Commonly used mining techniques to extract coal
In case of strip mining, coal seams are reached by removing the surface above them. The surface, which is referred to as overburden, is removed in long strips in this coal mining technique. The overburden taken out from the first strip is deposited outside the mining place. This process is referred to as out-of-pit dumping. The void resulting

CHAPTER 4 FUGITIVE EMISSIONS
The geological processes of coal formation also produce methane (CH4), and carbon dioxide (CO2) may also be present in some coal seams. These are known collectively as seam gas, and remain trapped in the coal seam until the coal is exposed and broken during mining. CH4 is the major greenhouse gas emitted from coal mining and handling.
