Firedamp is flammable gas found in coal mines. It is the name given to a number of flammable gases, especially 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".

Mar 17, 2018· As coal mining developed in Europe during the 17th and 18th centuries, severe mine explosions became common. It was soon discovered that the origin of the explosions was the ignition of mixtures of flammable gas, or firedamp and air, which accumulated in the mines. Firedamp is essentially methane liberated from coal when pressure is released.
