Effects Of Methane Produced From Coal Mines

effects of methane produced from coal mines

Coalbed methane (CBM or coal-bed methane), coalbed gas, coal seam gas (CSG), or coal-mine methane (CMM) is a form of natural gas extracted from coal beds. In recent decades it has become an important source of energy in United States, Canada, Australia, and other countries.

Coal seam methane | World Coal Association

Methane (CH4) is a gas formed as part of the process of coal formation. When coal is mined, methane is released from the coal seam and the surrounding disturbed rock strata. Methane can also be released as a result of natural erosion or faulting.

Coal Mine Methane: A Review of Capture and Utilization ...

Coal mine methane (CMM) is a term given to the methane gas produced or emitted in association with coal mining activities either from the coal seam itself or from other gassy formations underground. The amount of CMM generated at a specific operation depends on the productivity of the coal mine, the gassiness of the coal
