Methane Found In Coal Mine

  • Coal Gas Coal Mine Methane Coal Seam Methane

    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).

    Why Is EPA Concerned About Coal Mine Methane (CMM)?How Is Methane Emitted from Coal Mines?How Much Methane Is Emitted from Coal Mines?What Are The Uses For Coal Mine Methane (CMM)?What Is Ventilation Air Methane (VAM) and How Can It Be used?What Is Abandoned Mine Methane (Amm)?What Is Global Climate Change and Why Should We Be Concerned About It?Methane (CH4) is the second most important greenhouse gas (GHG) after carbon dioxide (CO2). In fact, methane is more than 25 times more potent than CO2 on a mass basis over a 100-year time period. Coal mine methane (CMM) represents wasted emissions to the atmosphere, while capture and use of CMM has benefits for the local and global environment. More information about methane »Top of Page
