Milled limestone, referred to as "rock dust" by the coal industry, is an additive used for safety in underground bituminous coal mines. The particles of the milled limestone mix with coal dust to prevent a potential explosion.
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.
