WhatsApp: +86 18203695377Coal seam gas, also called coal bed methane, refers to naturally occurring methane in coal seams. The gas is held on coal surfaces and trapped by water pressure in the gaps and cracks in the coal seams. In order to allow the gas to flow, water is drawn away from the seams to release the gas into a gas well. The Victorian Government banned the ...
