EXECUTIVE SUMMARY
1.1 INTRODUCTION
The mining Scheme is prepared under the Rule 18 (2) (1) of GCDR, 1999 for the
existing mining lease once in five years for systematic and scientific development of
quarries. It is prepared for the next five years period from 2015-16 to 2019-2020 for
effective implementation. The applicant, Tvl. Aruna Granites, Thiru A.Arunachalam
(Managing Partner), residing at, 109-A, Big Street, Thiruvannamalai Town,
Thiruvannamalai is having vast experience and skill on quarrying of granite blocks in
Thiruvannamalai for the last 15 years.
The mining Lease has been granted from the State Government over an extent of
2.21.0 Hectares in promboke land, S.F.No. 61/2 (P), Nadazhagananthal village of
Thiruvannamalai to quarry black colour granite blacks under G.O.No(4D)2, Industries
(MMB1) Dept. dated 27.08.1999 and lease was executed on 21.01.2000 for a period of
20 years till 20.01.2020.
The Black colour granite deposit of this area is commercially called as “Dolerite”.
It is a type of ferro-magnesian dyke rock comprised of mineral constituents such as
Pyroxene (Augite and Hypersthene) and Plagioclase. Granite is dark black in colour with
light greenish back ground. In view of its excellent appearance it find a steady market in
the building Industry for decorative purposes in the form of slabs, tiles, monuments, cut
to size, markers etc and to some extent in Engineering Industries.
Geological reserves of minerals is estimated as 58,617m3and recoverable
reserves is estimated as around 33,134m3of Black colour Granite out of the mineable
reserves by leaving the required statutory safety distance from the lease boundary as
indicated in the letter issued by the District collector, Thiruvannamalai and as per
mining laws in force.
Safety measures under mechanized loading as per the provisions of Reg. 106 (2)
(b) Metalliferous Mines Regulation,1961 and other labour welfare Amenities as per the

3.0 PROJECT DESCRIPTION
3.1 METHOD OF WORKING
Open cast method of mining by mechanized method is adopted to raise the
production in this area using Line drilling, smooth blasting, black lifting using cranes
and waste and rejects removal using Hydraulic excavators and tippers combination. The
Wire saw cutting is proposed below third bench to recover more granite blacks to
increase the rate of recovery. Granite is exposed in the existing pit and the recovery
factor is taken as 10-20% and it may increase further at deeper levels. Black patches,
side burden and granite rejects are the main development work to raise production
from this area.
The economical depth of mining is taken as 33m safely having considered several
field phenomenon. Five granite benches each of 6m height are formed to win the blacks.
As semi-permanent road was designed such that it will not be affected for a long period
on the western side to enter the main pit. A massive sheet of granites is found on the
East-West side which is amenable for wire saw cutting.
Being a mechanized mining, the applicant had developed a long pit over the
granite band covering the entire area. Road is formed to connect all pits for proper
mining. Pit will be widened properly to reach depth to win better quality granites with
high recovery.
Details of Pit design parameters for production and development work for the next five
years are given in Plate VII. Height of benches shall be maintained as 6m with vertical
face for dimensional cutting during the next five years.
3.2 PROPOSED RATE OF PRODUCTION
The development involves only removal of rejects of some fines and waste rocks
to be generated out of production. About 80-90% of total excavation is estimated to be
the rejects\waste to win the saleable minerals. The annual production is proposed as
2113m3 per annum.
AADHI BOOMI MINING AND ENVIRO TECH (P) LTD, SALEM, TN PAGE 24
3.3 EXTENT OF MECHANIZATION:
The following machinery is proposed to be exclusively for the development and
production work at this mine. The machinery is proposed to be purchased or engaged
on hire basis.
3.3.1 DRILLING EQUIPMENTS:
Drilling of small dia holes is carried out using compressor and Jack Hammers
Combination for regular production of sizeable blacks. Large dia drill shall be used to
make hole for connecting the diamond saw wire for cutting a large size blacks for pre-
splitting arrangements. Depth of each small dia is 2.5m for 3m bench height and large
dia holes shall be 6-8m depends on bench height and extent of cutting on advance
direction.
The spacing of small dia holes shall be 30 - 40 cms and burden from the preface
depends upon the size of black. However it is preferred to have <1m burden from the
preface for effective pulling of blacks. In case of burden in excess of 1.5m the spacing
should be adjusted smaller, less than 30 cms.
To achieve a correct blasting geometry certain amount of trial blast is often
prerequisite to effect a perfect pre-determined to release the black from the parent
rock. In case of wire saw cutting joints and fracture have to be studied below connecting
the diamond wire for smooth cutting and to avoid damage of wire. Details of Drilling
equipments are tabulated below

