PART – A

3.0 GEOLOGY AND EXPLORATION

a) Physiography:

The area applied for mining lease is gently sloping ground due west. The

outcrops of multi colour granite are well exposed on the western side in the

existing pit and weathered partly on the eastern side and intermittent top soil

capping. The area is surrounded by partly agricultural fields with maize, ground

nuts etc. The surface features of the land are shown in the surface plan in Plate V.

Water table is located at a depth of 45m from the surface in the neighbour tube

well. Temperature of the region is reported to be 28ºC to a max. of 40ºC during

summer. Rain fall of this area is about 900 mm during monsoons in a year.

Regional crops are maize, ground nuts etc. No other area of public interest is

found in the vicinity. Nearest Rail head is located about 25 kms from the site in

Kelamangalam. Post office is available at Padiganalam and Police station at

Denkanikottai.

b) REGIONAL GEOLOGY

The area forms part of the peninsular gneiss, the most wide spread group of rocks

in many parts of the southern India. They consist of a very heterogeneous

mixture of different types of granites intrusive into the schistose rock after the

latter were folded, crumpled and metamorphosed. They include granite

granodiorites, gneissic granites and banded or composite gneisses. The banded

gneiss consists of white bands of quartz-Feldapar alternating with dark bands

containing hornblend, biotite and minor accessories. The peninsular gneissic varity

rose in colour with less grey colour with interclatiopns of quartz-feldspathic

material along gneissosity. Migmatisation of varing kinds of rocks such as basic

granulates; Charnockite and sillimanite gneiss has given rise to grey biotite

gneiss. Subsequent invarsion of rose pegmatite into biotite gneiss has rendered

the grey gneiss to few vestiges within migmatite complex. The rose feldspar

pegmatite permeation is mostly parallel to the gneissosity along with the garnet,

thereby giving a design to the rock. The rose feldspar dominate over grey feldspar

26

giving yellowish white appearance to the rock type. The granite gneiss occurs as

monad nocks and hillocks.

The order of superposition of geological sequence are given as under,

Description AGE

Top soil – Morum(1m Thick) - Recent Age

Pegmatite and Quartz Veins - Archaean Age

Red Multi\Grey Granite - “ (Kolar Group)

Biotite gneiss - Archaean Complex

The regional rocks mostly composed of quartz, plagioclase feldspar,

orthoclase feldspar and accessories minerals like mica.

C) GEOLOGY OF THE PRECISE AREA

The area of mining lease comprised of Migmatite, a type of Red Multi

granite with light colour and good wave patterns. Massive outcrop is found on the

western sides (Red Multi). The eastern side of the area is covered by red soil

concealing the outcrops. Granite on eastern side is appeared to be more

weathered than the western side. The rate of recovery will be more on western

side than eastern side. Average rate of recovery is taken as 20% based on filed

geological and structural aspects.

The mineral constituents are biotite, quartz, orthoclase feldspar and plagioclase

feldspar. The biotite is fine grained and other minerals are medium grained. The

graphic texture and intergrowth of quartz and feldspar indicates that younger

intrusive were invaded into the pre-existing country rock, which preferably would

have been a biotite gneisses(Peninsular Gneisses).Flowage structure and texture

of rock indicates deep seated metamorphism at high temperature and pressure.

Dimensional cutting and polishing of these type of hard and compact rocks

exhibits an attractive pinkish and grey shades of background with attractive wave

patterns. It is a part of peninsular gneisses migmatised by younger intrusive. It is

commercially called as “Red Multi” by the buyers in view of its wave pattern of

accessory minerals.

The rock is hard, compact and sheet in nature so as to cut required sizes of

blocks. The mineral constituents of the rock mass shall be about orthoclase

27

feldspar 40%, quartz roughly 25%, Plagioclase feldspar 25%, mica 15% and

others 5%.

