Methane in Underground Mines • MineARC Systems

13/12/2018  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 layers of a coal face are removed. Additionally, Methane can seep out of vents from abandoned mines, or appear after a rock collapse from a post-mining area.³ . Due to its volatile nature, Methane poses an extreme ...
