Methane gas is another component of coal, produced from methanogenesis. Methane in coal is dangerous, as it can cause coal seam explosions, especially in underground mines, and may cause the coal to spontaneously combust. It is, however, a valuable by-product of some coal mining, serving as a significant source of natural gas.
