approach to elimination of the coal dust problem is to add stone dust to the roof, ribs and floor to render the coal dust inert. In addition, many mines use explosion barriers which are designed to be activated by the pressure wave in front of an explosion, and flood the area with either water or stone dust, which renders any suspended dust inert.
