Can mines cause explosion? Coal mine explosions are generally caused by either methane or coal dust. Methane gas is a byproduct of coal. It can build up over time in coal mines when there are not enough other types of gases to dilute it to prevent an explosion. .. Explosions happen when the methane comes in contact with a heat source.
