Coal dust explosions in underground coal mines are prevented by generous application of rock dust (usually limestone). If an explosion should occur, the rock dust disperses, mixes with the coal dust and prevents flame propagation by acting as a thermal inhibitor or heat sink.
Japanese mining was a rapidly declining industry in the 1980s. Domestic coal production shrank from a peak of 55 million tons in 1960 to slightly more than 16 million tons in 1985, while coal imports grew to nearly 91 million tons in 1987.

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. Coal mine dust is generated by blasting, drilling, cutting and transporting coal.
It was observed that the productivity of surface miner, being the function of depth of cut and cutting speed, was higher in coal over limestone owing to its easier digging conditions in coal.
