1.7 REVIEW OF IMPORTANT CHAPTERS OF MINING PLAN
a) Name of the Mine :
The Block colour granite (Dolerite) Quarry of Tvl. Aruna Granites,
Thiru A.Arunachalam, residing at. No. 109-A, Big Street, Thiruvannamalai
Town, Thiruvannamalai – 606 601, Tamil Nadu.
b) Particulars of approval of mining plan under GCDR 1999 indicate
approval letter No & date:
The mining plan for this Lease area was approved by the
Commissioner ate of Geology and Mining, Chennai in letter Rc.No
819/MM5/2003 dated 13.06.2005 and third Scheme of mining plan expired
on 31.03.2015.
c) Date of commencement of mining operation:
As such, the Block colour granite deposit referred to as „Dolerite‟ occurs
in the lease area is being mined since 12.02.2000 in accordance with the
109
provision of plan approved by the commissioner of Geology and Mining,
Chennai-32.
1.8(a) Deficiencies, if any that existed in the approved mining plan
to be taken note of and rectified by incorporating suitable proposal
for implementation in the scheme of mining.
No deficiencies existed against the proposals given in the earlier
mining plan except afforestation program. The recovery percentage was
proposed as 10-20% and the same was achieved. As the quarry reached 4-
9m depth below the weathered layer, the recovery rate is expected as 10-
20% up to a depth of 33m.
1.8(b) A review of compliance position of salient features of the
mining plan on chapter wise basis bringing out marked
deviations, if any and justifications/reasons thereof. Item to be
covered may include exploration, mine development, exploitation,
afforestation program, reclamation and rehabilitation, control of
dust, noise and ground vibration and any other significant feature
including conditions and stipulations imposed, if any, on year-wise
basis:
i) EXPLORATION:
Systematic remapping of commercially viable granite deposit has
been prepared with relevant information like structural features such as
dip, strike, lineation, joint patterns etc. Based on subsurface geology as
exposed in the working pit and marketability, the geological and minable
reserve has been computed to a reasonable depth of 33m bgl. In the earlier
approved mining plan, it has been proposed to lower two bore holes to
ascertain the depth persistence of deposit and recovery of gang saw size
blocks. But the proposed exploration has to be done during the ensuing
years (2016-18).
The proposed two core drilling shall be vertical to a depth of 30m
from the pit bottom with Nx and Bx standard size at the center along X1-Y1
and X2-Y2 sections to probe the depth and quality of the deposit at deeper
levels during the period 2016-17.
110
ii) MINE DEVELOPMENT
The mine development was undertaken as against the proposals laid
down in the five years plan period and the development actually done is
detailed below.

i) REVIEW OF MINE DEVELOPMENT:
During the year 2002-05 the lessee concentrated in development
work and no production during this period. Again during the year 2007 -
2015 the lessee had done only development work.
ii) EXPLOITATION
Dimensions of the Existing working pits are given as under in Table –V.

