Cdc 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 contact a source of heat can also be explosive.
