Coal bed Methane (CBM)
Coal bed Methane (CBM), is an eco-friendly natural gas, stored in coal seams, generated during the process of the coalification.
CBM exploration and exploitation has an important bearing on reducing the green house effect and earning carbon credit in preventing the direct emission of methane gas from operating mines to the atmosphere further, extraction of the CBM through degassing of the coal seams prior to mining of coal is a cost effective means of boosting coal production and maintaining safe methane level in working mines.
Having the 3rd largest proven coal reserves and being the 4th largest coal producer in the world, India holds significant prospects for commercial recovery of CBM. Prognosticated CBM resource has been estimated to be around 4.6 TCM.
