3.0DETAILS OF APPROVED MINING PLAN /SCHEME OF MINING (if any):-
3.1 Date and reference of earlier approved MP/SOM:
The mining plan for fresh grant of mining lease was approved by the Indian Bureau of
Mines vide letter No-TN/TKD/MP/LST-1802-MDS dated 09/04/2012 before grant of mining
lease.
The modified mining plan was approved by Indian Bureau of Mines vide letter No.
TN/TNK/MP/LST-1925.MDS, dated 04.08.2014 and next scheme of mining submission due
was given on 01.12.2016( Refer : ANNEXURE - VI )..
This Scheme of Mining has been prepared and is being submitted under rule 17 (1)
OF MCR 2016 and 23 of MCDR 2017.
3.2 Details of last modifications if any (for previous approved period) of approved MP
/SOM, indicating date of approval, reason for modification
The five years mining plan period is expires on 31/03/2017. The modification of mining
plan is applied based on the condition given in the approved mining plan. The approved
mining plan have been modified for enhancements of proved reserves and decreased in
production program for next three years. The modified mining plan was approved by Indian
Bureau of Mines vide letter No. TN/TNK/MP/LST-1925.MDS, dated 04.08.2014
3.3 Give review of earlier approved proposal (if any) in respect of exploration,
excavation, reclamation etc.
Exploration:
In the previous mining plan there are five bore holes were proposed, but due to
financial crises of Mine owner , the only one wagon drill bore was drilled .
Table – 4
Year Month No. of Wagon drill holes
Total meterage
2014 – 2015 October 2014 1 no. Upto 11 m depth from pit level
The area is very small. The attitude of the limestone band like width and length are
clearly known. Depth persistence of limestone in this area was proved to be 11.0 m from
ground level.
Based on the existing working pit results, the strike and the dip are calculated.
Due to the lack of market demand, non – continuous workings and non – availability
of labour, lack of bulk orders from industries like manufacturing of mineral powder for Soap,
paints, detergent industries etc., the proposed and proved quantity was not mined in the
modified mining plan period. Hence the proved quantity of the approved mining plan will be
taken in the scheme of mining period of 2017 – 18 to 2021 – 22. In this scheme of period,5
No of Diamond drill hole was proposed in the non working area of the mineral band.
Locations of drilled borehole and proposed borehole are marked in the geological plan and
sections . (Refer Plate No. V).
Mine Development:
As it has been specified in the modified mining plan, development work is undertaken to win Limestone. At present, there are five existing pits and its dimensions are given below:
Table – 5
Pit holes Length (M) Width (M) Depth (M)
Pit no – I 26 22 11.0
Pit no – II 40 24 11.0
Pit no – III 66 26 2.0
Pit no – IV 82 36 6.0
Pit no – V 48 22 6.0
Handling of waste:
The topsoil generated during mining would be stored separately and it will be used for
plantation. The side burden and mineral rejects are dumped in the ear marked area.
Exploitation:
In the approved Modified Mining plan for the period (2014 -15 to 2017-18) a total production
quantity of 7,488 Tonnes of Limestone was planned.
The details of year wise planned production Actual production and deviation in production of

ground level.
Based on the existing working pit results, in strike line, from pit no : 4 to south east, pit
no : 5 is mined.
Due to the lack of market demand, non – continuous workings and non – availability of
labour, lack of bulk orders from industries like manufacturing of mineral powder for Soap,
paints, detergent industries etc., the proposed and proved quantity was not mined in the
modified mining plan period. Hence the proved quantity of the approved mining plan will be
taken in the scheme of mining period of 2017 – 18 to 2021 – 22. In this scheme of period, in

k) Furnish detailed calculation of reserves / resources section wise:
Available Reserves of Limestone:
For the purpose of estimation of reserves, cross sectional method has been followed
(Cross sectional area x Length of influence in metres x Depth). Five geological cross
sections are drawn at equal interval and one longitudinal section drawn in the strike length
.
