摘要

Coal mining industry in India plays a very important role in country's economy - more than 70% of the total power generated in the country is from coal, and considering the total energy requirement, coal contributes more than half. During 2004-05, for power generation alone about 300 million tones (Mt) of coal was consumed which is about 80% of the total coal production of the country. After nationalization of the coalmines in 1972 and 1973, coal production grew at a very first rate from a level of around 78 Mt in 1973-74 to 407 Mt during 2005-06. It has been envisaged that at the end of XI plan (2011-12) coal demand will be in the order of 620 Mt and 780 Mt at the end of XII plan (2016-17). Keeping all the environmental consequences in mind, coal will be the major source of energy input in India. Opencast mining operations have a number of irreversible impacts on the surrounding environment and ecosystems. Mitigation measures commonly adopted in mined out areas are: compensatory afforestation/plantation, reclamation, rehabilitation and ecological restoration. In this paper, overview of land degradation due to coal mining in India, important statues relevant to ecorestoration and future research areas are identified. How to select plant species for ecorestoration programme? Should direct showing of tree seeds better than sapling for Ecorestoration? What are difficulties for Ecorestoration? Current ecorestoration status of some mines like KD Heslong (CCL) and Chirimiri mine (SECL) are also discussed. Details of monitoring and aftercare of restored sites also given at the end.
