CH4 Coal Mining Handling IPCC
The amount of methane (CH4 ) released during coal mining depends on a number of factors, the most important of which are coal rank, coal seam depth, and method of mining. Underground coal mining releases more methane than surface or openpit mining because of the higher gas content of deeper seams. Total national emissions from
