ENVIRONMENT MANAGEMENT PLAN

1.0 IntroductionThis report discusses the management plan for mitigation/abatement of adverse

environmental impacts and enhancement of beneficial impacts due to mining. The EMP has

been designed within the framework of various legislative and regulatory requirements on

environmental and socio-economic aspects.

M/s. C. V. C. Mining Company proposes to conduct semi mechanized underground method

mining for Mica, Quartz and Feldspar in an area of 4.33 Acres or 1.752 Ha located in Survey

No. 109, 110 & 111, Talupuru Village, Sydapuram Mandal, SPSR Nellore District, Andhra

Pradesh. In principle grant of quarry lease of extension of time notice was issued by the

Department of Mines and Geology, Government of Andhra Pradesh vide Notice No.

21290/R3-1/2016 dated 01.10.2018. Mining Plan was approved Deputy Director of Mines and

Geology, Guntur vide Letter No. 3355/MP/Quartz/NLR/2018 dated 16.10.2018. Proposed

production of Mica @ 375.95 TPA, Quartz @ 198 TPA and Feldspar @ 990 TPA. Capital cost

proposed for the mining will be approximately Rs. 40 Lakhs. As per the ADMG letter, the total

cluster of area within 500m surrounding from the ml boundary is 25.357 ha.

M/s. C. V. C. Mining Company is conscious of his environmental responsibility towards the

society in minimizing the pollution load due to this project and accordingly decided to carry

out the Environment Management Plan. The objective of preparing environment

management plan is to delineate effective measures to control and to mitigate the

environmental pollution. This report presents the environment management plan, detailing

the environmentally sound technology and the measures needed to contain and mitigate the

anticipated environmental impacts due to the project.

1.1 Uses of mineral

Quartz containing 99% plus Silica is used in glass industry. This is also used in electrical

industry for making semi conductors. Feldspar is mainly used for ceramic and isolators

manufacturing units. Mica is used in paints as a pigment extender and also helps to brighten

the tone of colored pigments and also used in the electrical industry the same as thermal

insulation, and electrical insulators in electronic equipment.

1.2 Mining Technology

The mining operations will be carried out by the underground mining method with semi



mechanized by adopting of drilling and blasting with help of jack hammers. The accessing to

the mine through the existing shaft and the winzes will be made at a spacing of 15-30m to

explore the ore body and level interval between two adjacent levels will be 6-8m.

1.3 Cluster Details

Reason for submission of the present project and background information:

The MoEF & CC through its legislation has issued a notification No. SO 141(E) dated 15.1.2016

through which it issued cluster guidelines for the purpose of obtaining Prior Environmental

Clearance for the Mines. As per that SO every mine shall obtain prior EC for its operations

and also EC for the entire cluster incase it falls in the definition of cluster. Accordingly the

present cluster falls under purview of definition of cluster as per the SO. Hence the present

EMP for the whole cluster is being prepared. As per the S. O. 2269 (E) notification dated

01.07.2016 and the ADMG letter, the total cluster of area within 500m surrounding from the

ml boundary is 25.357 ha. The details of Cluster projects as per Mining Plan are given below.

2.0 Topography

The quarry lease area is part of agricultural land with gentle slope due NNE.

3.0 Regional Geology

The Nellore Mica belt is about 110 Km long from Vinjamoor in the North to Ozili in the South.

The width of Mica belt varies from 10 Km to 30 Km and the depth of Pegmatite varies from 10

to 350m (As per the information collected from the existing underground mines of Mica). The

dips of Pegmatite lenses are 45° to 80° towards West. This Nellore Mica belt is divided into 6

zones as detailed below

Nellore Mica Belt

1 Northern Pennar on the North most portion2 Tatipatri - Prabhugiripatnam3 Podalakur - Talupuru4 Kalichedu5 Utukur - Sydapuram6 Chennur – Kadivedu on the south most portion

The mining lease applied area is in the 3rd zone namely Podalakur-Talupuru. The granites and

pegmatite have intruded into schists of Kandra Volcanics, which contain Quartz, Biotite and

Hornblende Schists. Under favorable conditions, Muscovite books of commercial grades have

formed by intrusion of pegmatite into schists. Hundreds of Mica Mines were worked in the

Nellore Mica belt. The available information is Rubby Mica was found in 4th & 5th Zones and

green mica was found in other zones.