The mine has attained 11.0 m depth and we proposed to put drilled borehole carried
out in the lease area has proved the depth of mineralization upto 11m and hence, the proved
reserves related to UNFC 111 have been considered upto 11 m depth (1m top soil + 10 m
limestone) for calculating the Resource and Reserves as per the UNFC System during the
present scheme period. . (Refer Plate No. V).
The insitu volume in cubic meters was then converted in to tonnage by applying
tonnage conversion factor of 2.6 T/Cu.m. Limestone deposit is always associated with
presence of solution cavities, joints/voids and cavity fillings. This deposit is no exception to
these factors and keeping in view all these conditions a recovery factor of 80% for the
purpose of reserve estimation is considered, Further the drill data i.e core recovery also
substantiates that the core recovery is around 80%. The important factors taken into
consideration for reserve estimation is a recovery factor of 80% based on core recovered
during drilling. A tonnage conversion factor of 2.60 T/Cu.m is considered.
Mineable reserve estimation has been calculated taken into consideration 7.5 m safety
zone from mining lease boundary. From the safety limit a 600 angle has been drawn
(considering an equal bench height and width) and the reserves have been estimated
A recovery factor of 80% for reserve estimation is considered based on the
previous mine workings. The proved Mineable Reserves (UNFC 111 Code) for this plan
period in respect of the recoverable limestone is 82600CUM (214760 tonnes) (80%) for the
present Mining Plan period is 2017 – 18 to 2021 – 22.The reserves were estimated upto
11m depth @ bulk density 2.6 during the previous approved modified plan period.
The information‟s gathered from the excavated pits and drilled boreholes were
correlated to discuss the pre feasibility studies and to calculate the resource and reserves
related to G1, E1, F1 axis of UNFC system.
During this scheme period, the reserves are calculated upto11m depth [0m topsoil +
10m limestone (proved 111)] and the resource and reserves are reassessed on 16.03.2017
as per circular 4/2010 issued by the CCOM, Chennai.
The parameters and dimensions which has been considered for the reserve estimation
is given under Proved Mineral Depth (UNFC 111) = 11m

2.0 MINING:
A. OPEN CAST MINING
a) Briefly describe the existing as well as proposed method for excavation with all
design parameters indicating on plans and sections.
The method of working is an opencast Mining operation. It is proposed to work by
adopting 5 metres bench height and a width of more height of benches of 5metre, with an
ultimate pit slope of 60. The ramp gradient shall be kept minimum of 1 in16. Mining is
performed by open cast method. Systematic mine development and winning of limestone
mineral is planned upto a depth of 36mts. The contract labourers are deployed for manual
segregation for the purpose of loading. The rejects will be handled by the excavators and will
be loaded into10 Ton Tipper. The excavators and the Tippers are engaged on hire basis.
Development:
The main works comprising are - overburden removal, drilling of holes and blasting..The
mining lease area is covered with 0.5 metre to 1.0metre thick soil. During the present scheme
period there is no topsoil would be generated and it is proposed.
Drilling:
Jackhammer drilling is performed in a small holes of 33 mm diameter and the same
will be drilled to a maximum depth of 1.5metre to 2 metre, depending upon the bench height.
Loading:
The bench height has been planned for 5 metre. The limestonewill be loaded
manually..Waste and rejects will be handled by excavator for loading into the tippers of 10
tonnes capacity.
Hauling/Transport ::
The ROM of limestone is straight away loaded into to the tippers by means of machinery and
transported to the temporary stock yard. From that stock yard, the sorted limestone like
magnesia and Siliceous limestone are transported to own industry and needy lime based
industry in Tamil Nadu depending upon their requirements through privately hired lorries.
