Coal Seam Gas, Coal Bed Gas, Coal Mine Methane - Brochure

Coal mine degasification was originally developed to improve worker safety. The methane, if not captured, is usually vented to the atmosphere through the use of exhaust fans. The potential danger to the environment through mines gas and its main constituent methane (CH 4, 25-60%) can be reduced significantly considering methane has a global warming potential (GWP) 21 times that of CO2.