4.0 Geology of the area

A pegmatite lense is outcropping in the mining lease applied area. The dimension of the

pegmatite on surface is 25m wide and 50 m long. The country rocks is hornblende biotite

schist exists along the western margin of the pegmatite trending in NNE.

5.0 Details of Exploration

The area is previously worked by the previous applicant. One inclined shaft, one vertical shafts

were driven in North and Southern parts with to entry drives from levels at 12m, 18m, 25m,

37m and 46m were made to reach 5 levels at RL 188m, RL 182m, RL 175m, 163m and RL 154m.

The major concentration was made to extract the mica mineral only during that period and

feldspar zone was not tapped. A large dump of Mica pegmatite is existing in the area over an

extent of 8731 m2 with 2 to 2.25 m height. Total volume = 8731 X 2 = 17462 m3. Now, it is fresh

mine and we are waiting for statutory clearances from concerned departments.



6.0 Estimation of Reserves

The estimation of Mica, Quartz & Feldspar reserves is made by using the cross sectional

method the ore body. One cross section X-X1 was drawn perpendicular to the strike direction

of the formation to estimate the reserves. The ore zone is established upto 46m BGL and

probable resources are measured to the depth of 18m below the proved reserves. The bulk

density considered as 2.5 t/cum and recovery is taken as 10% of Quartz, 50% of Feldspar and

5% of Mica mineral. Geological Reserves calculation was given below in Table 1.3.

7.0 Mining Method

The mining operations will be carried out by the underground mining method with semi

mechanized by adopting of drilling and blasting with help of jack hammers. The accessing to

the mine through the existing shaft and the winzes will be made at a spacing of 15-30m to

explore the ore body and level interval between two adjacent levels will be 6-8m. In this

underground mining methods are as follows:

Entry into the deposits is by two inclined shafts along apatite vein at 60O from the

horizontal and with x – section of 2.5m x 2.2 m.

Drives cross cuts and winzes of 2.2 m x 2.0m cross section are developed to block the

mineral.

10 HP electrical winch and bucket of 0.6 tons capacities are used for hoisting the broken

material from the underground mine faces.



Material broken from the mine faces is moved to the hoist chamber through manually

pushed tubs on rails laid on the drive floors.

Wooden props are used to support local loose patches.

Cap lamps will be used by the workers

Underground layouts are as follows:

The method of mining is underground mining method. There are old workings up to a depth

of 52 m. One vertical shaft is available at South upto 52 m depth and a inclined shaft in South

side with two inlets are present. The present workings have established the presence of

pegmatite. Several cross cuts which are proposed to confirm width of pegmatite and content

of minerals are planned. Thus by the end of five years, the pegmatite will be explored

/exploited up to 52m depth and width will be established. Inclined Shaft will be extended

upto 125 m RL (95 m).

System of Drilling & Blasting:

The pegmatite and schist are hard and compact rocks. Excavation is done by drilling and

blasting. The cross sections of vertical shaft is 2.5 m. Diameter, that of winze is 2.2 m and that

of level drives and cross cuts is 2.2/2 m. The number of holes required for shaft, winze and

levels are 42, 42, 48, 54 & 64 respectively. Model Burn cut design for underground drilling and

blasting this formula is followed in the small mines viz Mica pegmatite which are of 2.2 m

(Height) and 2m(Width) with proportionate measurements and drill hole length will be 0.75m

each with 32mm dia. The alternate holes are charged with explosives the sequence of delay

occurs from centered 4 holes and the surrounding are fires with few seconds/ milli seconds

delay. The drilled holes are blasted by using slurry explosives and short delay detonators to

control vibrations. All precautions prescribed under MMR 1961 will be followed. The average

quantity of explosives used as 2 Tons /1 Kg of explosive. The requirement of explosive for

shaft sinking is 9 Kgs for 1 m progress, winzes is 7 Kgs for 1m progress and 5 Kgs for 1m

progress in levels. The total requirement of explosives for total annual volume of 1980 MT,

development work is calculated for five years

Mine support:

The Hanging Wall and Foot Wall consist of Hornblende schist’s and pegmatite itself is strong.

