2.5. Geology of the precise area

The proposed area of contain light to dark blue color Charnockite mainly

composed of Quartz and orthoclase feldspar with some ferromagnesian minerals. The

term charnockite in this sense is consequently not the name of a rock, but of an

assemblage of rock types. The assemblage is connected by origin, the differentiation of

the same parent magma. The banded structure which these rocks commonly present in

the field is only in a small measure due to plastic deformation, but is to a large extent

original, and has been produced by flow in a viscous crystallizing intrusive magma,

together with differentiation or segregation of the mass into bands of different chemical

and mineralogical composition.

The Charnockite is part of peninsulur gneisses, a high grade metamorphic rock of

Western Ghats. Massive formation of bluish gray colour of charnockite is also called as

blue metal or rough stone. It is suitable of construction purposes because of its high

strength, colour, high density, low porosity etc. The trend of formation is parallel to

Western Ghats and dips steeply.

Project Description

3.1. Reserves Estimation

3.1.1. Method of Estimation

The geological and Mineable reserves are estimated by cross-sectional Methods

up to a depth of 38m from above the mean sea level. Recovery of Charnockites is taken

as 95% and 5% shall be fines, mining losses and safe benches

3.1.2. Computation of reserves

The geological resources is estimated by cross sectional method is as 280079m3 of

rough stone up to a depth of 38m from the surface. Due consideration is given to depth

of mining, recovery and safety barriers etc. A detail of estimation of geological reserves

is given in Plate No.III and the mining plan.

3.1.3. Conceptual Mining Plan (Final Mine Closure)

The ultimate pit size is so designed based on certain practical factors such as the

economical depth of mining, safety zones followed, available area for mining. The

ultimate pit size of the mine in bench-wise is calculated as in table 3.3.

Table 3.3.: Ultimate Pit Dimension

Bench Mineral /

overburden Length(m) Width(m) Height(m)

I Gravel (TBI) 67m 128m 2m

II Rough stone 202m 119m 6m

III Rough stone 192m 98m 6m

IV Rough stone 182m 77m 6m

V Rough stone 171m 57m 6m

VI Rough stone 157m 37m 6m

VII Rough stone 141m 17m 6m

Total 38m

However, mining with 6m bench height and slope of bench not exceeding 60° from

horizontal during extraction of blocks will be maintained for safety and scientific point

of view. The quantum of production from the mined-out area is estimated as 191632m3

up to a depth of 38m from the surface level. Out of which, the generated waste and

rejects is estimated to be 9582 m3.

3.2. Mining

Open cast, semi-mechanized mining will be adopted to extract rough stones of

required size from the area for which lease applied for. Before opening a mine, several

aspects should be considered like construction of semi-permanent structures, planning



for the development / production works, formation of faces, laying of approach road to

various benches for movement of dumpers, recruitment of man power, deployment of

machinery, selection of dump sites, stacking yards etc. Top soil\overburden, weathered

materials shall be removed prior to development of working benches.

Hydraulic excavators and tippers in combination will be utilized to recover the

sizeable rough lumps and deliver to the crushing plant to get the required size of 75mm

jelly to 10mm chips.

3.3.Year-wise development/production for the five years

The development involves only removal of small amount of rejects amounts to

5%. The five years production is designed up to a depth of 38m. The year-wise

development /production plan is shown in Plate- VI, VIA, VIB, VIC & VID and the

composite Plan of year-wise sections is given in Plate VII.

trial blast is prerequisite to effect a perfect pre-determined fragmentation and fly rock

control. In case of heavy blasting qualified mine manager has to be appointed for proper

calculation of powder factor and control blasting sequencing and arrangement of

explosives etc.



3.4.3. Blasting

The massive formation shall be broken into pieces of portable size by jack

hammer drilling and shot hole blasting. Powder factor of explosives for breaking such

hard rock shall be in the order of 6-7 tones per Kg of explosives. Blasting parameter

proposed to be adopted for shot holes shall be,

Depth (m) * Burden (m) *Spacing (m) = Volume (M3)

1.00 x 0.60 x 0.75 = 0.45 M3

Quantity of broken rock per hole = 0.45 x 2.6 = 1.17 MT

Blasting efficiency @90% = 1.17 x 90% = 1.05 MT/hole

Charge per hole = 140 gm of 25 mm dia. cartridge.

Quantity of rock broken per day = 69.17m3 or 173M.T.

Requirement of explosives per day = 25 Kg

Impact of mining on environment will be Dust generation, Temporary storage and

utilization of top soil, Land degradation, Stabilization and vegetation of dumps, Adverse

effect on water regime, Socio-economic benefits arising out of mining, Noise and

Vibration. Major impacts, mitigation measures and good practices are discussed below.