BLASTING:
The mine is working by manual and mechanical means. The drilling will be carried out by
using jackhammer drilling with 33 mm dia holes. The holes will be charged with special
gelatin and will be detonated by special plain detonators with safety fuse or by electric
detonators. Generally the blast hole pattern in production and development faces will be
having a spacing of 1.6m and 1.2 m burden. The depth of the hole will be 2.0 m. The Powder
factor for production and development will be 7.68 t/kg and average charge per hole will be
0.65 kg..Two holes in a block will be 1.30 kg. The bulk density is 2.6insitufor both production
and development. The calculation for arriving Powder Factor is as follows:
Broad Blasting Parameters: - for manual work
Ordinary of Explosives to be used:
Spacing : 1.6 m
Burden : 1.2 m
Depth : 2.0 m
Bulk density : 2.6 ts/cu.m
Total quantity : 1.6 x 1.2 x 2.0 x 2.6 = 9.98 ts
Charges per hole : 0.650 kg x 2 holes = 1.30
That is 1.30 kg of explosive will generate 9.98 tons of material therefore, 1 kg of explosive will generate.
9.98 / 1.30 = 7.68 tons /kg
Type of Explosives Used:
The drill holes will be charged with special gelatine, detonated with special plain detonator,
safety fuse and with electric detonators.
Storage of Explosives:
The explosives are being drawn from the authorised explosive dealer. The required
quantum of explosives will be planned well in advance and as such there is no scope of
returning the excess quantity or otherwise.
Mechanised operation:
Mechanisation for development work
The mine is working by manual method under „B‟ category .The drilling will be carried out by
using jackhammer drilling with 33 mm dia holes. The holes will be charged with special
gelatin and will be detonated by special plain detonators The holes are connected by
detonating fuse and will be blasted with electric detonators. The blasted materials will be
handled through hired excavators and loaded into dippers. The materials will be dumpedon
the top of the surface, where good grade lime stone and rejects have also been sorted out
manually. The good grade of lime stone will be marketed to the needy industries and the
rejects will be loaded through hired track shovel and dumped in the dump yard. An estimated
production of 1744 CUM (4535 tonnes) per year will be generated both by manual and
mechanical methods.
The generation of rejects during development is shown in year wise production and development schedule.
The existing machinery details:

*Tentative tonnage of the ore may be arrived by computing approximate bulk density
and recovery factor as these data arevariable and may be established on time series.
The insitu volume in cubic meters is converted in to tonnage by applying tonnage
conversion factor of 2.6 T/ Cu.m. Limestone deposits are always associated with presence of
solution cavities, joints/voids and cavity fillings. This deposit is no exception to these factors
and keeping in view all these conditions a recovery factor of 60% for the purpose of reserve
estimation is considered. Further the drill data i.e core recovery also substantiates that the
core recovery is around 80%. The important factors taken into consideration for reserve
estimation is a recovery factor of 80% based on core recovered during drilling. A tonnage
conversion factor of 2.60 T/Cu.m is considered.
II Dump re-handling ( for the purpose of recovery of mineral)

d)Salient features of the proposed method of working:
The method of working is under opencast manual „B‟ category mine considering various
technical parameters like surface topography, continuation of limestone deposits, quality
variations and geo-technical aspects, required rate of production etc. It is proposed to work
this deposit by adopting 7.5m bench height and width of more than the height of benches i.e
more than 7.5 m, with an ultimate pit slope of 60°. Mining is being carried out by open cast
method. Systematic mine development, winning of limestone mineral is planned by taking
into consideration of present economic mineable depth of 36 m in this mine. Based on the
disposition and the width of the limestone body, the ultimate pit limit of is arrived accordingly.
The side wall development will be carried out with the help of
deep hole drilling, blasting and excavation come loader. During production, deep hole
drilling and blasting will be adopted. For secondary blasting jack hammer holes will be
used. Limestone benches will be formed slices of 5m and will be merged as 10m as the
bench reaches the side wall.
The side wall development will be carried out with the help of excavators, tippers and
dozers and the height of the benches in development is being maintained as 10m, which
would be the safe working height of excavators deployed. Specific permission from
Directorate of Mines safety has been obtained for adopting a system of deep hole blasting
and for usages of heavy machinery for digging, excavation and removal of ore etc. under
regulation 106 (2) (b) of Metalliferous Mines Regulation 1961.
