estimating methane emissions from coal mines - global

Apr 29, 2021 · Formula. The CH 4 emissions for a coal mine can be calculated with the following formula: . Annual CH 4 (in million cubic meters) = Production * Gas content at mining depth * Emission factor coefficient. Example for a deep, underground bituminous coal mine, with a depth of 465m: Production: 5 million tonnes per annum; Gas content at mining depth: 13.4 m 3 /tonne

geological and geotechnical aspects of underground coal

Aug 05, 2009 · Longwall mining is the most common of the underground coal mining methods used in Australia. It suits sites where coal seams are thicker, wide and have a consistent coal profile with gentle dip. In longwall mining, large rectangular sections of coal are identified and removed in one continuous operation (Trueman et al. 2009 )
