Coal mine gas (firedamp) is a problematic phenomenon associated with coal mining, as the gas can form explosive mixtures together with air. The main component of the primary coal seam gas is methane in a concentration of 90-95 % the gas develops during the geochemical conversion of organic substances to coal (carbonisation).
