1.0 PROJECT DETAILS:
The applicant , Mine-II is a existing operating mine with a capacity of 15 MTPA to cater
Thermal Power Station - II & Thermal Power Station - II Expansion. of 1970 MW. It is one of
the important project at National level.
In order to expose lignite, overburden thickness of 45m to 112m has to be removed as
waste. The Overburden consisting of lateritic loam or blackish grey alluvial clay with Kanker,
Cuddalore group of sedimentaries, Sporadic occurrences of hand ferruginous and siliceous
sandstones, unconsolidated sandstone with admixture of clay and silica sand occurring
immediately above lignite and alternate layers of sand and clays below lignite. During the
process of overburden removal and Lignite excavation, economic bands of clay and silica sand
occurring within these formations were found which are segregated towards conserving
natural resources.
For lignite production capacity of 15 MTPA of Mine-II, Environment Clearance from
Ministry of Environment and Forest was obtained during December, 2002. The corresponding
Environmental Impact Assessment report prepared by M/S Vimta labs earlier considered
lignite as the main product and did not consider the recovery of clay & silica sand which occurs
sporadically. Now it is proposed to include the clay & silica sand as an associated product with
lignite, for which an amendment in EC is required incorporating the recovery of clay & silica
sand. Hence this pre feasibility report is prepared for submission to MOEF & CC.

3. Need for the project and its importance to the country and or region
Mine-II is an operating unit and feeding lignite to Thermal Power Station-II & II
Expansion.
The exploration studies carried out and our past mining operation has showed that in
addition to lignite occurrence, sporadic occurrence of silica sand and ball clay was noticed.
There is demand in market for silica sand used in glass making and ball clay used in making
ceramic materials. In addition to lignite, recovery of silica sand and ball clay also will bring good
return to State as well as Central Governments in the form of royalty and taxes. Therefore this
proposal is very much essential in the perspective of conservation of these valuable raw
materials, which otherwise would go as waste to the dump yard.

Reclamation and afforestation of overburden dumps is being carried out progressively
as per approved Mine Closure Plan.
5. Demand-supply gap:
There is a good demand in market for silica sand used in glass making and ball clay used
in making ceramic materials. Mining these materials will increase State as well as Central
Governments income in the form of royalty and taxes and contributes to nation’s growth by
meeting market’s demand.
6. Imports vs. indigenous production
Indigenous production benefits the community through direct and indirect employment
creation. There is no import of this silica sand and ball clay at present.
7. Export possibility
There is no export of this quality of silica sand and ball clay at present as there is
demand in the country itself for these products.
8. Employment generation:
At present about 4,256 number of persons employed inclusive of both direct employment
and employed through contractor. There is no additional manpower requirement for
recovery of silica sand and ball clay.
9. PROJECT DESCRIPTION
Mine II project area : 7193.975 Ha.
Mining area : 4122 Ha.
Lignite Mining Capacity : 15.0MTPA
Details of alternate sites & Environmental considerations and Basis of selecting the proposed
site:
Lignite deposition is site specific and mining in this area is inevitable. Hence, no
alternate site could be considered. In order to exploit lignite, the overburden removal is
carried out as a waste material during the removal of overburden ball clay and silca sand also
mined out.
10. Geology
10.1 Regional Geology:
Geologically, the selected mining area and the surrounding area belong to the Upper
Miocene age of the Tertiary & Recent. The sequence of the geological formation in the mining
area and for the region is given below:
TABLE SHOWING STRATIGRAPHY OF NEYVELI AREA
11.0 Geology of the Area:
Geology of the second mine cut area is similar to the first mine cut area in the sense that
in both the areas lignite is associated with Tertiary formations of upper Miocene age and
stratigraphically similar formations, in the same sequence, are met within both the areas. i.e.,
sandstones, clays, lignite and aquifer sands. These formations are designated as “Cuddalore
group of sedimentaries”.

There is no indication of any major structural features like folds, faults, etc., within
the “Cuddalore” in this area.
