In case of mining project, a copy of mining lease/letter of intent should be given

I. The Mining lease was granted Proceeding vide. G.O. (3D) No.29 Industries

(MMA-2) Department Dated: 03.04.1998.

II. The Scheme of Mining was approved by the Regional controller of Mines, Indian

Bureau of Mines, Chennai vide TN/PBR/LST/MS-854.MDS, Dated: 07.06.2013.



(ii) Brief description of nature of the project

The opencast manual mining operation is proposed by the formation of benches. Three

benches with 2.5m height and 2.5m width proposed slope maintained as 60º from horizontal. The

limestone in the area under consideration is fine grained coral limestone and is mainly made up

of calcite with sub-ordinates amount of quartz and silicate minerals. The mine lease area is

1.14.0Ha; the life of mine is twenty years.

The proposed quantity of Limestone (90%) of ROM mined for during this scheme period

(as in the Scheme of mining) would be about 113486Ts and anticipated waste is about 7792Ts

(3948Ts of Mineral rejects (10%) Ts of ROM + 3844Ts of Over burden) up to depth of 6m during this

scheme period of five years.

The waste is calculated as 10% of ROM. This include fragments, chips, etc., the mined

waste would be generated and dumped along the Northern side of the pit. Water requirement for

the proposed project for drinking purpose, dust suppression and afforestation would be around

1.0KLD which will be taken from nearby villages.

(iii) Need for the project and its importance to the country and or region

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.

This project will give employment opportunities to 7 members directly and 5 members

indirectly.

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) 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, 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.

There are many possibilities for export the Limestone to foreign countries especially to Japan,

Malaysia etc., as the Limestone is one of the mostly important manufacture of cement industries

in the world.

(vii) Domestic/Export Markets

The applicant after will fetch a good domestic market as mentioned earlier. The applicant

does not have any other mine in Tamilnadu. Limestone utilized in lessees own mini cement

plant. Limestone is mainly for production of cements. The cement is expected to growth of

infrastructure/housing sectors of the domestic market.

(viii) Employment Generation (Direct and Indirect) due to the project

It is proposed to deploy about 7 employees directly and indirectly about 5 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.

(iii) Details of alternate sites considered and the basis of selecting the proposed site, particularly

the environmental considerations gone into should be highlighted

The manual opencast mining method is proposed in the area for excavation of Limestone

with 6m depth. The mine 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 1.14.0 Ha. It is proposed for production (90%) of

ROM is about 113486Ts by open cast manual mining by deploys jackhammer drilling and

blasting, manual loading of Limestone from pithead to processing plant.

(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 a plain and flat ground sloping towards South. The topsoil is to a

thickness of about 2.0m block cotton soil. It is a dry area and only seasonal cultivation is carried

out. The main crops are groundnut, maize and other cereals. In some places agriculture is done

with lift irrigation. Water table is touched at a depth of 15m in rainy season, ie. During North-

East monsoon and at 25m in summer months.

Wind direction is NE to SW and vice-versa. The temperature in summer rises above 400C

and fall down to 250C in winter months. There are no national monuments, places of worship or

archaeological interest, public buildings, permanent structures near the area. There is no river,

tank or reservoir, sanctuary or forest near the area.

Geology of the area

The sedimentary formation in Olaipadi West, belongs to the cretaceous system and rest

over archaean formations. The strike of the formation is ENE – WSW to NE – SW direction with

low dips towards southeast. The thickness is about 14 mtrs. The Archaean contact over which

these formations rest is somewhat sheared and at places malachite staining can be observed. The

archaean are represented mainly by charnockite. At the contacts, these rocks have been lease had

giving the appearance of granite-gneiss. The strike of the sedimentary is unconformable with that

of the archaeans and coral limestone overlies the archaeans and the exposed portion near Kallai



is more or less or a crescent shape. It is about 400mtrs. Long and ranges in width is an ore body

contains numberous boulders of charnockite which show some degree of rounding and

weathering. The size of the boulders is large and ranges from 8cm to 1meter. It is evident that the

transport of these boulders could not have been forma for way distance of their source as seen

from the size, degree of rounding and low weathered characteristics. The coral limestone is over

lapsed y are naceous limestone which at many places passes into clicarious sand stones by the

predominance of course grains. The deposits further away from these constitute Ariyalur stage of

cretaceous system.

The following geological sequence can be made out in this area.