3.3.2 BLASTING
A controlled Blasting technique is adopted to open a pre-determined crack of the
black from the parent body. Shot-hole with 32-40mm dia. which are drilled by line
drilling and Jack hammers at a close spaced interval of 30 cms will be initiated suitably
with any one or more of the following methods,
Pre-splitting
Cushing blasting with low strength and very low dia. Cartridges axial priming
or standard dia. cartridge with intermittent stemming materials.
Water impulsion with Detonating cords of sufficient power, Preferably 10gms
per metre to develop cracks along the line of drilling,
a.) BROAD BLASTING PARAMETER
Dia. of the hole = 32 - 36 mm
Spacing = 30 cms
Depth = 2.5 m
Burden = Min =1m ; Max = 2m
Charge per Hole = D.cord with water or 70 gms of gun powder or slurry.
In watery holes, the detonating fuse is directly used and water act as a cushion to
move the blacks and form a line of crack. In other cases, small vibrations created by low
explosives open the artificial shear plane \ tensional crack formed by a line of drilling.
Sometimes wedges are used to cut the major blacks into smaller sizes after drilling of
holes to a depth of 30-40 cms. Then the blacks are dressed to desire sizes.
AADHI BOOMI MINING AND ENVIRO TECH (P) LTD, SALEM, TN PAGE 26
A) TYPES OF EXPLOSIVES
Common explosives used to develop a line of crack along the line of drilling are,
Detonating Fuse or Cord with 5-10gms of Expl. per metre,
Low explosives like Gun powder or 70 gms of slurry cartridges,
Ordinary Detonator, class- 6
Safety fuse, class -6.
b) STORAGE OF EXPLOSIVES
The applicant is directly purchasing explosives from the authorized dealer and
they are blasting with help of blaster certificate holders as there is no space for storing
explosives in nearby area. It is advised to store the explosives as per the Indian
Explosives Act, 1958. The explosives to be used in mines being a small quantity the
District collector may be approached to keep the stocks not exceeding 5 kgs at time or
any other quantity permitted by the concerned authorities in a portable magazine of S &
B types.
C) POWDER FACTOR
The Powder factor for waste rock development shall be 2m3 or 7 tonnes per Kg.
of explosives.
3.3.3 LOADING
Loading of waste and granite rejects shall be done by Hydraulic Excavators into
10 tonners tippers for clearing of waste and rejects from the working place periodically.
The applicant is engaging one Hydraulic excavator with 1.7m3 capacity and one tippers
of 10 tonnes capacity for internal transport of rejects from the working face to the
dumps.

3.6 OTHER EXPLORATORY DETAILS
Almost the entire granite Band length on the southern side is opened for winning
the deposit and therefore no further trenching and pitting are required for this area
except two bore hole to prove the depth continuity, colour, texture and recovery factor.
The length and width of the deposit is well established in the working pit but the depth
should be proved by drilling for proper planning of the mines. The proposed core
drilling shall be vertical and 30M depth with Nx and Bx standard size, should be drilled
at the centre along Section XY and AB to probe the depth and quality of the deposit at
deeper levels. Bore hole drilling have to be carried out with in a period of five years.

4.0 SITE ANALYSIS
4.1PHYSIOGRAPHY
The lease area is almost flat terrain to a height of 157m above MSL and quarry
has to be reached a depth of 4-9m above MSL. No major Pond or seasonal track is found
nearby except water log in the old mined out areas.
Water table is located at a depth of 36m from the surface with poor yield. Being a
hard formation yield of water in the pit is very poor. Area around quarry lease is dry
agricultural lands with acacia bushes, dry crops. Trees on regional ground includes
palmera, neem, Palai, Nona etc. Temperature of the region is reported to be 30ºC to a
max. of 40º C during summer. Rain fall of this area is about 1000 mm during monsoons
in a year. Regional crops are sugarcane, ground nuts, Mango, Paddy and maize. There
are no monuments or area of public interest found in the vicinity.

