Abstract: Global coal deposits are often associated with trapped methane, whose nature and composition are similar to that of the natural gas. Compared to coal, this trapped methane is a superior as well as cleaner fuel but its fugitive emission from coal mines is also a serious environmental threat. In coal mines, sudden leakage of trapped methane leads to air contamination and gas explosion resulting into catastrophic accidents. Also, methane is a potential GHG and its fugitive emission has several adverse effects on environment such as global warming, climate change and so on. Since, GWP of methane is twenty-five times more than carbon dioxide and coal mines act as a potential source of methane emission, therefore methane handling becomes a primary responsibility for the coal dependent countries of the world for reducing the atmospheric emissions. The drainage of trapped methane from the coal seams prior to mining can be a possible solution towards reducing its fugitive emission and to utilize the same as a promising source of clean unconventional energy. The present paper discusses the environmental as well as the economic advantage of pre-mining methane drainage using the case study of highly gassy coal seams of Jharia coalfield.
