(ii) Brief description of nature of the project
The nature of the project is extract the Limestone Mineral and use the minerals for the
processing plant, the method of mining is opencast semi mechanized method and the excavation
is not made by the system of deep hole blasting along with heavy earth moving machinery.
The drilling is carrying out with jack hammer of small diameter (30-32 mm) at shallow
depth is performed and blasted with class 2 slurry explosives. The imitation system is done with
controlled blasting techniques under the supervision of competent personnel’s.
The entire mined out mineral is used for its own captive plant in the name of
M/s. Air Mineral Enterprises which is located in Sirugudi, 3.0kms from mining lease area for
Pulverizing and also sold to the nearby cement and lime based industries which are located
within a radius of 35Km from the mine site.
Production details given below.
Mineral reserves (ROM) = 46,565Ts
Limestone (60% Recovery) = 27,939Ts
Mineral Rejects (40%) = 63,424Ts
Top soil = 3,612Ts
The mineral rejects is 40% of ROM which includes rock fragments, impurities
etc., mineral rejects are generated during the previous plan period was dumped in the western
portion of the area. The mineral reject that would be generated during the present plan period is
proposed to fill old pit situated in the southwestern side of the lease area.
(iii) Need of the project and its importance to the country and or region
Depending on the quality of the deposit, limestone can be quarried to service the needs of
the building and construction industries as raw material. Cement is a key ingredient of concrete,
huge volumes of which are poured each day to serve as roading, foundations, structural beams
and columns.
Agricultural use:
Limestone deposits with a calcium carbonate content around 90% can be mined to be
used by the farming sector. By crushing the limestone, various grades (based on particle size)
can be produced. These products are marketed as ‘agricultural lime’ Soil acidity is one of the
factors that can influence plant growth and can seriously limit crop production.
The calcium carbonate content of the limestone is capable of neutralising some of the
acid in the soil. This also has the effect of freeing up some of the soil minerals, such as
phosphates, and making them available for absorption into the plant.
The southern region accounts for the largest share in overall cement production due to the
vast availability of limestone. Cement industry is one of the main beneficiaries of the
infrastructure boom. Weaker sections housing, construction of public toilets, schools in rural area
apart from several private and public infrastructure projects will also give tremendous boost to
the cement consumption in the state.
Mineral Industries of the state of Tamilnadu provides employment opportunities for the
people of the state as well as in the specific project area. The Mining is one among the major
core sector industries which plays a vital process of country’s economic development and
foreign exchange.
(iv) Demand and supply gap
Limestone is the main raw material for cement production; the demand is always there
with that of cement. The mine produces good grade limestone leading to conservation of mineral
resources. The cement market has growth due to the central government liberalization policies
and new schemes for housing, road projects. The cement demand growth is anticipated to
increase on infrastructure development and the higher demand from the housing sector &
industrial projects.
(v) Imports vs indigenous production
There is no import of Limestone at present in India. India especially the peninsular India
(southern India), the southern India has good resource of Limestone and has a great demand in
the international supermarket. Indigenous Limestone almost shares more than 50% requirement
in the world.
(vi) Export Possibility
India, the world’s second largest cement manufacturer. United Kingdom is the largest
buyer of Indian limestone followed by Ireland and Belgium which imported Indian limestone.
Average price of indian limestone per unit is USD 4.05., currently experts two to three per cent
of its production and that is mainly in the form of clinker, an input for cement making to
neighboring countries.
(vii) Domestic/Export Markets
Sirugudi Limestone mine is one of the captive Limestone mine of the lessee and feeding
Limestone to the nearby cement factories and with the financial back up the mine.
(viii) Employment Generation (Direct and Indirect) due to the project
About 12 employees are deployed for this Limestone Mines directly and indirectly about
10 people will be benefited from the nearby local villages.
The above man power is adequate to meet out the production schedule and the machinery
strength envisaged in the plan and also to comply with the stationary provisions of mine safety
regulation.
It is been ensured that the labors will not be deployed less than 18 years, No Child
labors will engaged or entertained for any kind of mining operations. All the labors engaged
for mining operations will be insured till the end of life of mine.

Limestone with 20m depth. The mining operation is proposed in the patta land hence alternate
site for this project is not considered. The project is site specific.
(iv) Size or magnitude of operation
The total area of the project is about 0.94.5Ha. Out of this only 0.22.4 Ha is proposed for
an optimum depth of maximum 20m from RL 220.0m to RL 200.0m has been taken into
consideration for the utilization of the mineral in the present plan period.
Anticipated Daily production is about 32 tonnes (1 to 2 Tippers per day).
