A number of gas drainage techniques are developed and practiced in many coal mines of China mainly to minimize outburst risk and reduce gas emission. Dependent upon local geological and mining conditions, one or more techniques may be practiced in a coal mine. A detailed review of the gas drainage practices and challenges in coal mines of China is presented, with particular reference to gas drainage techniques applicable to coal seams of low permeability.
