  • Coalbed methane Wikipedia
    OverviewHistoryReservoir propertiesExtractionEnvironmental impactsCoalbed methane producing areasCoalbed methane, coalbed gas, coal seam gas, or coal-mine methane (CMM) is a form of natural gas extracted from coal beds. In recent decades it has become an important source of energy in United States, Canada, Australia, and other countries. The term refers to methane adsorbed into the solid matrix of the coal. It is called 'sweet gas' because of its lack of hydrogen sulfide. The presence of this gas is well known from its occurrence in underground coal mining, where it presents a serious safet