From this mine, a quantity of 2325CUM (6046 tonnes) of Limestone per year now
being mined. Only manual mining is being adopted with 32 mm jack hammer drilling and
blasting using 25mm cartridges. Since the deposits occurs in three liner bands of Limestone
with heavy intercalations. This necessitates deploying manual labours for sorting out the
limestone.
The blasted ROM is segregated manually and the sorted out - limestone is loaded
into the 10 trucks for transporting to the lime based industries. A production quantity of
2325CUM (6046 tonnes) per annum have been planned for the period 2017-18 to 2021-22.
The face position at the beginning of first year production and development plan for the five
years are shown in Plate No VI .
The mining will be carried out by means of Open Cast Mechanized method with the
conventional system of mining, which includes drilling, blasting, loading, and transportation.
Proper benches are being formed in accordance with Reg.106 of MMR, 1961. The bench
height in topsoil is about 1m and mineral benches are kept at 5m height. The bench slopes
are maintained at 60° from horizontal in mineral bench and bench width will always be more
than the height i.e. 5m. The haul roads are cleaned and kept in 1:16 gradients for smooth
movement of tippers/ hired trucks used for transportation of mineral.
Ten benches are proposed to form at 5m height and 6m to 7m width with 60o slope.
The mineral rejects is proposed to be dumped separately on the South side of the
mining lease area earmarked. Proper foot- paths will be made between benches for the
easy access of face workers to carry out the ROM from the mine.
The waste is proposed to be loaded manually into tippers or occasionally by loaders to
the dumping yard (when there is a shortage of labour) to the northwest side of the mining
lease area.
Afforestation is proposed in the western side of the 7.5m boundary barrier.
The topsoil is proposed to be dumped separately in the South West in the ear marked area.
If there is any change in the system of mining, the same will be intimated to Indian
Bureau of Mines and the mining scheme will be suitably modified for subsequent clearance
and approval. Please refer the yearwise development and production plans and sections
(Plate No.VI).

Water regime:
Based on the mining experience in the adjacent areas, where the Mining depth has
progressed considerably, the water table found to be at the level of 40 to 45 m below the
surface. The mining operation will go up to 11meters. In the event of any such contingency,
surface dewatering pump will be provided wherever needed.
Flora and Fauna:
Flora:
The study area falls under arid zone. This region is experiencing an uncomfortable
climatic condition with low rain fall. The physiography of the area ranges from bare limestone
outcrop to thin soil profile.The vegetation is characterized with open shrub type of vegetation
with large trees comprising prosopis Juliflora .Azadirachtraindica, Borassus flabellifer
,Acaciaspecies.
The presence of herbaceous flora can also be noticed mostly during monsoon season.
Various types of shrub species adapted to xerophtic condition are visible all around the core
and buffer zone of the study areas.
Mainly acacia and karuveli trees are seen in this area. About 180 teak wood and
Neem trees are planted in this mines area. Other trees Banyan and pungai trees have also
been grown near the office and rest shed of this mine.
Fauna:
Other than domestic animals like cattle, dog pigs, cats no wild endangered species of
fauna are noticed either within the ML area or within the buffer zone.The fauna species are
parrot, dove sparrow hawk, peacock house crow jungle fowl etc.
The reptiles found are also of common variety like viper, toad chameleonand cobra etc.
The insects are honeybee, grasshopper, bugs, scorpion, spider etc.
Quality of Air, Ambient Noise Level and water:
To establish the ambient air quality, air quality, a detailed study was under taken
during different periods.
Air :
Any mining activity is bound to have an impact on the air quality. As air is a vital
ingredient for the health and hygiene of the human beings, great care is undertaken for the
keeping the air quality in control. The most common environmental pollution in air are dust,
SO2, Nitrogen oxide and Carbon dye-oxide. Dust generation in a mine is mainly near the
areas like:
- Working face
- Haul Roads
- Dump site
The primary causes for generation of dust in the mine are due to :
- Vehicular movements
- Excavation, loading and unloading operations,
- Drilling and blasting operations, and
- Wind erosion of dumps.