Normally supports are not required. When kaolin is present, the pegmatite becomes soft and



friable. That portion of mine work will be supported by post and bar method. The supporting

material is timber for temporary support and steel for permanent support.

Underground transportation:

Mica (Scrap and books) will be handpicked from the blasted material in the mine and carried

on head loads to the surface for dressing in Mica Shed. The rest of the broken rock will be

loaded manually into half ton capacity level tubs and trammied on rails to the shaft bottom

from where, the material is lifted by hoist to the surface and emptied into level tubs, for

further coarse of action i.e. sorting and sizing etc

Mine ventilation:

30000 m3/min capacity ventilation plan will be installed as forcing fan at surface at the mouth

of man way with proper construction. The air is forced through man way and the return air

will be through the vertical shaft which is second outlet. Necessary ventilation stopping will

be constructed at required places so that short circuiting of air is not allowed. The air will be

forced so that every person employed in the mine will be supplied 6 m3 for minute, as well as

dilute all the gases generated in the mine to permissible limits.

be 0.75m each with diameter of 32mm. The alternate holes are charged with explosives and

the sequence of delay occurs from centered 4 holes and the surrounding are fired with few



seconds/milli seconds delay. The drilled holes are blasted by using slurry explosives and short

delay detonators to control vibrations. All precautions prescribed under MMR 1961 will be

followed. The average quantity of explosives used as 2Tons/1 Kg of explosive. The

requirement of explosive for shaft sinking is 9 Kgs for 1m progress, winzes is 7 Kgs for 1m

progress and 5 Kgs for 1m progress in levels. The total requirement of explosives for annual

production of 1980 MT, development work is calculated for five years

Inclined shaft/winzes/V. Shink =64m x 7kgs = 448kgs

Levels =494m x 5kgs=2470kgs

Cross cuts =178m x 7kgs = 1246kgs

Total Requirement = 4464kgs

Allowing for losses on miss fire etc 10% is taken over and above this. The total requirement is

4580.4 Kgs.

The average yearly requirement: 916.08 Kgs

The Lessee will apply for licensed Explosive Magazine. The required explosive will be drawn

from that magazine. Alternatively engages a licensed blasting contractor for carrying out the

drilling and blasting (which practice is in vogue in small mines in the area).

9.1 Drilling & blasting safety

Adequate competent persons will be provided to make the blasting operation completely

safe.

Vibration will be managed by delayed blasting pattern, proper stemming and control

charge per hole.

Adequate sirens and signal boards will be given in addition to posting guards at strategic

points.

All terms and conditions laid down in the license shall be compiled

No dangerous/inflammable articles shall be taken by the personnel employed for blasting.

12.0 Use of Mineral

Mica:

Mica is having high insulation property. One mill thick Ruby Mica can stop 10000 volts. The

mica will not deform even at very high temperature. This is an important requirement for

space machinery. Most of the mica produced in India is exported to developed countries. Scrap



Mica is utilized in forming various products like Micanite Sheet, Mica Tapes & Mica powder.

They are used in electronic machinery. Green Mica is present in the mining lease applied area.

Feldspar:

Feldspar containing 12% + Alumina is used in Ceramic Industry and Sanitary Ware. Electric

Ceramic Insulators for over head lines are made from Feldspars. This is used in India and

export demand is available.

Quartz

This is used in Glass Industry. High quality quartz is used to make semi conductors which are

essential for electronic industry. The demand is available for Quartz in India and outside.

13.0 Water requirement

Water requirement of 5.9 KLD is mainly for drinking purpose, domestic purpose, green belt

maintaining and for sprinkling on Mine haulage roads the water shall be drawn from nearby

village. The domestic waste water shall be sent to septic tank followed by soak pit. The water

requirement is presented in table 1.7.

Total 5.914.0 Environment Management Plan

Environmental protection is an issue that no organisation can neglect and hope to survive.