The order of superposition of geological sequence are given as under,

Description AGE

Top soil – Morum(1m Thick) - Recent Age

Migmatite (Red Multi) - Archaean age

Biotite gneiss - Archaean Complex

The strike of the granite body is trending in NE-SW direction and dips

vertically. The regional trend is shown in the geological plan. There is some

gneissic rock formation between two granite bands.

d) DRIANAGE PATTERN:

There are no odai or water bodies nearby. The applicant shall protect soil

erosion from his lease area with proper earth bund on leeward side. She has to

form a silting tank and sand filter for rain water passing through quarry area

before discharging Mine water into natural drains

e) EXPLORATION

i) Already carried out :

The RQP and his Survey team along with the applicant had carried out the

survey, to map the geological and surface details of the area. The multicolour

granite is very well exposed at the surface as outcrops with little top soil capping

intermittently. No exploration was carried out to find the massive sheets for

exploitation.

ii) Propose to be carried out :

Three bore holes are proposed in the Geological plan (Plate-III)

preferably with core drill to a depth of 45m each using Nx and Bx size to study the

rate of recovery, colour, texture and wave patterns etc. Necessary mining

geological details can be observed during mining by employing a Qualified

Geologist to identify the texture and structure of geological formations for proper

28

extraction of blocks and orientation working faces to minimize the wastes and to

increase the recovery.

f) METHOD OF ESTIMATION OF RESERVES

The geological and mineable reserves are estimated by cross- sectional

method up to a depth of 12m.The workable granite deposit is expected from 2-12

m and beyond it. Rate of Recovery of saleable blocks as below based on field

conditions,

Bench Height Recovery

Slice or Bench I = 0-2 mts. 0 %

Slice or Bench II –VI = 2- 12mts. 20 %

Realistic factor of rate of recovery shall be obtained after completion of three

proposed bore holes (Nx & Bx size core size) with some close spaced geophysical

surveys using Wenner configuration system (VES) in soil cover area.

g) GEOLOGICAL RESERVES

The geological reserves is estimated for the area allowed for mining by the

Cross-Sectional method is as 28144 M3 up to a depth of 12m including topsoil

thickness of 2m, having considered the depth of mining, recovery, safety barriers

etc. A detail of estimation of geological reserves is given in the table-I

ii) Proposed rate of production when mine is fully developed

The proposed rate of production when mine is fully developed shall be about 1055

cubic meters of saleable granite blocks per annum.

iii) Conceptual Mining Plan (Final Mine Closure Plan):

Conceptual Mining Plan is prepared with an object of long-term systematic

development of bench lay - outs, selection of permanent dump so as to avoid re-

handling, setting roads, to determine ultimate pit limit, depth of mining and

ultimate pit slope, selection of sites for construction of infrastructures etc.,

Ultimate Pit Dimensions : The ultimate pit size is designed based on certain

practical factors such as the economical depth of mining, safety zones,

permissible area etc., The Ultimate pit of the quarry is given as under,

Pit –I :

Bench L (w) W (m) D(m)I 141 48m 1mII 138m 46m 6mIII 136m 42m 6mIV 134m 30m 6mV 128m 18m 6mVI 115m 32m 6m

Average depth of mining is 12m from the surface level. However, during

extraction of blocks each bench will be of 6m height with vertical slope for proper

dimensional cutting. The quantum of excavation is estimated as 136843m3 to a

depth of 12m, of which, the rejects and waste are estimated as

117219m3including topsoil. Part of rejects will be dumped on the lease boundary

and rest by back filling. Details of Ultimate dump dimensions (m) are given as

under,

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

Total Volume of Excavation up to = 117219m3

Ultimate pit Limit with 12m depth bgl-------------------------------------------------------------------------------------------------------------

d) OPEN CAST MINESi) Mode of Working:

Granite blocks of the following standard sizes will be extracted from this

mine by Open cast semi-mechanized method of mining using Shot hole drilling

with a aid of compressor and Jack hammers ,smooth blasting, block lifting using

cranes and waste and rejects removal using Hydraulic excavators and tippers

combination. Diamond wire saw shall be used to cut the blocks from the parent

body. Working plans and sections showing the layout of faces and direction of

mining are given in Plate VI-X.