The poor air quality can cause respiratory ailments, ophthalmic diseases, lung diseases like cough, asthma, bronchitis, TB etc. As already mentioned the existing air quality is good and well within the prescribed CPCB limits. As the mining operations at Kalappaipatti village is at very low key with occasional heavy blasting there will not be any deterioration in the air quality of the area. Besides with adoption of various control measures, such as water sprinkling on haul roads and green belt development around the area will minimize the impact on air quality.
Ambient air quality in the study area is within the permissible limits. Fugitive emissions will
be kept under control through preventive maintenance of mining machinery, water sprinkling
arrangement will be made all along the haulage road to suppress the dust. Wet drilling
system will be adopted at drill sites.
Noise Level and Ground Vibration :: Operation of heavy equipments is drilling and blasting in the mine site may cause minor
increase in the noise level of the area. The noise due to blasting operation lasts for few
seconds. Proper and adequate preventive measures will be taken to control the noise to the
permissible limits. Impact due to higher noise level can cause beingsand can damage
auditory mechanism, if exceeds tolerable limit value.
Besides higher noise level affects the overall efficiency of the workers blood pressure,
permanent hearing loss and mental disorders etc. The noise level study carried out shows
that the noise level is well within the Damage Risk Criteria for hearing loss as specifiedby
Occupational Safety and Health Administration (OSHA) and the Ambient Air quality
Standards in respect of noise.
Blasting operations will be conducting by adopting controlled blasting techniques by
using excel non electric mille second down the hole delay detonators and surface connectors
as well as limiting the number of holes per round and charge per delay as prescribed by
DGMS in the specific permission for blasting. Therefore ground vibrations due to blasting will
be well within the prescribed limits.
Water Quality:
Water quality will not be affected due to mining activity. There will not be any
contamination of ground water in the surrounding areas due to this mining activity.
There is no discharge of effluent or used water from the mine, except at much later stage
when the pit advances below water table requiring dewatering. Hence, no deterioration of
ground water or surface water is anticipated. The quality of discharged water will be within
the Tolerable Limits for Industrial Effluents (IS : 2490), 1981 and the Indian
Standards/Specifications for Drinking Water (IS : 10500), 1983.
Climatic conditions:
1.The area has an average rainfall of 300-400 mm spreading over from of September
to December. This area experiences rain during the North-East monsoon period.
2. The average maximum and minimum temperatures in this area will be 400 to 220 C
respectively.
Human settlement :
Within the core zone there are no settlements and dwellings. Hence he question of
disturbance to the dwellings does not arise due to our the mining operations.
Public buildings, places of Worship and monuments:
There are no public building, places of worships and monuments within the core zone or within the vicinity of the mining lease area.
Sanctuary is located in the vicinity of leasehold:
-Nil-
8.2 Impact Assessment:
Attach an Environmental Impact Assessment Statement describing the impact of
mining and beneficiation on environment on the following :
i) Land use pattern:
Landscape of the area will be disturbed by the mining operations within the ML area.
Land use will change from waste land to open pits in the ML area. The total area in the core
zone are forming waste land which falls in patta lands of the firm. Different item of the mine
lease area is used for excavation, infrastructure, roads, waste dumps, the area is used for
plantation and for green belt development purposes in the adjoining area and hence the
buffer zone area is not affected. The land use of core zone area is also not affected.
The land use of core zone is given in Table.

Total 4.70.0 100%
. The mining activity will not affect any public buildings, monuments of archaeological
importance, as none exist in the vicinity of the proposed mining area.
ii) Air Quality:
Air quality in the study area is within the permissible limits. Fugitive emissions will be
kept under thorough preventive maintenance of mining machinery, water sprinkling
arrangement will be made all along the haulage road to suppress the dust. Wet drilling
system will be adopted at drill sites.
