History of Illinois Coal Mine Disasters 1941 to 1950

The explosion failed to propagate, and was confined to a small localized section, as a result of recent and liberal applications of rock dust by the generalized method and by bag suspension; and both methods were effective in smothering the combustion of the coal dust. Rock dust will effectively prevent the propagation of coal combustion, but it does not prevent the ignition of methane gas nor .

3 Coal dust represents an explosion hazard in underground coal mines, which often can be mitigated effectively through a proper rockdusting program. The practice involves applying an inert rock dust material to the surfaces of an underground coal mine and maintaining sufficient quantities so that the incombustible content of the combined coal dust, rock dust, and other dust is not less than 80 .

COAL DUST EXPLOSIONS Coal dust, when suspended in the air as a cloud, is capable of bursting into an explosion and propagate it, even in the absence of firedamp. For a coal dust explosion to take place: Coal dust must be of a composition which includes sufficient VM. Coal dust should be of necessary fineness.

A second explosion took place during recovery operations about 8 hours later. No one was injured, but it was decided to seal off the entire section, in which 17 bodies remained. Apparatus was used extensively. The first explosion was propagated by coal dust but was localized by rock dust. The seals were opened and the bodies recovered 10 days later.
