CDC - Mining Feature - Coal Mine Explosion Prevention - NIOSH

Mining Feature: Coal Mine Explosion Prevention. 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 ...

CDC - Mining - Explosion Hazards From Methane Emissions ...

Explosions in U.S. coal mines have caused death and injury to miners and destruction of workings since the first reported explosion in 1810. These explosions are caused when buildups of explosive gas and/or dust in the mine are ignited by the presence of a flame or spark. Methane gas is inherently generated and held by adsorption in coal and is ...

232 Historical Perspective Methane Explosions in Coal Mines

Apr 14, 2021  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.

Is Methane Flammable?

And there’s another explosion hazard down in the mines – coal dust. And a methane fire or explosion can then cause a secondary explosion by igniting the dust. And these explosions can be deadly, since 1839 more than 500 fires have occurred in coal mines in the United States, alone, that have claimed 5 or more lives. Methane in mines is no joke.
