NLC INDIA LIMITED ('Navratna' - A Government of India Enterprise) MINE-II PRE-FEASIBILTY REPORT FOR MINING OF LIGNITE & ASSOCIATED MINERALS (Silica sand & Ball clay) PRE-FEASIBILITY REPORT FOR MINING OF LIGNITE & ASSOCIATED MATERIALS AT MINE-II 1. INTRODUCTION: NLC India Limited, (NLCIL) formerly (Neyveli Lignite Corporation limited) is Navaratna, a Government of India Enterprise registered under Indian Companies Act, 1956, engaged in commercial exploitation of the Lignite deposit available at Neyveli region. NLCIL is engaged in commercial mining of the Lignite deposit available at Neyveli region in Tamil Nadu as well as in Rajasthan. Four lignite mines having a combined production capacity of 30.6 MTPA feeding lignite to thermal power stations having a combined generating capacity of 3240 MW. NLCIL is operating 1000 MW Coal based Thermal Power Station as joint venture project with NLC Tamilnadu Power Limited. The total power generating capacity of NLCIL is 4240 MW. In addition, NLCIL is also supplying lignite (1.9 MT/Y) to an Independent Power Plant (TAQA) of 250 MW generation capacity. A New Neyveli Thermal Power Station (NNTPS) of 1,000 MW generation capacity at Neyveli is under commissioning as a replacement for the existing TPS-I of 600 MW. In the Non-Conventional Energy Sector, 51 MW wind power project and 640 MW Solar Power Project has been commissioned in Tamilnadu while another 709 MW at Neyveli is under implementation stage. NLCIL has signed a JV agreement with UP Government to establish a 1980 MW Power Station (3 x 660MW) at Ghatampur, Uttar Pradesh and the project is at the execution phase. The below tables show the NLCIL existing operating projects. Another 3200 MW (4 x 800 MW) coal based Power Plant is planned in Odisha utilizing the coal from Talabira mine.

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. 2.

As per the Rule 24-A(6) of the Mineral Concession Rules, 1960, if the renewal application of mining lease submitted twelve months before the date of expiry of the lease period, the period of lease shall be deemed to have been extended by a further period till the State Govt. grants the lease. 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. INDEX MAP OF MINE-II 4. Land use The Project area for Mine-II project is 7193.975 Ha which includes mine area, external dump area and infrastructure. In addition 159.645 Ha land is envisaged for formation of Re-settlement centers for displaced people. The present land use breakup details is given below: LAND USE DETAILS TILL 31.03.2019 BREAK-UP Sl. No. Land use Area in Ha 1 Area mined out 2355.61 2 Area reclaimed 874.50 3 Area afforested 670.50 4 No. of tree plantations 1320650 5 External OB Dump 1242.35 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.
