1Mining Leases in IndiaTotal area under mining leases in India is about 1 million ha. Out of this about 0.4 million ha area is under coal mines.This does not include individual leases under 10 ha area each.Area-wise Distribution of Mining Leases*(Indian Bureau of Mines, Nagpur, 2010)Frequency group area (ha)# of mining leases% of leasesArea (000 ha)% of area0-50868283841650-10089086613100-20043646012200-50028138617500199221142All groups10488100507100* Excluding fuel, atomic and minor minerals

Impact of Mines and Mine-spoils and Environmental DamagesHypothesis of Reclamation Conducting post-mining soil and mine-spoil inventories define the establishment of ecosystem stability. Understanding successful germ-plasm selection; characterizing physical and chemical properties of soil, mine-spoils and overburden; conserving and maximizing soil moisture storage through rainwater harvesting; and evaluating plant community sustainability are important. Criteria for Evaluating Mine-land ReclamationStabilization of surface materials through appropriate landscape reconstruction, and Establishment of long-term, sustainable vegetation communities.

In general, a silvi-pastoral system is being designed for reclamation as it complements the needs of local population.What is Required?Case Study 1: Reclamation of Lignite Mine-spoilLocation: Giral Village, Barmer, RajasthanRainfall: 265 mm per yearType of Mining: OpencastWater Harvesting: MCWHSAmendments: Fine Sand, Caliche and FYMPlant Species: Indigenous, Naturalized and Exotic Leguminous and Indigenous Non-leguminous (15 species) Coal/Lignite Mining (Giral,Rajasthan)Before Reclamation

After Reclamation
