dust explosion in coal grinding
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.

Combustible Dust : OSH Answers
The basic requirements for a dust explosion to occur is that combustible dusts are suspended in air and are ignited. In practice, for a dust explosion to occur, a number of conditions must be met including: The dust must be combustible and release enough heat when it burns to sustain the fire. The dust must be capable of being suspended in air.