Sub-surface lithology of Neyveli Lignite Field is mainly based on the exploratory
borehole data. The investigations of the exploratory boreholes as well as the irrigation
wells established in the area form the main basis for the interpretation of the sub-surface
aspects of the area. The Tertiary formations are exposed in the northern edge of the
present and proposed Expansion area of Mine II, while the alluvial deposit covers the rest
of the area. The total thickness of the overburden material ranges between 45 and 112
m.
The uppermost layer consists of either lateritic loam or blackish grey alluvial clay
with Kanker and succeeded by Cuddalore group of sedimentaries. Sporadic occurrences
of hand ferruginous and siliceous sandstones are observed which requires selective
blasting for uninterrupted mining. The unconsolidated sandstone formation with
admixture of clay occurring immediately above lignite, generally ranges between 3 and 15
m thickness (semi confined aquifer). Lenses of economically mineable quantity of silica
sand is occurring at the bottom of this formation. The lignite underlies this formation and
varies in thickness from 4 to 24 m. In most of the area 2 to 3 m of thick clays separate the
lignite seam from the underlying confined aquifer, which contains alternate layer of sand
and clays. The ball clay and silica sand is of sporadic occurrence in nature in the selected
lignite mining area.
11.1 Reserves:
Lignite:
The general dip of the lignite bed is in East to South -East direction with 1 in 70 to 1
in 100 gradient. The basin is devoid of any geological disturbance like fold or fault. The
lignite is mainly of single seam, but splits into two or three seams at the eastern boundary
with inter burden consist mostly of clay and fine sand. Lignite thickness varies from 4 m to
24 m.
The Geological Reserve of the Mine-II is 622 MT and mineable reserve in selected
mine area of Mine II is 595.69 MT. Lignite so far mined out upto 31.03.2019 is 304.27 MT.
The Reserve details and basic Project Parameters of the Mine-II block are given in
the in the below table.

Reserves of Silica sand and Ball clay :
Silica Sand:
A layer of sandy formation having a thickness of few meters to 15.0 m is occurring
just above lignite sporadically. This formation form the semi confined zone in Mine-II.
Lenses of economically mineable quantity of silica sand is occurring at the bottom of this
sandy formation. However the silica sand is mixed with clay matter, iron oxides and
sulphur bearing mineral (marcasite matter). It shows dull greenish in color.
A drawings showing the mode of occurrence of silica sand and ball clay deposits in
the mining area is shown in plate No.1 & 2.Plate No.1
Silica sand A lenzoid body of Silica sand deposit occur just above lignite seam in Mine-II Plate No: 2
Analyzed silica sand samples collected from the exposed area revealed SiO2 content of
around 90.0% or less and also contains impurities like oxides of iron, marcasite (Sulphur as
SO3) and clay particles. The analytical results of the silica sand is enclosed in Annexure-I.
Because of sporadic occurrence of silica sand, the estimated reserve of silica sand in the
lignite mining area is about 32.37 LT. However the reserves may vary depending upon the
reserve estimation by drilling exploratory bore wells in the closed intervals during the lignite
mine face advancement.
Ball Clay:
The ball clay mostly reported as clay in the bore holes below lignite and in most of the
bore holes, sand layers exists immediately below lignite. Which suggests ball clay is of sporadic
occurrence in nature in the selected lignite mining area. Because of sporadic occurrence of ball
clay, the estimated reserve in the lignite mining area is about 26.88 LT. However the reserves
may vary depending upon the reserve estimation by drilling exploratory bore wells in the
closed intervals during the lignite mine face advancement.
11.3 Lignite / silica sand mining with process details:
The Overburden is being removed in 5 benches viz, New Surface, Surface, Top, Middle
and Bottom by Specialized Mining Equipments like Bucket Wheel Excavator, Belt Conveyor,
Tripper and Spreader. During progressive mining, the overburden (OB) excavated for in order
to mine lignite is dumped as Inside & Outside Dumps. These dumps are reclaimed by proper
terracing and stabilized and top soil which is excavated from mine advancing front is spread
over these refilled/ dump area for afforestation.
Lignite excavation is carried out by Bucket Wheel Excavators, transported to pit head
lignite bunker by belt conveyors and stacked by stacker. From bunker it is reclaimed and
dispatched to Thermal Power Stations by belt conveyors.