During mining operations, on account of the using jack hammer usage for drilling,
while loading into the tippers, some quantity of dust is bound to be generated depending on
the topography, nature of material handled and climatological parameters like wind speed,
wind direction and stability classification of the area viz location of buffer zone villages. . The
other deleterious parameters of air quality to be considered for the proposed open cast mine
shall be SO2& NO2. From the baseline data generated so far, it is found that the ambient air
quality is within the permissible limits of CPCB.
iii) water Quality:
a)surface water
The water requirement at mines is too limited for the purpose of water sprinkling on
haul roads and for drinking purposes. Hence there will not be any impact on surface water
due to the mining activities.
b) Ground water ::
As far as ground water is concerned, it will not be affected, as the
permeability in the rock formations is very poor. Ground water table is struck at more than
40-45 m depth from the general G.L.The region is predominantly rocky with scanty
vegetation and soil cover. The climate is arid with little rainfall. These factors coupled with
absence of good aquifers are not conducive to rich ground water resources in the area.
However, depending upon the porosity and weathered nature of rocks, weak zones etc.
limited or confined ground water pocket form within varying depths. As such the area has
water tables at depth of 40 to 45 meters. This is based on measuring the depth in the wells
in the study area. The quality of water in general shows moderate values dissolved solids
but low levels of Phosphates, Nitrates, Al, Mn, Cl, Fluoride etc.
iv) Noise Level:
The noise level of the core & buffer zone have been reported in the base line data
which shows that the noise levels are well within the limits as they represent only village
activities. All the villages are located away at the distance of about 700mtrs from the mining
area. The work zone noise levels are less than 90 dba for the people exposed to various
mining operations. The DGMS prescribes exposure limit of 90 dba for workmen in a 8-hour
working shift.
vi) Water Regime:
The terrain of the area has a low relief on the northern side. The area experiences
very scanty rain even during monsoon period. The vegetation is mainly xerophytes like
cactus and no other trees are found to be grown in the area. There are some small water
bodies visible here and there around the area. They are seasonal and dry almost through
out the year.
The water table is about 40 to 45 metres from the surface. When the depth of the
mine reaches 11metre, the water will be pumped out and used for plantation. To minimize the
adverse impact on water regime, the following control measure will be taken. :-
i) Maintain gradient of 1o or 20 for drainage of water on the bench floors and
construction of water drains using local material to prevent wash off and un controlled
descent of water.
ii) Garland drains will be made around the quarry to prevent rain water drain in to the
quarry.
iii) The dumps will be provided with inner slope on top surface and through a system of
drains will be allowed to descend in to surrounding drains so as to minimize the erosional
effects arising out of uncontrollable descent of water.
iv) Mine sump water will be pumped out and used for plantation point for afforestation
work and for agricultural usage. Hence there will not be any leakage of water let outside
the premises and the entire pumped water will be used for plantation.
vii) Acid mine drainage :-
The mining of limestone does not involve any processing operation by using
chemicals. Hence there is no risk at mine site with regard to control of acid mine drainage
iii) Surface subsidence:
Geological formation of this area comprises of hard metamorphic formation and is
.with heavily tectonic disturbed formation due to the folding nature.. Hence due to hard nature
of the formation, there are no possibilities of the area getting subsidence during mining
activity
vii) Socio Economics:
The socio-economic life of the nearby villages have been improved with better
education, literacy and continuous employment. Some people are engaged in seasonal
agricultural activities and thus are not engaged fully.
No house holds are displaced or required to be rehabilitated. Mining will not affect the
crops grown by villages.The mine has employed local people of nearby villages. The
remainingservice sector may raise other further employment to the locals..
viii) Historical Monuments Etc:
There are no public buildings or palaces of importance or monuments within the core
zone.The area is devoid of historical monuments and of any such archaeological
importance.There shall not be any impact on any historical monuments as none of them are
located within 5 km radius.
8.3 Progressive Reclamation Plan:
It is proposed to develop the mine systematically and scientifically to win the entire
limestone within the lease period. The mine is not being refilled as the lease is
workingcontinuously Refilling programme can only be opted after the exhaustion of the
mineral in the adjacent lease also. Besides it is proposed to stabilize the dumps, peripheral
bunds The above progressive closure plan is drawn based on the proved and probable
reserves available.No reclamation and rehabilitation is proposed in the SOM & PMCP since it
is active continuous mine.
