Coal dust Wikipedia

Because of the brittle nature of coal, coal dust can be created during mining, transportation, or by mechanically handling coal. It is a form of fugitive dust. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier to handle. However, coal dust is hazardous to workers if it is suspended inField Evaluation of the Coal Dust Explosibility Meter,FIELD EVALUATION OF THE COAL DUST,2The Pittsburgh Research Laboratory was part of the U.S. Bureau of Mines,A recent coal dust particle size survey,Survey of Fugitive Dust From Coal Mines:,EPA908/178003 SURVEY OF FUGITIVE DUST FROM COAL MINES FEBRUARY, 1978 U.S .