The economical depth of mining is taken as 12m having considered several

field phenomenon such as limit of lease boundary. Five benches are designed to

exploit the granite blocks by conventional methods. The benches each of 6m

height and width not less than the height are designed to win the blocks.

ii) BENCH DESIGN PARAMETERS:

Top soil shall be removed and stacked separately along Lease boundary as

34

Earth Bund which will be used for afforestation purposes in phases. Granite

benches will be formed to a height of 6m and width not less than 10m for

movement of machineries while working and the final slope shall be 60°. Initially

the granite benches will be vertical for dimensional cutting of blocks. The

applicant is proposed to produce dimensional blocks to measure,

Minimum size = 1.50 x 1.00 x 1.00m = 1.50 cu.m.

Maximum size = 3.40 x 1.90 x 1.80m = 11.62 cu.m.

Construction of parapet as a fencing around such ultimate pit limit on top of

opencast workings will be arranged to safeguard the mine from inadvertent entry

and hazards.

Overall pit slope 60°

iii) PRE-SPLITTING:

Preface development is must for extraction of dimensional blocks without cracking

or fissuring of the body during drilling and blasting. To achieve such preface a pre

splitting technique using Jet burners on the advanced direction are resorted to a

distance of 6–10m.So as to isolate the working face from the remaining area.

These practices are followed to minimize the formation of artificial cracks and

tensional fissures that are developed after blasting in the advance direction.

Shot - hole drilling with jack hammers and line drilling with top hammers will

be used at close spaced intervals to develop cracks along the line of drilling and to

open the blocks. Low strength explosives or merely detonating fuse may be used

35

to create a “pre-determined line of cracks“ so as to pull out the blocks from

the working faces.

Block - Lifting is an art to remove the cracked rough block from the face by

a Crane/Excavator. The debris and rejects and waste will be cleared from the face

by Hydraulic Excavator and tipper combinations. The rough blocks will further

subjected to dressing to a desired size by secondary cut at the surface.

The rough dimensional blocks will be supplied to the potential domestic and

overseas customers. The waste will be dumped on the specified place remarked

for dumping as shown in the Plate VI-X.

e) EXTENT OF MECHANISATION

The machineries proposed to engage in the mines for systematic operation

and development of quarry to augment extraction of blocks are in Table-IV.

1. Drilling :

Drilling of shot-holes will be carried out using compressor and Jack

Hammers combination. Depth of holes shall be 2.5m for 3m bench height. The

spacing shall be 30 - 40cms and burden from the preface depends upon the size

of block. However the it is preferred to have 1 - 1.5m burden from the preface for

effective pulling of blocks. In case of burden in excess of 1.5m the spacing should

be adjusted smaller, less than 30cms.To achieve a correct blasting geometry

certain amount of trial blast is pre-requisite to effect a perfect pre-determined

crack to release the block from the parent rock.

xi) Public Building Places of worship and Monuments:


temples, archeology, Sanctuaries etc., are found in the radius of 1km.

Karandapalli Village is situated about 6kms on the northern side.

B) ENVIRONMENT MANAGEMENT PLAN

i) Dust: Dust expected to be generated from drilling, hauling roads, place of

excavation etc will be suppressed by periodical wetting of land by spraying using

MgCl2 solutions. Wet drilling and dust extractor arrangements will be provided to

drilling units so as to control raise of dust from the site of drilling. Operators, those

exposed directly to such conditions will be provide such protective equipments like

mask, ear plug, helmet, gloze etc as per the Mines Act.

ii) Temporary storage and Utilization of Top Soil:

Small quantity of top soil shall be dumped separately for afforestation purposes.

iii) Proposal for reclamation land affected by mining activities during and at the

end mining lease period:

The depth of granite deposit is not known. However for economical planning,

the depth is taken as 12m from the surface. Immediate reclamation of land does

not rise for this deposit. However it pit will be used for miscellaneous purposes

like fish pond, rain water storage etc., after completion of mining. All waste and

reject materials will be dumped as per the mining plan.