(v) Project description with process details (a schematic diagram/flow chart showing the
project layout, components of the project etc. should be given)
Details regarding topography, Geology of the area, Method of mining, Machineries
required and production details area given below:
Physiographic:
The area is almost plain topography sloping towards southern side, the altitude of the area
is 220m above MSL. It is a dry barren land, only seasonal cultivation is carried out. Water table
is found at a depth of 35m during summer and 30m during rainy season.
Geology of the area:
The area comprises crystalline Archaean rocks of deep seated metamorphic origin which
include mainly calc-gneiss, cordierite-sillimanite Gneiss, Biotite gneiss and granite gneiss. The
gneisses appear to have resulted by migratizations of the pre existing sediments by intrusive of
high grade metamorphism viz. High temperatures and pressures. In addition, younger intrusive
such as granites, pegmatites and quartz veins are found within the limestone. The above said
different types of metamaorphosed rocks occur in the form of long, narrow, parallel bands which
are traceable over a long distance. Limestone, band is noticed with prominent outcrops.
The regional trend of the rock in the area is N600E – S600W with Dip 60o NW. The
area was surveyed in detail to prepare a Geological map in the scale of 1:1000 showing the
various formations and attitude of the deposit. It is inferred that the Limestone mineral is of
cement grade and in form Band running N600E – S600W with dipping 75o NW. Reddish soil
cover upto a depth in about 1.0m. Recovery of minerals is estimated as 60% of the total
excavation of the ore body. The recovery percentage is based on the knowledge gained from the
present mine workings and adjacent working mine in this region, by the field tests carried out in
the lease area and analysis done in NABL Laboratories.
The general geological sequence of the limestone deposits is as follows:
Order of Super position:
AGE ROCKFORMATION
Recent - Reddish Soil
Achaean - Crystalline Limestone
- Calc-gneiss.
The physical attitude of the limestone band is demarked as follows:
Strike length (m) : 87
Width (m) : 55
Depth (m) Proved : 20
Strike direction : N600E – S60
0W
Dip amount and direction : 75o
NW.
The deposit is covered by 1.0m thickness of topsoil followed by 19m thickness of Limestone
bed.
Method of Mining:
The method of mining is opencast semi mechanized method, in the Mining operation
deep hole drilling and blasting is not carrying out. No Heavy Earth moving Machinaries like
excavators are deployed in this mining operation.
The limestone will be separated manually and loaded directly into the tippers. The
blasting is being carried out occasionally. The drilling is carrying out with jack hammer of small
diameter (30-32 mm) at shallow depth is performed and blasted with class 2 slurry explosives.
The imitation system is done with controlled blasting techniques under the supervision of
competent personnel’s.
Open Cast Working:

Limestone Mine
BASE LINE STUDIES
The base line a study is prepared for Sirugudi Limestone Mine. Base line studies provide
a base data for regular Environmental Monitoring and Environmental Impact Assessment (EIA).
The international Association for Impact Assessment (IAIA) defines the base line studies
as the process of identifying, predicting, evaluating and mitigating the Bio physical, Social and
other relevant effect of development proposals prior to major decision has been taken and
commitment mode.
Hence the baseline study provides a bench mark for carrying out environmental Impact
assessment due to the course of quarrying and mining activities. The purpose of these studies is
to evaluate the benefited and adverse effect of developing activities on the neighborhood
environment and the area where the mining is proposed to carry out.
M/s. Sivam Mines has applied for Limestone Mine lease for over an extent of 0.92.5 Ha in
S.F.Nos. 630/1A, 1B, 631/10, 11, 630/2 in Sirugudi Village, Natham Taluk, Dindigal District,
Tamilnadu State
The area proposed for mining for the present Scheme period is about 0.54.6 Ha which is
below 25% of the total area applied for lease; hence the impact assessment due to mining may be
considerably low.
As per the Gazette notification 2006 the proposed project falls under B2 Category.
The area proposed for mining is a fresh area and there are no factories, industries within
the radius of 1Km hence the atmospheric air is quite fresh. The area exhibits flat terrain which is
devoid of vegetation and Agriculture. In some small patches small agricultural activities are been
carried out by drift irrigation some thorny bushes and wild gars are found in the area with scanty
Palm trees (Borassus falabellifer). Tridax procumbens and Lucus aspera are some of the
common species along with Julia flora trees. The density of these about 20% to 40% in the area
and the remaining area is dry barren land.
As no agricultural activities are carried out the people in and around the villages migrate
to nearby town for their livelihood. Most of the people are illiterate and depend upon the
Garment factories, mining is the main industry in this district.