The silica sand is available in the bottom of the Bottom bench. When the mine
advancement taking place by cutting the overburden through Bucket wheel excavator, the
silica sand will be handled and loaded in the conveyor and separately stocked in the dumping
side. From dumping side, the silica sand is re-handled using conventional mining equipments
and transported to the Stock Yard located in the surface. The method of mining depends on
the site condition, mode of availability of silica sand.
The ball clay is associated with lignite as pockets at places and it could be mined using
conventional mining equipments like shovel and transported through dumpers. After weighing
separately, silica sand and ball clay are transported by dumpers to stock yard at surface for
storage before selling to the interested parties.YEARWISE MOVEMENT PLAN OF MINE-III WITH EXTERNAL DUMP YARD
Sequence of mining:
Continuous opencast mining method by deploying SME-Specialized Mining Equipment
comprising of BWE-Bucket Wheel Excavator, Conveyors, Tripper Car, Spreader, Stacker &
Reclaimer for removal of overburden and lignite mining. For mining and transportation of silica
sand and ball clay, SME/ CME will be used as per availability of reserve and site conditions with
stock yard at surface for storage before selling to the interested parties.

Mining of these materials silica sand and ball clay will be commenced upon receiving approval from
concerned authorities. Depending upon the demand and reserve the above mentioned schedule may vary
accordingly.
11.4 Raw Material Required Along with Estimated Quantity, Likely Source, Marketing Area of Final Product’s
Mode of Transport of Raw Material and Finished Product:
No raw material is required as this is a mining activity. Only diesel would be required for
transportation of vehicles and supporting HEMM and generators in case of emergency. The mined lignite
does not require beneficiation.
The quality of ball clay is good and no beneficiation is required. Silica sand is of low grade and cannot
be used for glass making in its raw form. So for conservation of mineral, it is proposed to wash the
impurities to use in glass and other industries.
11.5 Resource Optimization/ Recycling and Reuse Envisaged in the Project:
Resources like Explosives, Diesel Oil, Machinery, Land, Power and Water are fully optimized to
minimize unnecessary losses during the process of excavation and supply of lignite to the customers. The
resources which are used in the mining are recycled by various methods. Spent oil from transformers, will
be sold to the authorized vendors. The ground water pumped for safe mining is being used for power
generation in linked thermal power stations. Mine sump water collected at settling pits shall be discharged
from mine through pumps and used for dust suppression, mining activity and irrigation to surrounding
villages. Silica sand and ball clay which are valuable raw materials will be conserved for beneficial industrial
use instead of dumping as a waste material.
11.6 Availability of Water its Source, Energy / Power Requirement and Source:
Water:
The seepage water and the rain water collected in the mine sump is being utilized as industrial water
required for washing, sprinkling on mine roads for dust suppression, for watering the mine site plantations
and for irrigation of agricultural lands in the region. The drinking water is being supplied from bore well and
stored in overhead tank near the facilities area and distributed through pipe lines to different facilities
area for drinking and domestic purposes. The ground water pumped out to depressurize the upper
confined aquifer for safe lignite mining is being utilized at interlinked thermal power stations for power
generation.
Power:
The total power requirement of Mine-II & Mine-II Expansion for 15.0MTPA Stage is about 340MVA
and its availed from the nearest NLCIL Power source i.e from TPS-II. Mine Sub Station with 12 transformers
of 8 X 30 MVA & 4X 25MVA are installed and in operation.11.7 QUANTITY OF WASTES TO BE GENERATED (LIQUID AND SOLID) AND SCHEME FOR THEIR MANAGEMENT /
DISPOSAL:
It is an operating mine and the following best practices are adopted for the waste management.
Solid waste:
The overburden so far excavated upto 31.03.2019 in Mine-II project is 1891.92 is dumped at inside
decoaled area as back filling and partial quantity was dumped at the external dump area.
