  • Methane production from coal by a single methanogen

    effects of methane produced from coal mines Methane associated with coal beds is an important global resource of natural gas. Much of the methane in coal comes from microbial methanogenesis. Mayumi et al. characterized a strain of Methermicoccus shengliensis that, unexpectedly, is capable of making methane from the dozens of methoxylated aromatic compounds found in a variety of coal types (see the Perspective by Welte).

  • Coal mine methane | Climate Technology Centre & Network

    Methane is the primary constituent of natural gas and is stored within coal as a result of the coalification process whereby plant material is converted to coal. Due to coal mining activities (and subsequent pressure decrease in coal seams), methane is released from the coal and surrounding strata. This leads to the build-up of methane in mines, which potentially creates an explosive hazard.