51

iv) Programme of Afforestation:

Regional trees like Casuarinas. Eucalyptus, Teak, acacia etc will be planted

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

rate of 60 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.

v) Stabilisation and Vegetation of Dumps:

The materials to be dumped shall be very hard in nature and it does not require

any grading separately. The materials like granite rejects shall be graded

automatically during dumping by Excavator and tipper combinations. Part of top

soil will be spread over the Non-active dumps along the slope and edges to plant

tree sapling to form vegetal cover over the dumps. Such vegetal cover will

prevent erosion of dumps during rainy seasons. The program of tree planting is

given as under,

Year Place Type of Trees Number Rate of

survival

I Lease Boundary Neem, Tamarind, Eucalyptus

& Other Regional Trees 60 80%

II Lease Boundary Neem, Tamarind, Eucalyptus


III Lease Boundary Neem, Tamarind, Eucalyptus


IV Lease Boundary Neem, Tamarind, Eucalyptus


V Lease Boundary Neem, Tamarind, Eucalyptus


vi)Treatment and Disposal of water from mines:

Measures to Control Erosion / Sedimentation of Water Course:

The water to be pumped from the quarry shall be treated in sump

containing Sand filters before discharging into natural drainage. Granite sheet

extraction will not produce any waste which pollutes the ground water. Drinking

52

water to mine labour will be supplied from public source or bore well to be drilled

by the applicant.

The rain should be collected by garland drainage around the Lease

boundary or pit and to allow settling in a small pit for settling suspended particles

before passing to natural drainage system.

vii) Measures for minimizing adverse affect on water regime:

Sampling of water shall be done at discharge point to check the quality of

water as per TNPCB standards.

viii) Protective measure for ground vibration:

Only shot hole blasting shall be adopted for breaking the boulders and hard

rocks. No deep hole blasting or machineries will be engaged in this mine.

Vibration from blasting or heavy machineries will be absent.

ix) Measures for protection of historical monuments and rehabilitation of human

settlements likely to be distributed due to mining activity:

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

are 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.

x) Others like legal factors like tribal issues, national park etc

There is no much heavy industries in this area. About 40 persons is

expected to get benefit due creation of employment in this mine. The villager will

get some income due to growth of mining industry. There are no legal issues or

tribal problems associated with this mine. It is patta land in a village and no tribal

issues here. National park, monuments etc totally absent around 5 kms.

(xi) Monitoring schedule: Top soil conservation and dust control, surface water

contamination during rainy season, ground water protection, trees plantation are

the main area of EMP attention is required for this “B” category mine.

xii) Socio-economic benefits arising out of Mining:

The mining operation will create an employment of about 40 persons, of

which 80 % will be from local people (Son of Soil). After development of mine

from this area, not only provide employment opportunities but also the industrial

culture and civilization to the village people. Beneficiary villages are Savirabattam,

12.0 ANY OTHER RELEVENT INFORMATION

The area of mining lease contains Multi colour granite mainly composed of Quartz,

more Plagioclase and less orthoclase feldspar. It is commercially called as Red

Multi, the rock is hard, compact and sheet in nature so as to cut required sizes of

blocks. The geological reserves and mineable reserves are estimated as 28144M3

and 19624 M3 respectively for the lease area up to a depth of 12m. Systematic

mining with proper orientation of working faces and blasting techniques will

improve the recovery, by which the mining cost will be so low from the present

status of mining; also the valuable rock will be conserved. Engaging Diamond wire

saw cutting machine will improve the rate of recovery to more than 25%.

Geotechnical studies:

Chance of slope failure in such hard rock mining is normally negligible. Overall pit

shall be maintained at 60° for working pits. The mine is absolutely free from

geotechnical problems and therefore no geotechnical studies on engineering

properties of rocks and rock dynamic studies had been done for this area.

Hydrological studies (Surface and ground water) By geophysical methods:

The ground water fluctuates between 40-45m in a year. During rainy season

they work on top of the benches and during summer they work on bottom of the

benches so as to avoid unnecessary pumping of ground water. No major ground

water or slurry pumping involved which affect the mining and environment. Base

line data study with aid of NABET Accredited consultant and Hydrogeological study

and Geophysical investigation on ground water potential study under progress for

Environment clearance.

iv) Avenue trees along roads and green belt around ML boundary shall be

planted with density of 1500 trees per Hectare as per the norms of MoEF

to control fly of dust, noise etc,

v) In above all, labours engaged in such dust prone areas should be

provided with safety devices like ear muff, mask, goggles etc as per the

MMR,1961 amendments and circulars of DGMS under the provisions of

occupational diseases.

vi) Labours may be permitted officially to undergo medical checkup to test

silicosis and other respiratory check up once in 5 years

And other guidance required under these laws should be strictly adopted.