II I 40m 26m 4m
111
Maximum depth at the bottom bench floor level is 9m from the
surface. Details of Pit dimensions and depth of quarry are shown in the
Surface plan (Plate –V)
iii) WASTE MANAGEMENT
The waste that generated during the approved mining plan period is
reported as 1450 m3 of Granite rejects (Mining losses, cracks and small
boulders of granite) were dumped randomly around the pit. It has been
advised to the applicant to dump all such waste separately as per
GCRD,1999 within the lease hold area with proper grading. Wide spread of
dump causing land degradation should be avoided.
Proper garland drainage and retention wall at the toe of dump should
be formed to control wash outs and drain rain water with minimum
contamination.
The dimension of dumps at the end of 5th year and at the end of life
of mine is demarcated in the mine conceptual plan and sections. (Refer
Plate No.VIII)
vi) AFFORESTATION:
It is proposed to plant 20 trees per annum over the dumps and the
inner boundary of lease during the mining plan period. As against the
proposal, only 15 plants were planted along the approach road in the last
five years of scheme of mining plan period. However, it is proposed to plant
20 trees per annum along the inner boundary of lease during the ensuing
five years period of mining. (Refer plate No.X).
vii) LAND RECLAMATION AND REHABILITATION
It is proposed not to backfill the mine pit(s) and these may be
utilized as storage of rainwater after the mining activities over. The pit
boundaries shall be fenced to safe guard from the inadvertent entry by
proper fencing. However, the waste dump areas will be taken up for
planting suitable trees. The reclamation of the mine–pit(s) is not proposed
in the ensuing five years period of mining.
viii) CONTROL OF DUST, NOISE AND GROUND VIBRATIONS:
The drilling and blasting are being carried out as per the proposals
laid down in the approved mining plan. Shallow holes of 32mm dia. holes
are drilled. Conventional low explosives are being used. The scale of
blasting is however very less considering the rate of production.
112
In view of above, there is no adverse effect on dust, noise and
ground vibration by mining activities. As proposed in the mining plan
approved earlier, the drilling and blasting parameters were followed. The
drilling and blasting parameters will be as designed as above in the
ensuring five years period.
1.9 Review of the compliance position of conditions and stipulations
imposed, if any, while approving the mining plan. In case of non-
compliance/partial compliance detailed justification/reasons thereof may
be furnished along with proposal for compliance in the ensuing period:
The mining plan for area under reference has been approved with
conditions to comply with the provisions of Mines Act, Mines Rules and
Regulations and the rules framed there under. The proposals given in the
earlier mining plan for this area has been complied with the above rules
and regulations. Besides, the lessee has generally carried out the mining
operation in conformity with the above Acts and Rules and adhered to the
general/special conditions stipulated by the State Government for providing
the statutory safety distances to be maintained.
1.10 Review of compliance of violations pointed out after
inspections made under GCDR, 1999 during last five years. The
position emerging out of the yearly review of the mining plan while
checking up implementation of the mining plans in the field shall
also be taken note of at this stage.
As the validity of third scheme of Mining Plan expires on 31.03.2014.
There is no violations letter pointed out by the Department of Geology and
Mining, Thiruvannamalai district and commissioner ate of Geology and
Mining, Chennai.
1.11 Any other points requiring attention in the interest of proper
mine design, development and conservation and environment and
ecology of the area:
The present as well as the proposed mine working is so designed in
such a way mainly keeping in view of conservation of granite deposit,
afforestation, and production of environment and ecology of the mine area.
1.12 SIGNIFICANT FEATURES:
No significant feature observed in this area.

3.0 GEOLOGY AND EXPLORATION
a) Physiography :
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.
b) REGIONAL GEOLOGY
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
115
c) 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 type 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.
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 order 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.

Based on the field condition and lease boundary the economic depth
of mining is taken as 33m and the mine has reached a depth of 9m.
However the Granite band is continuing at depth with better recovery and
quality for mining.
120
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.
Sampling:
In case of core drilling, the lithology, colour, texture, cracks, joints
mineral grains alignment have to be observed and manual polishing and
engineering properties can also studied for decorative purposes.

or over all pit slope shall be 60° and each bench height shall be 6M height
equal to the boom height of excavator and vertical. During working
normally 6m will be maintained as per the scheme of mining. After
completion of mining the pit will be used for fishy culture.
5.0. MINING
5.1 Salient Description of present Mining methods:
Open cast method of mining by mechanized method is adopted to
raise the production in this area using Line drilling, smooth blasting, block
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 blocks 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 blocks. 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. Massive sheets 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.
5.2 a) Year Wise Production and Development for the first five Years:
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 rough
122
blocks. The annual production is proposed as 2113m3 per annum. The
production schedule for the five years is given below in Table-IX and
production planning is shown in Plates VI,VIA & VIB.