Chapter-4

Environmental Management plan

4.1. Air Environment

Dust generation during drilling of shot holes, haul road, smoke from vehicles shall be

controlled by following practices:

Dust extractor or wet drilling to be followed to control dust at source of emission

during drilling.

Sharp drill bits will be used for drilling and regrinding will be done periodically to

reduce the dust generation.

Emission level in all machineries and transport vehicles to be tested once in a year

to keep them in control with proper maintenance and service as per TNPCB

Standards

Water sprinklers along the sides of haul road shall be fixed to control fly of dust

while transporting minerals and waste. Provision for automatic water sprinkle

system on permanent road and water spray by tankers on temporary road shall be

made.

Avenue trees along roads and green belt around ML boundary shall be planted as

per the norms of MoEF to control fly of dust, noise etc

Ambient air pollution monitoring will be carried out as per the regulations.

4.2. Water Environment

Depth of Mining is planned as 38m which is above the ground water table (40 m).

Therefore pumping of ground water does not arise in this mine. The turbid rain water

during rainy season is proposed to settle in a pit before discharging in to the natural

stream for settling the suspended particles.Pump having required capacity is installed

to lift accumulated rain water from working pit to the settling tank. The rain water

should be collected by garland drain around the lease boundary/pit and allowed to a

settling tank.

It shall be ensured that quality of drinking water for the worker is hygienic and

good sanitation system shall be made available.

4.3. Land Environment

Significant impact on land occurs due to change in land use pattern, degradation of soil

quality and dumping of waste. The project is site specific due to the availability of

mineral resources. Hence there is no alternative location suggested for mining.

Some of the measures followed to minimize the impacts are as follows:

The mining activities will be restricted within the lease area only.

The waste material will be utilized for the construction of road and also used by the

local people for construction work.



The surface run off from the lease area will be retain within the lease and used for

plantation, dust suppression and block cutting. So there will be no soil erosion from

the lease area and its surrounding due to mining activity.

The dump will have inward slope with catch drains at inward side of the terrace and

the catch drain of the individual terrace will be connected to the garland drain

outside the periphery of the dump. Retaining wall and garland drain will be

constructed around the dumps and the surface runoff water pass through the

garland drain and finally settled in a settling pit before released outside.

Retaining wall and garland drains for the proposed waste dump will be constructed

to arrest wash offs from the dump.

Maintenance/ repair of vehicles and machineries will not be inside the mining area.

However sudden leakage of oil will be properly disposed off.

4.4. Sound and Vibration

Generation of noise during blasting shall be controlled by delay arrangements in

blasting and use of proper quantity of explosives and strength. Diesel powered

machineries, which is major source of noise in open cast mining will be properly

maintained. Attention shall be paid towards rigorous maintenance of the silencer of the

diesel engines. Protective devices shall be provided for use of persons employed in the

vicinity. Wherever the noise level is found in excess of the stipulated limits, necessary

protective devices like ear plugs will be provided to the employees exposed to such

conditions. No activity to test vibration of longitudinal waves and its peak particle

velocity.

4.5. Solid waste management

Generation of rejects and dumping of waste is discussed under chapter 3. The solid

waste shall be dumped systematically with proper repose angle and stabilization as

follows:

Gradation of dump shall be done automatically as coarser materials go to the

bottom and finer at the top and therefore drain of rain water flow freely to the

bottom without endangering the stability of dump

Stabilization of dump with top soil and tree plantation shall make the dump more

stable on long

4.6. Program of Afforestation

Local trees like Casuarinas, Teak, Eucalyptus and other regional trees etc will be

planted along the lease boundary and avenues as well as over Non-active dumps at a

rate of 30 trees per annum with interval 5m in between. The rate of survival expected to

be 80% in this area. Land use and afforestation Plan is given Plate-X. Density of trees

shall be 1000 per Hectares. The program of tree planting is given in table 4.1.

4.7. Restoration and Rehabilitation Plan

No historical monuments or area of special interest or any other sanctuaries found

around 1 km from this area. Village also located about 1km away and no dwellings

around 500m. Therefore rehabilitation of human settlement or protection of historical

places or monuments does not arise.In the event of closure of mine, the mine worker

shall get alternate work or business like agriculture etc. No serious repercussions

envisaged in the event of cessation of mining activity, as they will be provided

employment in other mines belong to the company. An amount of Rs. 1,50,000 is being

allotted Budgetary provisions for Rehabilitation of Area especially Dump Grading.

No immediate abandoned plan, being a shallow operation. S1-type of stone

fencing will be constructed around the open pit mines and watch and ward shall be to

safeguard the mine from access to surface openings

After completion of mining the land will be used as storage of rain water to

percolation that the ground water will be charged to increase ground water level. And

fishy culture will be developed with aesthetic planting around mines like park. Top Soil,

a precious product of mother earth will be made used for this rehabilitation and land

reforming.