13.4 Waste Management

The waste to be generated shall be debris of portable size hard rock with

some fines. No clayee matter shall present in the waste. The solid waste shall be

dumped systematically with proper repose angle and stabilization as given below,

61

i) 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,

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

dump more stable on long,

iii) 1m height parapet shall be constructed for dumps more than 6m height

along the toe to prevent and control wash out from dumps entering into

natural system through rain water,

iv) Garland drainage around dump shall prevent under wash of dump by

hydrostatic pressure to be developed by surface water and control wash

outs and collapse,

v) Dump should be terraced for every 5m height and stabilized as above,

vi) As practically as possible the dump should be made as per the plate VIII

on barren grounds so as to avoid re-handling so that the dump shall be

seasoned and stabilized.

Dimensions of Dump at the end of 5th year and at the end of Life of Mine are

given as under,

Waste --------- ------

13.5 Top Soil Management:

Top soil is a precious product of the earth which normally forms from the

rocks by weathering by millions of years of exposures to the atmosphere with aid

of oxygen and water. These top soil causes for development of amino acids and

genesis of plant kingdom. Therefore, the top soil should be removed separately

before developing the face for granite and waste benches. The top soil should be

dumped along the Lease boundary for dump afforestation and use of agricultural

62

purposes. Top soil should not be mixed with other waste or reject materials. It

should be conserved by judicious utilization in the mine premises.

13.6 Tailing Dam Management:

No water shall be used for quarrying or any other processing except

drinking water to be drawn from public sources. Some stagnation of rain water in

the pit shall be used for wire saw cutting and recycled using slurry pumps.

Therefore need for tailing dam does not arise. But tailing control of rain water flow

during rainy season has to be done by decanting the SPM in a pit before passing

the water into natural system.

13.7 Infrastructure:

Approach road is available from the village road up to the applied area.

Basic amenities for workers and field office shed such as First Aid Station,

canteen, Rest Shed, Toilet etc as per Mines Rules, 1955 shall be made available at

the entrance of mine.

13.8 Disposal of Mining Machinery:

No proposal for disposal of machineries during the first five years of mining

plan period.

13.9 Safety and Security:

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.

facilities. Primary Health centre is available in Karandapalli for medical

emergencies, about 6kms away from the mine.

13.11 Care and Maintenance during temporary discontinuance:

Watch and ward are provided permanently in the Mine premises to monitor

the Mine openings to prevent inadvertent entry. Top soil bund is made partly and

Stone fencing is proposed all around lease boundary to safe guard the mine and

the adjacent livings. Temporary discontinuance will be minimum as there is

enough demand for these materials in tiles industries.

14.0 Economic repercussions of closure of mine and manpower

retrenchments14.1 Number of local residents employed in the mine, status of continuation of

family occupation and scope of joining occupation back.

40 Persons get employment. Most of labours are Agriculturist. In case of

closure of mine, they may continue their own agricultural work or in other

neighbor mines. Being a proposed quarry immediate retrenchment may not arise.

14.2 Compensation given or to be given to the employees connecting with

sustenance of himself and their family members.

In case of any closure of mine the compensation under Industrial Dispute

Act will be paid as per law. All workers shall get retrenchment benefits as per

labour laws under enforcement.

14.3 Satellite occupations connected to the mining industry – number of persons

engaged therein – continuance of such business after mine closes.

The quarrying activity shall lead to development of several ancillary units

and business, which are explained below:

i) Other than mine employment, workshops, spare parts, tyres and tubes and

related several self-employment opportunities.

ii) Several shops and service providers shall grow in the public adjacent to

mines,

iii) Schools and city development shall also be possible owing to the fact of

economic growth in the village.

64

14.4 Continued engagement of employees in the rehabilitate status of mining

lease area and any other remnant activities.

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.

14.5 Envisaged repercussions on the expectation of the society around due to

closure of mine.

Persons on Roll at the time of closure will get benefit as per State Govt.

guidelines as applicable at the time of retrenchment

15.0 Time Scheduling for abandonment:

The following works are scheduled before abandoning the mine,

i) Parapet wall of 2m height will be constructed around the pit,

ii) Planting and monitoring of Afforestation programme.