Safe benches with proper height were formed and pit will be widened
properly to reach depth to win better quality granites with high recovery.
Details of bench dimensions are given in Plate VI,VIA & VIB.
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.
i) BENCH DESIGN PARAMETERS :
Top soil shall be removed and stacked separately along Lease
boundary as 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 1.00 m = 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.

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 to create a “pre-determined line of
cracks“so as to pull out the blocks from the working faces or wire
diamond wire saw cutting.
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 earmarked for dumping as shown in the Plate VI-X.
124
b) Drilling
Drilling of small dia holes is carried out using compressor and Jack
Hammers Combination for regular production of sizeable blocks. Large dia
drill shall be used to make hole for connecting the diamond saw wire for
cutting a large size blocks 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 block. However it is preferred to have <1m
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 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 block 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

ix) 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.
Summers
The sun is at its glory and shines very brightly during the summers. During
the summer months, i.e. from May to June, the temperature varies
between 27°C and 40° C. Therefore, the climate is quite hot. May is the
hottest month. Cottons are recommended during this time.
Winters
In winters, which starts from December and lasts till February, the
temperature ranges between 20° C and 30° C. The climate remains pleasant
during this time, as the temperature rarely falls below 20° C.
Monsoon
Though the rainfall is very frequent and uniform throughout the year,
just like the flow of pilgrims and tourists, the city receives the major share
of rainfall between the months of July and October. The average rainfall is
85 cm.

x) Human Settlement :
The following villages are found in the buffer zone with population as
per 2011 census. The Nadazhagananthal Population of 2184 peoples of
both male (1140) and female (1044).
xi) Public Building Places of worship and Monuments:
No infrastructures like residential building, places of special interest like
archeological monuments, Sanctuaries etc., are found in the radius of
500m. Nadazhagananthal Village is situated about 1kms on the western
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:
Top soil shall be dumped along separately on the eastern side of
lease area for plantation purposes over inactive dumps after end of year
mining operation.
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 33m from the surface. Immediate
reclamation of land does not rise for this deposit. However it pits will be
used for miscellaneous purposes like fish bond etc., after completion of
mining.

iv 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.
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,
Table-XIII
Year Place Type of Trees Number Rate of
survival
2015-16 Lease Boundary Teak, Mango, Tamarind
& other regional trees. 20 80%
2016-17 Lease Boundary Teak, Mango, Tamarind
& other regional trees. 20 80%
2017-18 Lease Boundary Teak, Mango, Tamarind
& other regional trees. 20 80%
2018-19 Lease Boundary Teak, Mango, Tamarind
& other regional trees. 20 80%
2019-20 Lease Boundary Teak, Mango, Tamarind
& other regional trees. 20 80%
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 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.
142
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 is used in this quarry.
Vibration from blasting or heavy machineries will be negligible. In case of
any report of vibration from the public Vibration test shall be conducted.
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 500m radius from this area. Village also
located about 1kms 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 industry in this area. No other quarry is
operating around 500m radius. 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 Poramboke land in a village and no tribal
issues here. National park, Monuments etc totally absent around 5kms.
(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.

SOCIO-ECONOMIC ENVIRONMENT
Introduction
This section of the EIA report deals with Socio-Economic impact
assessment of the proposed Mining Project promoted by Tvl.Aruna Granites
properator, Thiru.A.Arunachalam, residing at. 109A, Big Street,
Thiruvannamalai town, site located at Nadazhagananthal village, Sub-
district Thiruvannamalai, District Thiruvannamalai, Tamilnadu.
The objects of the socio-economic impact assessment are as follows:
143
a) To study the socio-economic status of the people living in the study area
of the proposed mining project.
b) To assess the impact on socio-economic environment due to proposed
mining project.
Methodology
The methodology adopted for impact assessment is as follows:
The methodology adopted for the study is primarily based on the
review of secondary data, such as Primary Census Statistical
Handbook of Thiruvannamalai District in Thiruvannamalai taluk, 2001
& 2011 for the parameters of demography, occupational structure of
people within the study area of 300m and 500m radius around the
proposed plant. The salient features of the demographic and socio
economic aspects of the study area are described in the different
sections.
The details of the activities and population structure have been
obtained from Census 2001 and 2011 and analyzed.
Based on the above data, impacts due to mining operation on the
community have been assessed and recommendations for further
improvement have been made.
Population Characteristics – Nadazhagananthal Village