The project in this area will fetch a quit considerable employment to nearby village which
in turn enhance the earning source of the nearby villages. The comprehensive base line studies
and standards constitute of collecting data on Ambient Air quality, Dust fall rate, Water quality,
Soil analyze, Noise level and Ground vibration study in the area proposed for mining along with
Flora and Fauna statistics.
The Methodology adopted in this project is based on the basic principles of capitalization
identification analysis and preparation of action plan to Mitigate negate or adverse impact.
Baseline studies adverse the significant environmental Issue and also provide necessary
information pertaining to the Environmental Attributes in the project area. Monitoring and
evaluating the effect of the works environment factors on health of people working on Limestone
mine.
Collection and analysis of Baseline Environmental Data.
Baseline Environmental Data plays a key role in the EIA procedure as it provides the
important information on the Environmental parameters which are likes to be affected due to the
Limestone mining activities.
Physiography
The area is almost flat terrain. The general drainage pattern of the area is of sub-dendritic
and dentritic pattern. Only seasonal cultivation is done. In some areas agriculture is done with lift
irrigation. The main crops are groundnut, paddy etc. There is no thick vegetation. Water table is
found at a depth of 35m during summer and 30m during rainy season. The area exhibits a
tropical climate and the temperature goes upto 400C in summer and falls down to 250C in
December – January. The wind direction is NE-SW and vice-versa. Average annual rainfall is
about 850 mm in northeast monsoon season.
Geology of the area
The area comprises crystalline Archaean rocks of deep seated metamorphic origin which
include mainly calc-gneiss, cordierite-sillimanite Gneiss, Biotite gneiss and granite gneiss. The
gneisses appear to have resulted by migratizations of the pre existing sediments by intrusive of high
grade metamorphism viz. High temperatures and pressures. In addition, younger intrusive such as
granites, pegmatites and quartz veins are found within the limestone. The above said different types
of metamaorphosed rocks occur in the form of long, narrow, parallel bands which are traceable over
a long distance. Limestone, band is noticed with prominent outcrops.
The regional trend of the rock in the area is N600E – S600W with Dip 60o NW.
The area was surveyed in detail to prepare a Geological map in the scale of 1:1000 showing the
various formations and attitude of the deposit. It is inferred that the Limestone mineral is of cement
grade and in form Band running N600E – S600W with dipping 75o NW. Reddish soil cover upto a
depth in about 1.0m. Recovery of minerals is estimated as 60% of the total excavation of the ore
body. The recovery percentage is based on the knowledge gained from the present mine workings
and adjacent working mine in this region, by the field tests carried out in the lease area and analysis
done in NABL Laboratories.
The general geological sequence of the limestone deposits is as follows:
Order of Super position:
AGE ROCKFORMATION
Recent - Reddish Soil
Achaean - Crystalline Limestone
- Calc-gneiss.
The physical attitude of the limestone band is demarked as follows:
Strike length (m) : 87
Width (m) : 55
Depth (m) Proved : 20
Strike direction : N600E – S600W
Dip amount and direction : 75o NW.
The deposit is covered by 1.0m thickness of topsoil followed by 19m thickness of Limestone
bed.
Vegetation
The area is almost flat terrain. The general drainage pattern of the area is of dentritic
pattern. Only seasonal cultivation is done. In some area agriculture is done with lift irrigation. The
main crops are groundnut, chilli, cereals etc., some thorny bushes are grown, there is no thick
vegetation.
General approach to Environment
The Environmental besides data comprise of the features present of the site area its
includes environmental features such as forest area, conservation area, water bodies, industries,
wild life and fauna place of historic and importance etc.,
The data collected to cover the following.
1. Air environment 2. Noise Environment 3. Water environment 4. Ecology (Biological and Cultural Environment) 5. Physical Environment
Air Environment
Air environment is responsible for the health of human beings, animals, wild life and
vegetation. Air pollutants emitted by project and non point source are transported dispersed or
concentrated by meteorological and topographical conditions.
The atmosphere is dynamic system which absolute range of solid, Liquid or gases from
both Natural and Manmade source. There substances travel through the air disappear and reveal
among themselves and also with other substances both physically and chemically which result in
air pollution.
The limestone propose to mine is non toxic which does not emit any undesirable
pollutants in the form of solid liquid or gas. The dust emitted during the transportation of
vehicles the drilling will be carried out in wet condition to prevent dust into air and the haul
roads will be periodically sprinkled with mist water spray to prevent dust into the atmosphere.