Programme of Afforestation:

2019-20 Neem 20 70%
2020-21 Neem 20 70%
2021-22 Neem 20 70%
8.3.1 Mined – Out Land:
The limestone occurring in the mining lease area is of linear body. The average width
of the limestone band is 27 metre. General strike of the deposit is NW-SE with a dip of 70o
SW. Pits are opened along the strike direction and more or less benches are formed parallel
to the strike direction. Depth of the limestone has been proved generally up to 36 mt and
benches will be formed to that level. Hence no reclamation and rehabilitation is proposed in
the Mining Plan &Progressive Mine Closure Plan. By observing systematic and scientific
development of the mine,it can be possible for complete extraction of Mineral.
The mined out pit is proposed to be used as reservoir for storing much needed rain
water. The surrounding areas are dry and experience with low rainfall, any amount of
storage of water will be beneficial for recharging the ground water and to develop flora and
fauna in the adjacent areas.. This reservoir will also be used for Pisciculture development..
The position of the benches and the ultimate pit etc are depicted in Conceptual Plan &
Conceptual Section Plate No: IX.
8.3.2. Top soil Management:
The top soil is block red soil. The generation of top soil for first 5 years is 3167 CUM.
8.3.3. Tailing Dam Management:
There will be no tailing disposal involved due to this mining activity. Therefore no
proposal is made for construction of tailing dams in the mine. the embankment seepage loss
into the receiving environment and ground water contamination etc does not arise.During
mining operation for exploitation of limestone, no other beneficiation process are involved.
Hence the management of tailing dam is not applicable
8.3.4 Acid mine drainage, if any and its mitigation measures :
The mining of limestone does not involve any processing operation by using
chemicals. Hence there is no risk at mine site with regard to control of acid mine drainage
8.3.5 Surface subsidence mitigation measures through backfilling of mine voids or by
any other means and its monitoring mechanism.
The information on protective measures for reclamation and rehabilitation works year
wise may be provided as per the following table:
-Does not arise- There is no back filling during 2017-18- 2021-22. So there is
no information measures for reclamation and rehabilitation works during 2017-18-

II. Exploration:
Primary data
The area has been mapped in a scale of 1:1000. The mining
area has already been excavated to a depth of 11.0 metres. In the previous
approved modified mining plan period there is one wagon drill holes were put in
the existing pit to a depth of 11m in the year of 2014-15. There are 5 Nos. of
existing pits within the lease area. In pit no 3(Band-V) has been already
reached to be a depth of 11m.From the existing pit results, the attitude of band
strike and the dip clearly known out. Hence the proved quantity of the approved
mining plan will be taken in the scheme of mining period of 2017 – 18 to 2021 –
22. In this scheme of period,5 No of Diamond drill hole was proposed in the
non working area of the mineral band.
1. Geological Mapping (Topographical and contour map in 1:1000 scale).The
area is surveyed by total station survey instrument to prepare a geological map
in the scale of 1:1000 showing the various formations, attitude of the deposits
and the reserve position.
2. Geo-chemical Prospecting:
Samples have been tested in the Bombay Test House Pvt. Ltd in Salem to
confirm percentage of Ca CO3. The Chemical analysis report is in Annexure VIII
3. Core drilling and borehole logging :
In this scheme of period,5 No of Diamond drill hole was proposed in
the non working area of the mineral band.
4.Grade:
The limestone is of cem grade and is viable for grinding and burning.
5. Technological prospecting:
The area is very small. The attitude of the limestone band like width
and length are clearly known. Depth persistence of limestone in this area was
proved to be 11.0 m from ground level. Based on the existing working pit
results, the strike and the dip are calculated.
Hence the proved quantity of the approved mining plan will be taken in
the scheme of mining period of 2017 – 18 to 2021 – 22. In this scheme of
period,5 No of Diamond drill hole was proposed in the non working area of the
