered by afforestation in future.

Life of Mine:

The reserves have been estimated afresh as on 10.01.2015 based on geometry of ore body as

exposed in quarry due to mining activity. Lease area is divided into an existing pit No. 2 to 3 and

non-operative pits in other part of ML. Exploration not conducted in other parts.

The total Mineable Reserves = 25,150 T

V. MINING

5.1 Salient Description of present mining method

The pegmatite ore body will be worked by opencast mining method. Mining operations will be

commenced from higher elevation to lower elevation. Rock is hard and requires blasting.

Compressed air driven jack hammers are used to drill holes of 25 mm to 30 mm diameter to depth

of 1.5 m to 3 m. Holes are drilled in a pattern so that after blasting benches are formed having

height of 3 m and width of more than 3 m. Broken rock is manually sorted for picking saleable

Mica, Quartz and Feldspar and then transported to the stock yard. The sub graded material is

transported to dump yard. The mining machinery and equipment proposed to be deployed in mine

for different mining operations during the ensuing scheme period are described in table below:

9.1 Water quality management:

One small dry Nala exists in lease area and no rivers, tanks and other potential water

sources in area. During rainy seasons, rain water will flow through Nala of the area.

No impact of ground water course during the mining

9.2 Water Environment Management:

Proposed mine is to extract scrap mica from sumps, hence no effect on water regime

or water bodies. Requirement of water from plantation and other need is met by

adjacent underground mine belonging to same lessee.

9.3 Air quality management:

The contribution of fugitive dust generation is very marginal within the ML area

created by tippers movement. Handling of ore and waste to stock yard and waste

dump respectively are being done by manual means only.

Air pollution control measures:

1. Haul roads will be compacted and water sprinkling arrangement will be

provided by mobile water tankers to suppress fugitive emissions.

2. Water sprinkling in dump yards and handling points and other potential dust

generation areas.

3. Mine has only 1 diesel operated compressor consuming 30 lts. Of diesel per

day. Nozzles are well maintained. Pollution is in negligible level.

4. Mine ventilation systems exhausts at 1375 cum per minute from mine.

Explosives used on an average are only 22 to 3 kg/day for open cast mining.


2018

26

5. Combined effect of diesel consumption and explosives used will not be

significant contributor to air pollution. Air from mine is free from dust

particles as wet drilling is practiced in mine.

9.4 Waste Management:

Sub grade material or waste generated is given as 8,431 MT per annum and

comprises pegmatite schist, schist and micaceous material. Total waste of 24,088

Tons (9635CuM) will be handles in three years of mine scheme period producing

1204 T of scrap mica of waste consists of host rocks in likely to be generated. It

is proposed to dump waste on existing dumps.

9.5 Top soil management:

1000 M3 top soil generated during current scheme and will be used for

plantation.

9.6 Tailing Dam management:

Surface water:In and around lease area now ells and tube well exists. Surface

water will not be interfered by mining activity since source of Nala water flow is

200m away from opencast workings.

Ground water:Source of underground water into this mine is natural percolation

from strata. It is being pumped out regularly. It is being used for watering the

plantation without any adverse effects.

9.7 Afforestation:proposed year wise plantation in this scheme period is given below

X. GREEN BELT DEVELOPMENT

The development of greenbelt in the peripheral buffer zone of the mine lease area

will be undertaken well before the starting of the mining activity.

Green Belt has been recommended as one of the major component of Environmental

Management Plan, which will improve ecology, environment and quality of the

surrounding area. Plantation will be done along the haulage roads and the unused

area in the ML area will be developed with green cover. Suitable advice on this

plantation activity will be consulted with the local Forest Department along with

measures to ensure good survival rate.

Concepts of Green Belt Development

The concepts of Green Belt Plantation scheme are

1. Nature of Pollutants

2. Emission Levels

3. Maximum Impact zone

Criteria for selection of species

Species to be selected should fulfill the following specific requirements of

the area

- Availability of seed material

- Tolerance to specific conditions or alternatively wide adapts ability to eco-

physiological conditions.

- Rapid growth

- Capacity to endure water stress and climatic extremes after initial

establishment

- Differences in height, growth habits

- Pleasing appearance

- Providing shade

- Ability of fixing atmospheric Nitrogen

- Improving waste lands.


2018

DESIGN OF GREEN DEVELOPMENT

The greenbelt shall be developed around the plant to act as a sink for pollutants,

attenuation of noise levels and improvement in aesthetic quality of the plant. The

following criteria shall be adopted in the design of greenbelt:

1. Generally fast growing trees should be planted as otherwise it will

take many years for other types of trees to attain their full height.

2. Trees will be planted along the road side in such a way that there is

no direct line of sight when viewed from appoint outside the foliage

perimeter.

3. Trees growing up to 10 m or more in height with thick perennial

foliage should be planted around the plant.

4. Sensitive species such as magnifier indica should be planted in

patches along the entire greenbelt to work as an indicator of

pollution.

5. Trees shall be planted staggeredly in each row (minimum three rows

encircling the perimeter of the plant).

6. Tree trunk being free foliage up to a height of 2 to 3 m, it is advisable

to grow shrubs in front of trees to give coverage to the open portion.

7. Greenbelt will be developed all around the plant area with a width of

10 m.

8. Greenbelt will be developed around the plant except wherever

buildings and other structures.

9. Local Plant species will used for development of green belt.

XI. SOCIO-ECONOMIC ENVIRONMENT

This mining project will contribute in the development of economic status of the region and

indirectly provide a platform for many businesses; both on small and big scale. These

include direct employment and indirect employment in transportation, vehicle/Equipment

maintenance etc. The company management would give preference to local people through

both direct and indirect employment. There will be generation of indirect employment due

to the proposed activity like transportation etc.

XII. SAFETY AND ENVIRONMENT

Complete evacuation of the mining area at the time of blasting will be followed strictly. The

proponent will provide all necessary provisions stipulated under the Factories Act and

mines act. In addition a safety committee will be formed and manned by equal participants

from Management and Workers.

The management firmly believes in the concept of safety and environmentally

sustainable growth. The authorities and staff are very much concern in

Environment issues.

The management is going to develop scientifically designed green belt around the

premises to mitigate air and noise pollution impacts on the surroundings.

The management proposed to monitor ambient air as per APPCB guidelines.

All the employees are provided with personal protective equipment such as helmets,

hand gloves, safety shoes, goggles and apron as per their place of work.

The management will provide safety training to all employees periodically and

regularly.

Drilling Precautions:

Wet drilling adopted

Use of sharp drill bits, delivery of compressed air at optimal pressure and proper

maintenance of compressor and drilling machine.

Provision of ear plugs/ear muffs to drillers.

Blasting Precautions:

Proper charge per delay will be regulated

Millisecond delay detonators will be used to reduce fly rocks vibrations and noise

control. Streaming column and each blast will be planned, supervised and executed

by expert staff

Blasting shelters for blasters will be provided. Safety precautions as per M.M.R –

1961 and as per suggestions of explosive manufacturer will be strictly followed.

Applicant will obtain portable explosive license after grant of mining lease.