The area in and around is quit fresh and the impact an air environment will always be under
controlled and will be monitored. No processing or beneficiation is proposed except mining
hence the impact an air will be controlled monitored and mitigated.
The ambient air quality within the study area on both core and buffer zone forms the
baseline information. The air quality monitoring points selected based on the Meteorological
conditions, topography of the study area and likely impact boundary location of the ambient air
quality monitoring stations was selected on the basis of wind pattern.
The ambient Air quality monitoring stations are shown in the map. Four major pollutions
were consideration significantly.
I. Particle matter - PM II. Suspended Particle Matter - SPM
III. Sulphur dioxide - SO2 IV. Nitrogen dioxide - NO2
Respectively the overall of emission we identified the direction of the wind in the
majority observed time was predominantly south west to North East direction. The Air quality

Noise Environment
Sound/Noise can be defined as atmospheric or airborne vibration perceptible to the ear.
Noise is usually unwanted or undesired sound. Sound loud enough to be harmful is called noise
without regard to its other characteristics hence noise has a significant impact on the quality of
life and in that sense it is a health problem in accordance with the (WHO) definition of health.
Impact of noise on environment depends on various factors such as intensity distance
from the source type of exposure and nature (Impulse or continuous), the type of activities
movement of machineries, traffic density etc., hence it is to measure the levels so as to adjust the
environment Impact and undertake amendment measures if warranted.
Standard precession noise level meter were used for the purpose. The readings in the
form of instantaneous sound measures levels were taken in the time brackets of two hours in
order to here carry out assessment of noise level in the area.
There are no heavy industries nearby; the noise level of the area will be as same as the
regional level. More over the noise level measurements does not rise for this area since very low
explosives will be used for mining and the machineries to be used shall hydraulic types, it does
not create much noise except the compressor, drilling and jet bummers. The traffic density in the
area is very little. The average noise level in that area is less then 90dB (A) in and around 1Km
radius.
This noise level survey was carried out as per MOEF norms i.e., 1.5m above the ground
level and 2mts away from the noise emit source. At present the noise is only through the
movement of Vehicles in that area. No other significant noise emitting source found.

Ground vibration studies
Hence the vibration source are only through the movement of vehicles where the
frequency is also very less. Hence the vibration is well below the standard permissible by
MOEF. Displacement, Velocity and acceleration of the three kinematics descriptions which are
to be studies to describe ground motion. The peak particle velocity is the more referred since the
area is virgin there is no significant measured velocity found in the area.
Water Environment
Geo Physical investigation was carried out by signal stacking resistivity meter 3 profiling
was carried out in the area applied for lease and 15 Vertical electrical sounding was carried out
to find out the lateral variation and vertical in homogeneity’s it was observed that the water table
is found to be 40mts below ground level and the same was correlated with the wells found at a
distance of 100mts SW & SE of the area.
The water quality monitoring data is enclosed as Annexure No-II
METHODOLOGY AND DATA ACQUISITION: Electric Resistivity Method is well established for delineating lateral as well vertical
discontinuities in the resistive structure of the Earth’s subsurface. The present study makes use of
vertical electric sounding (VES) to delineate the Vertical Resistivity structure at depth.
Schlumberger electrode set up was employed for making sounding measurements. Since it is
least influenced by lateral in homogeneities and is capable of providing higher depth of
investigation. This is four electrodes collinear set up where in the outer electrodes send current
into the ground and the inner electrodes measure the potential difference.
The present study utilizes maximum current electrode separation AB/2. The data from
this survey are commonly arranged and contoured in the farm of Pseudo-section that gives an
approximate of the subsurface resistivity. This technique is used for the inversion of
Schlumberger VES data to predict the layer parameter namely layer resistivity and Geo electric
layer thickness. The main goal of the present study is to search the vertical in homogeneities that
is consistent with the measured data.
For a Schlumberger among the Apparent resistivity can be calculated as follows

Rocks show wide variation in resistivity ranging from 10-8 more than 10+14 ohmmeter.
On a broad classification, one can group the rocks falling in the range of 10-8 to 1 ohmmeter as
good conductors. 1 to 106 ohmmeter as intermediate conductors and 106 to 1012 ohmmeter as
more as poor conductor. The resistivity of rocks and subsurface lithology, which is mostly
dependent on its porosity and the pore fluid resistivity is defined by Archie’s Law,

SURVEY LAYOUT: The layout for a resistivity survey depends on the choice of the current and potential
electrode arrangement, which is called electrode array. Here the present study is considered with
Schlumberger array. In which the distance may be used for current electrode separation while
potential electrode separation is kept on third to one fifth of the same. One interesting aspect in
VES is the principle of reciprocity, which permits interchange of the potential and current
electrode without any effect on the measured apparent resistivity.