469 (56 %) females increased to 596 (57 %) classes as literates in 2011.
Sex composition is the most important demographic characteristics
that affect the incidence of birth and death. The average sex ratio in
Thiruvannamalai district, Nadazhagananthal village was 1037 during 2001
144
and decreased to 915 during the year of 2011. The lowest sex ratio may be
either due to the migrants for educational purpose and employment
opportunities and due to infant birth of female is very Low during the year
of 2011.

Occupational Characteristics - Na–azhagananthal Village
The term workers denote the population engaged in primary,
secondary and tertiary activities classified in the census reports of Indian
government. During the year 2001 Nadazhagananthal village had 977
workers accounting for 59 percent of the total population of the Village.
During 2011 there were about 1042 (47 %) according to the census. There
were about 496 men (61 %) during 2001 which is increase to 655 persons
(57 %) according to census 2011. There were about 481 (57 %) female
145
according to 2001 which is decreased 387 (37 %) female during 2011
marking a decrease of 94 women over the previous census.
In Nadazhagananthal village had a total main workers accounted of
786 (48 %) persons during 2001 census which is increase to 833 (38 %)
persons during 2011. There were about 348 (41 %) women in 2001 and
280 (26%) women according to the census 2011 marking an decreases of
68 women over the previous census.
Study on occupation characteristics of population should analyze the
workforce engaged in different type of occupation. Cultivators are the
major category of occupation representing the workforce owning land.
Nadazhagananthal village had total cultivators 556 (56 % of the total
workers) cultivators. The proportion of cultivators to total workers is
calculated as a percent for the two census years 2001 and 2011 for the
taluk of Thiruvannamalai in Nadazhagananthal village. There were about
316 (63 %) men in 2001 which is decrease 309 (47 %) according to census
2011. Nadazhagananthal village had female cultivators 240 (49 % of the
female workers) cultivators during 2001 census which is decreased 177 (45
%) during according to census 2011.
The distribution of agricultural laborers in the study area for the two
census periods has revealed that the study area has experienced a decline
in the proportion of workers classed as agricultural laborers between 2001
and 2011. Thiruvannamalai taluk in Nadazhagananthal village had
agricultural labourers 151 (15 % of the total workers) agricultural labourers
during census 2001. There were about 70 (14 % of male workers) men in
2001 which is increase to 94 (14 % of male workers) according to census
years 2011. Nadazhagananthal village had female agricultural laborer
decreased 66 (17 % of female workers) census 2011 compare to the
previous census year 2001 about 16 % of female workers.
This group includes the employment of workers in manufacturing
activities. Agro based industries, located in the study area engages a
sizeable amount of workers. The distribution of secondary workers in the
study area is calculated as percent to the total workers. The proportion of
secondary workers to total workers has experienced decreasing trend in the
Nadazhagananthal village area between 2001 and 2011. Secondary
146
workers during 2001 and 2011 it could be stated that this may be due to
the opening of a number of manufacturing units in the study area.
The tertiary workers include the labour force engaged in service
sector such as education, medical, judicial, finance, administration,
recreation, trade and commerce and transport. In Nadazhagananthal village
had tertiary workers accounted for about 5percent of the workers during
2001 census it is increased 17 % according to census 2011. There were
about male tertiary workers of 43 (8 % of the male workers which is
increases 146 (22% of the male workers) according to census 2011. There
were about 13 women tertiary workers (2 % of the female workers) during
2001census which is almost increased to (9% of the female workers)
according to census 2011.
The study area has experienced a change in the occupational structure
in the form of a decline in the proportion of cultivators, agricultural laborers
and an increase in the proportion of tertiary workers.
In Nadazhagananthal village had non workers population accounted of
1142 (52 % of the total population) according to census 2011. Which is
decreased from previous census 2001 had population 659 (40 %). There
were about male non workers of (38 % of the male population) during the
census 2001. Which is increase to 485 (42 % of the male population)
according to census 2011. Because of more number of people are educated
most of people living the village had mining industries money earn our daily
life.
Amenities - Na–azhagananthal Village
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.
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
147
made during the field survey has revealed that the health institutions
located in the study area are not fully equipped due to paucity of man
power, medicines, equipment and ambulances.
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.
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.
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.
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:
1) Construction of paved roads where mud roads are still in existence.
2) Setting up of an occupational training center at village Thiruvannamalai.
3) 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.
5) Protected water supply in villages where drinking water supply is
inadequate.
6) 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.
148
are far from satisfactory. It is expected that same will improve to a great
extent due to intervention of the project proponent.

