27 Ch4 Coal Mining Handling

2.7 CH4 Coal Mining Handling - IGES

2003-2-25 · Methane (CH4) is produced during coalification (the process of coal formation). Only a fraction of this remains trapped under pressure in the coal seam and surrounding rock strata. This trapped methane is released during the mining process when the coal seam is fractured. Methane released in this fashion will escape into the mine works, and will eventually escape into the atmosphere.
