Hazardous Gases: Methane • MineARC Systems

Coal Mine Methane (CMM) is a blend of air and methane released from rock strata as a direct result of mining activities. Methane trapped within a coal seam emerges in a mine after the removal of layers of a coal face. Additionally, the gas can seep out of vents from abandoned mines, or appear after a rock collapse from a post-mining area.
