Capturing Coal Mine Methane :: News :: ChemistryViews

Nov 24, 2018 · Methane is a powerful greenhouse gas. The gas that is released from coal seams during mining has a high methane content, with molecular nitrogen making up most of the remainder. The selective capture of methane over nitrogen would, thus, be useful to reduce emissions from coal mining.

Coalbed Methane - Cretaceous

Coalbed methane is associated with coal deposits, and is found in coal seams. In the past, the gas was the cause of numerous explosions in underground mines. More recently, the gas has been vented to the surface from underground mines. It is only during the last twenty-five years that it was realized that coalbed methane could be used as a ...

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. The methane content in coal seams generally increases the deeper the seam, and also with age.