The area limestone occurs below the topsoil cover with thickness of about 1.0m.

Method of Mining:

Mining would be carried out by the manual opencast method of working. Since the daily

rate of production is very limited, no heavy earth moving machinery is required. The Mining

operation would be done in a systematic way by forming benches with all safety aspects as

stipulated in the Mines Act, Mines Rules and Metalliferous Mines Regulations.

Machineries like Jackhammer drilling, tractor mounted compressors and blasting by

developing the benches at 2.5m height and 2.5m width. The drilling is carried out with

jackhammer of small diameter (30-32mm) at shallow depth and blasted with class 2 slurry

explosives with charge ratio as 0.7 to 0.9. The mine would be operated with manual laborers

with one shift only.

Open Cast Working:

It is proposed to carry out mining operation by opencast manual method.

There is two existing pit in the lease area and its dimension is 67m x 27m x 6m (d) &

26m x 16m x 6m (d). There will be three benches proposed in limestone with 2.5m height, 2.5m

width and slope maintained at 60º from horizontal. Proper haul roads will be maintained for the

easy access of men and machinery to the temporary stock yard and to the dump. It is proposed to

start mining present scheme period mining operation carried out from existing pit in Eastern to

Western, to a maximum depth of about 6m.



It is proposed to dump on the Southern and Northern side during this period and the

recovery of percentage of the mineral is 90%. Top soil already preserved along the boundary

barrier and it will be utilized for afforestation. Afforestation is proposed in the 7.5m boundary

barrier on the lease area.

Limestone Mine

BASE LINE STUDIES

The base line a study is prepared for Olaipadi (west) 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. Saravana Mines and Minerals have applied for Limestone Mine lease for over an extent

of 1.14.0Ha in S.F.No. 202/2k (Part) of Olaipadi (west), Kunnam Taluk and Perambalur

District. The area proposed for mining for the present Scheme period is about 0.15.0Ha 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 is almost plain and flat

ground 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 lively

Poultry farm industry, Automobiles sectors 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.

Topography





East monsoon and at 25m in summer months.

Wind direction is NE to SW and vice-versa. The temperature in summer rises above 400C

and fall down to 250C in winter months. There are no national monuments, places of worship or

archaeological interest, public buildings, permanent structures near the area. There is no river,

tank or reservoir, sanctuary or forest near the area.

Geology of the area

The sedimentary formation in Olaipadi West, belongs to the cretaceous system and rest

over archaean formations. The strike of the formation is ENE – WSW to NE – SW direction with

low dips towards southeast. The thickness is about 14 mtrs. The Archaean contact over which

these formations rest is somewhat sheared and at places malachite staining can be observed.

The archaean are represented mainly by charnockite. At the contacts, these rocks have been

lease had giving the appearance of granite-gneiss. The strike of the sedimentary is

unconformable with that of the archaeans and coral limestone overlies the archaeans and the

exposed portion near Kallai is more or less or a crescent shape. It is about 400mtrs. Long and

ranges in width is an ore body contains numberous boulders of charnockite which show some

degree of rounding and weathering. The size of the boulders is large and ranges from 8cm to

1meter. It is evident that the transport of these boulders could not have been forma for way

distance of their source as seen from the size, degree of rounding and low weathered

characteristics.

The coral limestone is over lapsed y are naceous limestone which at many places passes into

clicarious sand stones by the predominance of course grains. The deposits further away from

these constitute Ariyalur stage of cretaceous system.

The following geological sequence can be made out in this area.

Age and groups Rock Type

Recent and quarternary Kankar and muram -----------------------Unconformities----------------------- Cretaceous Coral limestone Archaen (Boulders of Charnockite) The area limestone occurs below the topsoil cover with thickness of about 1.0m.

Vegetation

The lease area is almost plain and flat ground. 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 ground nut, paddy etc., 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

monitoring data is enclosed as Annexure No-I.

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.

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

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

ρa = G∆V

I

∆V = potential difference between receiving electrodes

G = Geometric Factor.

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,

ρr = Fρw = a Øm

ρw

ρr = Resistivity of Rocks

ρw = Resistivity of water in pores of rock

F = Formation Factor

Ø = Fractional pore volume

A = Constants with values ranging from 0.5 to 2.5

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

800mm 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 almost plain and flat ground. 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

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 plain and

flat ground. 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.