EQUIPMENT:
The field equipment deployed for the study is in a deep resistivity meter with a model of
SSR – MP – AT. This Signal stacking Resistivity meter is a high quality data acquisition system
incorporating several innovation features for Earth resistivity. In the presence of random earth
Noises the signal to nose ration can be enhanced by √N where N is the number of stacked
readings. This SSR meter in which running averages of measurements [1, (1+2)/2, (1+2+3)/3 …
(1+2...+16/16)] up to the chosen stacks are displayed and the final average is stored
automatically, in memory utilizing the principles of stacking to achieve the benefit of high
signals to noise ratio. Based on these above significations the signal stacking resistivity meter
was used for (VES) Vertical Electric Resistivity Sounding.
MEASUREMENTS:
Measurements of ground Resistivity is essentially done by sending a current through two
electrodes called current electrodes (C1& C2) and measuring the resulting potential by two other
electrodes called potential electrode (P1& P2). The amount of current required to be sent into the
ground depends on the contact resistance at the current electrode, the ground resistivity and the
depth of interest (Here 1000feet).
DATA PRESENTATION: The field data obtained from a Vertical Electrical Resistivity Sounding is conventionally
plotted on a paper with the help of slum software. (A computer aided diagram).
GEOPHYSICAL DATA INTERPRETATION The geophysical data’s was obtained to study the lateral variations, vertical in
homogeneities in the sub – surface with respect to the availability of groundwater. From the
interpreted data, it has inferred that the area has moderate groundwater potential in the
investigated area.
There are no streams, water bodies or water course within the radius of 500mts and the
rainfall in the area is poor varying for maximum 50 days in a year. The average rainfall is about
850mm as recorded by the meteorological department in the last three years. In some areas of the
District there was no Rainfall recorded for the last 3years. The underground water is portable
without any adverse health effects. There are no boreholes or open wells in the project area
hence the water collected in the area for analysis.
In summer the water drains and the well will be in dry condition. The quality of the water
from well has been analyzed for records. The Limestone mining does not require any water for
its operation. No beneficiation or processing is proposed in the project.
The water required is only for drinking and domestic purpose for which the water will be
brought out from authorized water vendors from the nearby towns.
As water is very vital natural resource and most essential for the survival of human beings,
the same will be consumed only after carrying out scientific studies and will be allowed if it is
within the prescribed standards.
Soil Analysis
As mentioned earlier the area applied for lease is an flat terrain. The soil is the main unit
for the eco system because of the dependence of flora and fauna. As the soil is acidic there are no
thick flora noticed except some common species which are native of the terrain.
The mining activities may have impact on soil. The soil samples were called in 50mts
grid fashion by average and after coning and quartering the same was send to laboratory for
investigation. The following sources are obtained from Agricultural department.
The soil analysis report is as below

Climate
The rain fall data of Salem region in a year is 850mm. Temperature falls between 39°C in
summer and falls down to 24°C in December-January. The wind direction is NE-SW and vice
versa.
Flora and fauna in and around the area
In small mining projects like this which involves very limited operations like secondary
drilling and blasting, Conservation of Flora and Fauna along with ecology does not have
significant impact of the overall eco system. A detail study related to flora and fauna was
carefully observed physically by environmental engineers, Botanist and zoologist. The following
table shows the flora and Fauna available at the region.

Conclusion
The base line studies relents no hazardous levels of dust and noise and prevailing at the
project area. A well implemented environmental Management plan as discussed in the scheme of
mining will help in mitigation the adverse effects due to mining activities.
The project is a small operation were limited activities are being carried on the noise
creating device will be only jack hammer drilling which will always be mitigated in wet
condition to prevent noise and dust in the air. The movement of vehicles is very minimal. The
entire vehicle used will be periodically maintained by well experienced mechanic and kept under
TNPCB standards, emission testing will be carried out periodically and water will be sprinkled
periodically to prevent dust into air. The small quantity of non humus rich surface soil will be
removed and preserved in the boundary barrier to facilitate the Afforestation.
Blasting will be used for heaving effect and not shattering effect hence the fly rock
problem will not arise. The flora in the area is only small bushes as much of the area is flat
terrain. No trees are proposed to uproot for the project and Infect Trees will be planted on
boundary barrier which will act as acoustic sound barriers. Environmental care and attitude of
preventing environment is inducted to the proponent and advice to carry out and mitigate the
minor impacts due to mining. Appropriate persons are advice to get employed to protect the
Environment and Ecology of the area.
