BioCNGCoal Mine Methane

SHARE

Coal mine methane is released from the coal and surrounding rocks by mining. In underground mines, it can create an explosive hazard to coal miners, so it is removed through ventilation and degasification systems. In abandoned mines and surface mines, methane might also escape to the atmosphere through natural fissures.