xiii) Waste management: The waste to be generated shall be debris of
portable size hard rock without any red soil and connate water and
therefore collapse of dumps is not possible for this mine. All waste and
reject materials shall be dumped on the eastern side of the lease area.
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
As a part of Granite conservation and Environmental issues small
pieces of granite shall be used for tile and monument industries. Huge gang
saw size blocks shall be used for making slabs etc as well as for exports.
xiv) Tailing dam management:
No ground water discharge or slurry from the mine and thereby no
tailing or settling tank required for this mine except a small pit for
decanting the slurry water.
12.0 ANY OTHER RELEVENT INFORMATION
Black granite is a commercial name for “Dolerite”. These rocks occur
mostly as dykes cutting across the country rocks. The Dolerite consist
mostly of Plagioclase feldspar embedded over matrix of Ferromagnesian
minerals like Pyroxene (Hypersthene-Augite) with small quantities of
Magnetite (Ilemenite). The geological and mineable reserves are estimated
as 58,617 M3 and 33,134 M3 up to a depth of 33m. 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 45%.
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:
There is no major river, drainage and water bodies are found around
1km radius. The ground water fluctuates between 34-36m 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

The Mined out Land during the mining scheme period is very shallow
and it will be used as percolation Pond for storage of water for Agricultural
use after reaching sufficient depth.
13.2 Water Quality Management:
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 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.
13.3 Air Quality Management
There is no gaseous matter to be generated in this quarry. Dust
generation during drilling of shot holes, haul road, smoke from vehicles
shall be controlled as given below,
i) Dust extractor or wet drilling to be followed to control dust at source of
emission during drilling,
ii) 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,
iii) Water sprinklers along the sides of haul road shall be fixed to control fly
of dust while transporting minerals and waste,
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
154
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 clayey matter shall present in the waste. The solid
waste shall be dumped systematically with proper repose angle and
stabilization as given below,
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,
155
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 4th year and at the end of Life of
Mine are given as under,
Description End of 4th 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.
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. 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.
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 mining
Lease 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 last five years of
Scheme of mining period.
156
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.
13.10 Disaster Management and Risk Assessment:
Name and Address of Contact Person coordinating in case of
Eventuality is,
Name of the applicant : Tvl.Aruna Granites,
Address Thiru.A.Arunachalam,
No.109A, Big Street,

Manager will be appointed and he will be provided suitable
communication facilities. Primary Health centre is available in
Thiruvannamalai for medical emergencies, about 11kms 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. Temporary
discontinuance will be minimum as there is enough demand for this
material in tiles industries.
14.0 Economic repercussions of closure of mine and
manpower retrenchments
14.1 Number of local residents employed in the mine, status of
continuation of family occupation and scope of joining occupation back.
21 Persons get employment. Most of labours are Agriculturist. In
case of closure of mine, they may continue their own workers and there is
no other granite quarry found within 500m radius. Being a proposed quarry
immediate retrenchment may not arise.
157
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.
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,
