Mine gas | mining | Britannica

Mine gas, any of various harmful vapours produced during mining operations. The gases are frequently called damps (German Dampf, "vapour"). Firedamp is a gas that occurs naturally in coal seams. The gas is nearly always methane (CH 4) and is highly inflammable and explosive when present in the air in a proportion of 5 to 14 percent.White damp, or carbon monoxide (CO), is a particularly ...

Coal Gas | Coal Mine Methane | Coal Seam Methane

Coal mine methane (CMM) is a type of gas present in active, working mine sites. This gas is extracted from the air in the coal mine helping improve safety and preventing uncontrolled release of methane to atmosphere. CMM is a mixture of methane & air released during the process of coal mining and must be vented for safety reasons.
