Abstract
Methane is a natural by-product in the formation of coal and is present, in varying quantities, in all underground coal mines. The presence of methane presents an imminent hazard since it can mix with air to form explosive gas mixtures (5 to 15% methane in air mixtures are flammable) which can devastate an entire mine if ignited.
