CDC Mining Feature Coal Mine Explosion Prevention NIOSH

Dec 09, 2011 There are two main types of coalmine explosions: methane and coal dust. Methane explosions occur when a buildup of methane gas contacts a heat source and there is not enough air to dilute the gas level below its explosion point. Likewise, fine particles of coal dust in the right concentration that contact a source of heat can also be explosive.

Firedamp Wikipedia

Firedamp is flammable gas found in coal mines. It is the name given to a number of flammable gases, especially coalbed methane. It is particularly found in areas where the coal is bituminous. The gas accumulates in pockets in the coal and adjacent strata, and when they are penetrated, the release can trigger explosions. Historically, if such a pocket was highly pressurized, it was termed a "bag of foulness".
