Respirable coal mine dust is a hazard in underground and surface coal mines and in coal-processing facilities. It is a mixed dust, consisting mostly of coal, but can also include silica, clay, limestone and other mineral dusts. The composition of coal mine dust varies with the coal seam, the composition of the surrounding strata and mining methods.
Dust explosion risks may be even more serious in plant rooms containing the milling machinery than in the machin-ery housing itself. The hazard arises from bad housekeeping, which allows dust to accumulate on ledges, ceiling beams, and other surfaces. After an initial dust explosion in or around milling equipment, a second explosion can occur
