Coal mine methane | Climate Technology Centre & Network

Methane is the primary constituent of natural gas and is stored within coal as a result of the coalification process whereby plant material is converted to coal. Due to coal mining activities (and subsequent pressure decrease in coal seams), methane is released from the coal and surrounding strata.

Methane | EME 444: Global Energy Enterprise

Methane (CH 4) is a gas that forms naturally in the process of coal formation.It is also a potent greenhouse gas, with a global warming potential (GWP) over 20-30 times greater than CO 2 over a 100 year period, despite the fact that it remains in the atmosphere for a shorter time (about 12 years vs. hundreds or thousands of years for CO 2).When coal is mined, methane is released.
