Effects Of Methane Produced From Coal Mines

Methane is the primary constituent of natural gas and is stored within coal as a result of the coalification process whereby plant material is converted to coal Due to coal mining activities and subsequent pressure decrease in coal seams methane is released from the coal and surrounding strata This leads to the buildup of methane in mines which potentially creates an explosive hazard