The byproducts of civilization are being dumped upon the environment to a degree that the

environment finds difficult to assimilate. The key to the success of the integrated approach to

pollution prevention and control is the management and operation of the organization.

Effective committed management delivers a successful operation. As total commitment to

the environment, not just for compliance with legal or regulatory compliance will be the

essence of environment management. Many companies have recognized the benefits of

implementing an effective environmental management system. Environmental management

plan can be effectively implemented to mitigate the pollution levels by observing the

following:

a. Pollution will be prevented or reduced at the source



b. Pollution that can not be prevented will be recycled in an environmentally safe manner.

c. Pollution that can not be prevented or recycled will be treated in environmentally safe

manner and

d. Disposal and other releases into the environment will be used only as a last resort and will

be conducted in an environmentally safe manner.

The proposed project is Mica, Quartz and Feldspar mine. The mine owners are aware of the

adverse impacts due to the mining activity and propose to initiate a number of measures for

the environment protection within the mine area and in the surrounding areas. The company

has a stated environmental policy of ensuring regulatory compliance with respect to the

statutory laws and regulations and those periodically issued by the Ministry of Environment,

GOI, New Delhi, CPCB, New Delhi and A.P Pollution Control Board, Hyderabad.

14.1 Sources of Pollution and Control Measures

The sources of pollution from the proposed activity are mainly from Mining, Drilling, Blasting

and transportation of mineral.

14.1.1 Noise Generation

The major source of noise pollution is due to drilling, machinery and Blasting. Protective

equipment to reduce the noise levels like ear muffs and other protective devices will be

provided to the staff working near noise generating sources. The greenbelt development will

also help in the reduction of noise levels outside the mine. Noise barriers in the form of trees

are provided to attenuate the noise levels. Training would be imparted to mine personnel to

generate awareness about the damaging effects of noise. Proper maintenance of the

equipment will also reduce the noise. The noise produced due to machinery operation and

vehicles are negligible.

15.0 Occupational Safety and Health

Health and safety aspects of the mine will be taken care off as per the World Bank (WB)

guidelines on open pit mining. The guidelines provide the detailed information on the aspects

that are required to be taken into account for maintaining proper health and safety issues.

The workers continuously exposed to dust will be provided with some protective devices like

dust mask to prevent respiratory disorders. The workers continuously exposed to a high noise

will be provided with ear muffs/ earplugs. Green belt in and around the mining area will be

developed to attenuate noise and dust impact. The blasting carried out in the mine area will



be carefully planned and executed under the supervision of a responsible officer, to avoid any

accidents. Drinking water supply for the employees will be provided by the project authority.

The standard of the drinking water will be per WHO guidelines. Periodical training programme

to inform the employees about their task, associated risk, and safe working practices will be

undertaken. Training will also include information on accident prevention, proper control and

maintenance of equipment and safe material handling practices. Proper fencing will be

provided around the mine pits and waste dump areas to prevent the accidents and cattle felt.

A regular monitoring of the Occupational Health and Safety will reduce the chances of

accidents in the mine. Records of job related accidents and illness should be maintained.

These information’s will be reviewed and evaluated to improve the effectiveness of

Environmental Health and Safety programme.

15.1 Occupational Safety and Health to Control Dust Inhalation

Dust is expected to be generated during mining and dose not effect the environment.

However while drilling, wet drilling will be practiced. It is a small scale mining activity and not

much vehicular movement is expected. Water sprinkling arrangement will be provided to

reduce the dust emissions and green belt will be developed around the pits to reduce dust

generation and noise generation. Trucks are covered with tarpaulin during transportation and

overloading of trucks will be avoided to prevent dust generation. PUC certified trucks will be

used for transportation of mineral and waste within the lease area. Greenbelt will be

developed with tall trees around the waste dump area to prevent dust emission. All the above

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

outside environment. However, for the safety of workers at site, engaged at the strategic

locations/dust generation points like drills, loading & unloading points 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.