4.2 REGIONAL GEOLOGY:
AADHI BOOMI MINING AND ENVIRO TECH (P) LTD, SALEM, TN PAGE 34
Thiruvannamalai District is comprised of Archaean peninsular gneisses such as
Charnockites, Hornblende gneisses, Biotite gneisses and migmatites etc. They are
intruded by younger formations like dolerite dyke and pegmatite. The dolerite is
running for several kilometers from East to West direction with steep dipping from 80°-
90° with width of 80m. Huge boulder at surface with >3-5m size is good indication of
massive formation at depth. The dolerite dyke is invaded into charnokite/gneissic rock.
The order of superposition of geological sequence are given as under,
Description Geological Age
Top soil – Red soil (2m Thick) - Recent Age
Dolerite ( Black Granite) - Achaean “
Charnockite - Achaean Age
Biotite gneisses - Achaean “
The regional rocks mostly composed of charnockite and gneisses.
4.3 GEOLOGY OF THE PRECISE AREA
Dolerite is commercially called as Black granite by the quarry operators and
buyers. It is a type of ferro-magnesian dyke rock comprised of mineral constituents such
as Pyroxene (Augite and Hypersthene) and Plagioclase. Granite is dark black in colour
with light greenish back ground. The texture is a typical ophitic with fine grained
plagioclase embedded over pyroxene matrix but not visible to naked eye. The rock is
fine to medium grained melanocratic and without any segregation or textural defects,
but more bouldary due to spheroidal weathering.
Based on the field observation, it is presumed the massive sheets of granite are
available at a depth of 9m with estimated rate of recovery of 10-20%. Gang saw size
sheets may be persisted below 9m depth. Two core drilling is suggested as the deposit
is fully exposed at surface with intermittent outcrops with spheroidal boulders.
Dimensional cutting and polishing of these types of hard, compact and massive rocks
exhibits an attractive black colour and attain high polishing. Hardness ranging from 6.5 -
7.5 (Moh’s scale) specific gravity 3- 3.30 gms/cc and attain high polishing which create
an excellent aesthetic value.
AADHI BOOMI MINING AND ENVIRO TECH (P) LTD, SALEM, TN PAGE 35
The area applied for quarry lease contain dolerite dyke intruded into the country
rock comprising biotite gneiss and charnockite. The dyke is partly covered by red
morum soil. The length and width of sheet rock in the lease hold area is measured as
about 240m X 90m and dips vertically. The top soil is 1-2m thick with boulders of black
granite. The mineral constituents of the rock mass are Hypersthene \Augite 50%,
plagioclase 45% and others 5% as identified magascopically.
The orders of geological sequence are,
Description Geological Age
Top soil - Morum (1m thick) - Recent
Dolerite - Archaean formation
Granitic Gneiss\Charnockite - Archaean “
Granitic Gneiss is the oldest rock into which the younger dolerite dykes intruded
later. The strike direction is measured as East to west direction and dips vertical.

4.4 CLIMATIC CONDITIONS
The district receives the rain under the influence of both southwest and
northeast monsoons. The northeast monsoon chiefly contributes to the rainfall in the
district. Most of the precipitation occurs in the form of cyclonic storms caused due to
the depressions in Bay of Bengal. The southwest monsoon rainfall is highly erratic and
summer rains are negligible. Rainfall data from seven stations over the period 1901-
2000 were utilized for analysis and a perusal of the data shows that the normal annual
rainfall over the district varies from 103-458 mm. Average rain fall is reported as
1047mm per annum.
The district enjoys a subtropical climate. The period from April to June is
generally hot and dry. The weather is pleasant during the period from November to
January. Usually mornings are more humid than afternoons. The relative humidity is on
an average between 65 and 85% in the mornings. Humidity in the afternoon is generally
between 40 and 70%.The annual mean minimum and maximum temperatures are
23.78 and 33.95° C respectively. The daytime heat is oppressive and the temperature is
as high as 40.2°C. The lowest temperature recorded is of the order of 19.3° C.