As a part of environment restoration, these dumps are reclaimed by proper terracing and stabilized;
top soil is spread over and afforested. Plantation includes fruit bearing trees, flowering plants and
medicinal. Integrated farming & aquaculture is also being carried out in these afforested lands. Artificial
ponds, deer park & boat house are established. In Mine-II, mine closure activities are performed as per the
approved Mine Closure Plan approved by MOC. NLCIL has been awarded the prestigious Paryavaran
Puraskar Award in appreciation of the outstanding work done in the area of reclamation.
In the remaining mining area, about 1510 Mm3 of overburden is to be removed in the remaining
period of mine life and accordingly will be reclaimed and afforested as per Mine Closure Plan.
Waste water:
Adequate drainage systems are available in the mining, service centre for allowing the water to flow
in the predetermined path. Check wall, gully chute, edge bund, retaining wall, silt traps etc., are available to
arrest washout from the mine dump area during rainy season. All along the mine roads drainage will be
provided and benches will be properly sloped so as to avoid stagnation of water. The waste water
generated in the service yard and canteen are treated and the treated water is used for gardening.
With above measures no adverse impact is envisaged on the surface water quality in the proposed
lignite mining project. The quality of effluents is monitored regularly.
The water used for the process of washing the sand is allowed to settle in the setting pits for
removing Suspended Particulate Matter.
Hazardous waste:
The hazardous waste generated in the mine like used engine oil, used gear oil, used brake oils and
other lubricants are stored in separate drums/cans and sent to disposal through authorized-recyclers.
Air pollution Control:
Emissions from machines run by burning Fossil fuel (diesel) are controlled by properly maintaining
the vehicles. Dust emanated from the mining operations is controlled by sprinkling water.
Noise pollution Control:
Specialized Mining Machineries (SME) are used for excavation of OB and lignite. These are noise
generating machinery for which noise proof air conditioned cabins is provided for operator and the noise
levels are within the range of 60-90 dB (A). The effect of the shock/vibration from blasting is controlled at
the mine surface level itself by restoring to the use of milli-second delay action detonators and milli-second
detonating relays .There is therefore, no danger of vibration being carried on the nearer
structures/Buildings.
Sewerage system
Sewage generated from office premises is treated through septic tanks and soak pits. Well
established ETP is functioning in the township to treat the sewage from colony.12.0 REHABILITATION AND RESETTLEMENT PLAN

14. PLANNING BRIEF
Mining Method:
In Mine-II & Mine II Expn. project, BWE’s, Conveyors, Spreaders (SME Technology) are deployed for
the removal of overburden and lignite excavation. The excavated lignite transported to Lignite Stockyard by
conveyor system. For excavation by BWE, where ever hard rock is encountered drilling and blasting
operation is being carried out with adherence to norms. The excavated overburden is being refilled by using
spreaders in the mined out area. After Top soil spread, the backfilled area will be biologically reclaimed and
afforested to restore to pre-mining condition.
For mining and transportation of silica sand and ball clay SME/ CME will be used as per availability of
reserve and site conditions with a stock yard at surface for stacking/ storage before selling to the interested
parties. For mining these ball clay and silica sand no additional equipments are required.
Assessment of Infrastructure Demand (Physical & Social)
The existing road and other infra structure facilities are enough to meet out the requirements.
Amenities/Facilities
All facilities like office, statutory buildings, water, power, medical facilities etc are already available in
the project.
14. 1 PROPOSED INFRASTRUCTURE:
No additional infra structure required as this a existing mine in operation.
15.0 PROJECT SCHEDULE & COST ESTIMATES
The balance life of the project is 20 years for the targeted production of 15.0 Mt/annum. The total
mine capital cost is about Rs 3639.33 Crores and there is no additional investment required for this
amendment proposal. Project schedule of lignite, Silica sand and ball clay as mentioned above.16.0 ANALYSIS OF PROPOSAL (Final Recommendations)
The lignite mine project has already given direct as well as indirect employment facilities to the
Project affected families and villagers and employment through contractors. Lot of employment
opportunities have been created in the form of service providers, petty contracts, hiring vehicles etc. In
addition to above, silica sand and ball clay recovery from mine will provide business opportunities to
transporters, traders and employment opportunities in glass manufacturing and ceramic industries.