15.2 Occupational Safety and Health to Control Exposure to Noise

Blasting will be done using safety fuse using slurry explosive to reduce vibrations, and the

amount of explosive used will also be less at a time. There will not be heavy earth moving

machinery which may create some noise pollution. Thus the vibration and noise will be well

controlled within permissible limits. Trucks are kept in switch-off mode while loading and the



speed of the trucks are restricted to limited speed of 15-20kmph to prevent the noise

generation and safety purposes. To protect the workers from exposure to high levels of noise,

following measures would be adopted; by provision of protective devices like ear muffs/ear

plugs to workers who cannot be isolated from the source of high intensity noise, reducing the

exposure time of workers to the higher noise levels by shift management.

15.3 Control of Ground Vibrations & Fly Rocks Boulder

In this area the applicant proposes to deploy blasting with less quantity of explosives. There is

going to be hardly any impact on surroundings, as there are less blasting and intended to use

low power explosives in this mine. It is a small scale mine and only limited No. of holes are

blasted. Ground vibrations due to blasting and its impact on various mine structures, should

be studied in details when the mine becomes operational. General measures to reduce

ground vibration & fly rocks resulting from blasting are given below:

Peak particle velocity or ground vibrations for safety of nearby structures and residential

buildings should be well within 1 mm/sec;

To contain fly rocks, stemming column should not be less than the burden of the hole, and

the blasting area should be muffled;

Blasting should be carried out in the daytime, as during the night time the sound intensity

becomes higher;

Blasting should not be carried out when strong winds are blowing towards the inhabited

areas;

Each blast should be carefully planned, checked, and executed under the supervision of a

responsible officer. Blasting data/observations should be recorded; and

As per the mining plan, in order to ensure slope stabilization, controlled production blasting

shall be adopted to avoid tension cracks and back breaks. Such cracks may get filled with

water, which reduces the stability of excavated slopes and the angle of slopes.

16.0 Water Quality Management

Since there is no chemical discharge either from the mine or from the processing mine, there

will not be water pollution. The proposed mine workings will not touch the ground water

aquifer and no change in quality of water.



16.1 Water Resources

There are no wells or springs in the area. Mining operations will be carried on surface. Hence

there will not be adverse effect on ground water due to mining. The daily water requirement

for the mine operations would be approximately 5.9 KLD. Water sprinkling on mine haulage

roads etc shall consume 1.3 KLD. Wet drilling operations consume about 1.0 KLD. For green

belt development water consumption is about 0.6 KLD. Domestic purpose is about 3.0 KLD.

The water is to be sourced from nearby village through tankers. The generation of

wastewater from domestic sources is expected to be approximately 2.4 KLD, which will be

sent to septic tank followed by soak pit.

16.2 Water Management

Following measures will be adopted to mitigate the impact on the water resources:

The blasting activities will have to take care on the sinkholes, cracks and fissures in the site

activities.

During excavation and drilling activities effort must be taken to avoid face collapse at these

cracks and fissures.

To prevent surface water contamination by oil/grease, leak proof containers shall be used

for storage and transportation of oil/grease. The floors of oil/grease handling area will be

kept effectively impervious.

To prevent degradation and maintain the water quality during rainy season, adequate control

measures should be adopted to check the mine run-off into the natural streams. Following

control measures are proposed to be adopted.

16.3 Catchment Area Treatment Plan

A catchment area treatment plan has been developed keeping in mind the results of the

hydrology/ hydrogeology study as well as the climate data. As there are no perennial water

sources running on or through the site, the mine water discharge is limited to the monsoon

season only. To keep water from entering the mine during this period, a garland drain will be

developed, which will bend to guide the water to the nearest natural surface drain. In terms

of water quality, good mining practices are planned, additionally the natural state of

surrounding areas, should ensure that rain water run-off from the mine does not contain any

toxic elements. As the site has no overburden or excess clay, potential discharge of sediments

is quite limited and any residual clay or limestone particles which are washed down will be



captured by a sump located at the lowest bench. The sump will be cleaned regularly and

discharge water monitored consistently. If required, based on monitoring, an additional catch

pit can be located at the main garland drain. The sump proposed in the bottom bench will be

designed based on the peak discharge and will be expanded over a period of time to

accommodate the increasing quantum of water discharge. The garland drain shall be

provided surrounding the mine area. Check dam and salutation pond need to be constructed

of appropriate size to arrest silt and sediment flows from soil and mineral dumps. The water

so collected should be utilised for watering the mine area, roads, green belt development etc.