amendments and circulars of DGMS under the provisions of occupational
diseases.
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.
5.2 WATER ENVIRONMENT
No water bodies found nearby the mine area. The ground water table in this area
is reported as 36m depth as evidenced from nearby tube wells. The mining operation in
the proposed area is likely to be above the ground water table and thus the question of
inundation of surface waters shall not arise. Due to this, the ground water may not be
affected or polluted during the course of mining.
There is no major river, drainage and water bodies are found around 1km radius.
Ground water table is located at a depth of 36m and fluctuating between 34-36m in a
AADHI BOOMI MINING AND ENVIRO TECH (P) LTD, SALEM, TN PAGE 49
year where as mining is planned up to a depth of 33m only. Therefore pumping of
ground water or surface 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. No other EMP
required for water quality management.
5.3 NOISE AND VIBRATION
Generation of noise during blasting shall be controlled by delay arrangements in
blasting and use of proper quantity of explosives and strength. 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 (60db), necessary protective devices like ear
plugs will be provided to the employees exposed to such conditions.
5.3.1 VIBRATION
No deep hole blasting at present. In case of deep hole blasting or any large dia
explosive usages. Vibration and air blast noise have to be tested.
5.4 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. The top soil should be dumped along the Lease boundary for dump
afforestation purposes. Top soil should not be mixed with other waste or reject
materials. It should be conserved by judicious utilization in the mine premises.
5.5 WASTE MANAGEMENT
The waste to be generated shall be debris of portable size hard rock with some
fines. No clayey matter shall present in the waste. The solid waste shall be dumped
systematically with proper repose angle and stabilization as given below,
AADHI BOOMI MINING AND ENVIRO TECH (P) LTD, SALEM, TN PAGE 50
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,
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,
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,
Dump should be terraced for every 5m height and stabilized as above,
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,
Description End of 5th Year End of Life of Mine
Topsoil No much of topsoil shall be
removed
No much of topsoil shall be
removed
Reject 46193m3 140290m3
Waste 4869m3 15282m3
All waste and reject materials are dumped eastern side of lease area.
AADHI BOOMI MINING AND ENVIRO TECH (P) LTD, SALEM, TN PAGE 51
5.6 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.
5.7 STABILIZATION 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,
5.8 SOCIO-ECONOMIC BENEFITS ARISING OUT OF MINING
The mine 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 surrounding area. The mining operation will not
disturb/ relocate any village or need resettlement. Thus no adverse impact is
anticipated. The impact of mining activity in the area is positive on the socio-economic
environment of the region. Nadazhaga nanthal village in Black Granite mine is providing
employment to local population and it will be give preference to the local people
whenever there is requirement of man power.
5.8.1 GENERAL
The coming of the project will bring overall improvement in the locality,
neighborhood and the state by bringing industry, roads, water supply, electricity,
employment, living standard and economic growth.
AADHI BOOMI MINING AND ENVIRO TECH (P) LTD, SALEM, TN PAGE 52
5.8.2 EMPLOYMENT
The socio-economic conditions of the surrounding villages are poor as there is no
significant source of earning. The occupational activities are agriculture, cattle rearing
and employment in mines but on daily wages. The mining activity will provide
employment to local people which will increase socio economic status of the area
5.8.3 IMPROVEMENTS IN PHYSICAL AND SOCIAL INFRASTRUCTURE
The opening of the proposed project will enhance the socio-economic activities in the
adjoining areas. This will result in following benefits:-
Improvements in physical infrastructure.
Improvements in Social Infrastructure.
Increase in Employment Potential
Contribution to the Exchequer.
Prevention of illegal mining.
During and Post-mining enhancement of green cover.
5.9 PROGRAMME OF AFFORESTATION
Regional trees like Teak, Mango, Tamarind 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 20 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.

6.10 WELFARE MEASURES
6.10.1Amenities - Nadazhagananthal Village
a. Educational facilities
All the villages in the study area are provided with minimum educational facility.
There are one primary or elementary school at Nadazhagananthal village in the study
area. However, there is no senior secondary school, Industrial/Training school and
college in the study area. For higher education people have to rush to other towns.
b. Health Facilities
The Primary health care centre is located in Nadazhagananthal village distance
between 5 km. Study area of the proposed Multi mineral Granite project is very lacking
in medical facilities in this area. There is no hospital any type. The field investigation has
revealed that during emergency one rush to district hospital at Thiruvannamalai. Deep
probe made during the field survey has revealed that the health institutions located in
AADHI BOOMI MINING AND ENVIRO TECH (P) LTD, SALEM, TN PAGE 57
the study area are not fully equipped due to paucity of man power, medicines,
equipment and ambulances.
c. Drinking water
Drinking water is available in all the villages of the study area. The various
sources of drinking water are taps, wells, tanks, hand pumps and rivers.
d. Electricity
All the villages in the study area are provided with electricity and the same is
available for domestic use, agricultural use and industrial use.
e. Roads
Paved roads are available in eight villages. Where paved roads are not there mud
roads are there. They are connected by mud roads only. In the mining lease area there is
a paved road.
f. Other Facilities
Other facilities available in the study area are Post offices available in
Nadazhagananthal 3km from the mining area. Further, fire station is near
Thiruvannamalai and police station is nearest mining area and nearest railway station
taluk of Thiruvannamalai. Bus services are available in 11 above villages.
It is suggested that the project authority may take up the following community
development activities in order to uplift the socio-economic conditions of the people in
the impact area:
Construction of paved roads where mud roads are still in existence.
Setting up of an occupational training center at village Thiruvannamalai.
Setting up of secondary schools in those villages where it is still missing.
4) Setting of dispensaries or mobile medical units for providing medical aid to
villagers.
Protected water supply in villages where drinking water supply is inadequate.
Village development by adopting selected villages.

Conclusions
With the setting up of the proposed mining project the occupational pattern of
the people in the study area will change to making more people engaged in mining and
business activities. This will reduce occupational dependence of people on agriculture.
In this study area are the facilities like education up to 10+2 level, health, housing,
drinking water, road etc. are far from satisfactory. It is expected that same will improve
to a great extent due to intervention of the project proponent.
