  • German Excavation technology in opencast mining, using Bucket Wheel Excavators, Conveyors and Spreaders is used in this Mine for the first time in India.(about 11 times of overburden is to be removed for mining one tonne of lignite).Storm Water Management: evacuating the flood water through float pump mounted on floating pontoons
  • To meet the fuel needs of the 250 MW Independent Power Project put up at Neyveli and additional requirements of NLC's Thermal Power Stations, NLC has developed a new mine, Mine-IA The Mine-IA project is one of the mega projects of NLC that has been completed without cost and time over run.
  • Mine-II had to face problems in the excavation of sticky clayey soil during initial stageThe lignite production in this mine meet the fuel requirements of Thermal Power Station-II. The method of mining and equipment used are similar to that of Mine-I.

  • A brief look onVARIOUS INSTITUTIONS
  • MINE I Area of 26.69 sq.kms. with a reserve of 365 million tones. Production capacity of 10.5 million tones of lignite per annum Feeds lignite to the 600 MW capacity of First Thermal Power Stationand 420MW Thermal Power Station I Expansion. The lignite seam was first exposed in August 1961 and regular miningof lignite commenced in May 1962. Overburden thickness : 50-95 metres, lignite thickness : 10-23 metres.
  • MINE IA Capacity of 3 million tonnes of lignite per annum. Reserve of 120 million tonnes Area of 11.6 sq.kms. The excavation of overburden commenced on 30th July 2001 andthe lignite production commenced on 30th March 2003.
  • MINE II Capacity 4.7 MT of lignite per annum Area of 26 sq.kms. with 390 million tonnes reserves. The initial mine cut was started in April 1981. The lignite seamwas first exposed in September 1984 and regular lignite miningcommenced from March 1985. Overburden thickness : 50-100 m and the lignite thickness : 8 to22m.
  • TPS I Indo-Soviet Collaboration Capacity : 600MW Commissioned with one Unit of 50 MW in May 1962. Presently this Power Station consists of six units of 50 MW each and three unitsof 100 MW each. The Power generated from this Thermal Station is fed to the Grid of TamilNadu Transmission Corporation Limited(TANTRANSCO),the sole beneficiary. From 01.01.2007 Availability Based Tariff is used.
  • TPS IA Capacity - 2 X 210 MW Date of Govt. Approval - 12.02.1996 Lignite Requirement - 2.94 Million Tonnes per annum Lignite source - MINE - I Expansion (4 MT / ANNUM)
  • TPS II Thermal power station - II has been a major source of power to all southernstates of India. Capacity - 1470MW Consists of 7 units of 210MW each. The first 210MW unit was synchronized in March 1986 and the last unit in June1993. Meeting the needs of Southern States viz., Tamil Nadu, Kerala, Karnataka,Andhra Pradesh and Union Territory of Pondicherry
