Mine gas, any of various harmful vapours produced during mining operations. The gases are frequently called damps (German Dampf, “vapour”). Firedamp is a gas that occurs naturally in coal seams. The gas is nearly always methane (CH4) and is highly inflammable and explosive when present in the air Name the common gases found in coal mines following a mine fire or explosion? A: Carbon monoxide, Carbon Dioxide, Methane, Oxygen, Nitrogen, Hydrogen, and other hydrocarbons. Methane (CH 4) Methane is a colourless, flammable, non toxic gas that has no odour in its pure state. Methane is the major component of natural gas and is found in varying levels in most coal and shale deposits. It is a simple asphyxiant due to its ability to displace oxygen from air where sufficient quantities exist. The Underground Coal Mines sector consists of all underground coal mines that liberate 36,500,000 actual cubic feet of methane (equivalent to approximately 17,579 metric tons CO 2 e) or more per year. Facilities in this sector include both underground coal mines under development and those categorized by the Mine Safety and Health Administration as active mines. This conference paper was originally published as Lunarzewski, L, Coal mine goaf gas predictor (CMGGP)], in Aziz, N (ed), 10th. Underground Coal Operators' Conference, University of Wollongong & the Australasian Institute of Mining and Metallurgy, 2010, 247-256. 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). Australia’s market-leading experts in underground mining gas calibration and analysis. Providing specialised technical support to more than 90% of all NSW and QLD coal mines. We offer a range of services to all industries where the accuracy and precision of calibration and service of gas detection devices is critical to safety and production.

Underground coal mining releases more methane than surface or open-pit mining because of the higher gas content of deeper seams. Total national emissions
