Coal Bed Methane

Coal bed methane (CBM) is simply methane found in coal seams. CBM as a source of clean natural gas has immense potential. Methane gas is found trapped in fissures in coal and extraction reduces explosion hazards in mines, thereby reducing safety risks for miners. Thus, coal mine methane, a byproduct of mining operations, can be recovered to provide various types of benefits to a mining company.

Coal-bed Methane (CBM) drainage - From Underground Coal Mines: By: Partha Das Sharma A. Introduction – The primary energy source of natural gas is a substance called methane (CH4). Coal bed methane (CBM) is simply methane found in coal seams. CBM is generated either from a biological process as a result of microbial action or from a thermal process as a result of increasing heat with depth of the coal. Often a coal seam is saturated with water, with methane is held in the coal by water pressure. CBM as a source of clean natural gas has immense potential. Methane gas is found trapped in fissures.