The drain should be regularly desalted and maintained. The garland drain (size, gradient and

length) and sump capacity should be designed keeping 50% safety margin over and above the

peak sudden rainfall and maximum discharge in the area adjoining to natural drains. Sump

capacity should also provide adequate retention period to provide proper settling of silt

material. The surface water around the mine, and infrastructure will be regularly tested and

appropriate control measures adopted in case of any pollutant is detected above the

prescribed limits.

17.0 Waste Management and Dump area

During these five years period about 2856.7 Tons of waste will be produced. This waste will

be dumped over an area of 0.873 ha within the lease area.

18.0 Land Management

Land degradation is one of the major adverse impacts of underground mining.

19.1 Land Reclamation

No reclamation is proposed during the plan period.

19.2 Soil Conservation Measures

Top soil is not expected in this mine. To prevent soil erosion and wash-off of dump-fines from

freshly excavated benches and dumps following measures shall be adopted:

Garland drains will be provided around the mine wherever required to arrest any soil

from the mine area being carried away by the rain water;

Toe drains with suitable baffles will be provided all along the toe of the soil dumps to

arrest any soil from the dump slopes being carried away by the rain water;

Loose material slopes will be covered by mineation by making contour trenches at 2 m

interval to check soil erosion both due to wind and rain;



19.0 House Keeping

Proper house keeping and cleanliness will be maintained in the infrastructure facilities. Wet

mopping will be adopted to conserve water. Sign boards will be provided in the work areas

and the road and building highlighting the safety and occupational aspects.

20.0 Transport Systems

Nearest town is Gudur located at a distance of 22 Km from the ML area in SE direction.

Nearest railway station is at Manubolu at a distance of 20.8 km from the lease area in SE

direction. Nellore to Rapur main road is passing at a distance of 3.0 km in North direction.

Duggunta to Kalichedu road is passing at a distance of 0.15 km in NE direction. Cart Road is

available from the main road to the ML area. Number of truck trips will be 1 per day. When

the material is sold to the parties, it is expected to lift the minerals by their own vehicles or

hired ones from the mine. Sufficient parking facilities will be provided for vehicles loading and

unloading of material. Safety signs will be displayed inside and outside the mine to avoid road

accidents.

21.0 Environmental Greening Program

Environmental greening program is an important component of the Environment

Management Plan and is an imperative requirement for any major industrial activity, as per

the guidelines issued by the Ministry of Environment and forests, Govt. of India.

Conceptualization, design and implementation of the proposed activity, taking into account

the specific requirement of the proposed mining activity and the site conditions are

presented. During this plan period about 150 saplings of local plants will be planted over an

area of 0.075 ha in the lease area. A thorny fencing shall provide to guard the trees from the

cows and goats, necessary manpower shall be arranged for vigilance. The environmental

greening program as designed comprises the location and development of a shelterbelt and

Afforestation in about 0.075 Ha. The shelterbelt will contain species, which act as

windbreakers so that the environment within the mine is contained; the planting of different

species in rows is envisaged in general in the greenbelt.

22.0 Socio-economic Environment

The project provides an opportunity for the local people to get employment directly or

indirectly and helps in the upliftment of the socioeconomic status of the area. The proposed

project would generate an employment of 66. The management will involve in social activities



of stakeholders/surrounding community by planning the betterment of neighboring social

conditions through awareness and welfare programs to ensure an improved relation, useful in

the long run. Many of the beneficiaries of such programs will include own employees as well.

The goodwill of the local populace can never be ignored. It is proposed to supply drinking

water and medical facilities to the villagers. The channels employed may vary either through

direct contact or by means of local organizations. Another important facet of social

environment identified by the project proponents is a green appearance; hence the

management will develop a green belt towards aesthetic beautification as the same is

necessary to be considered as a responsible, social neighbour.

23.0 Disaster Planning
