The large continuous mining machines use a rotating cutting drum studded with toothlike bits to rip coal loose from the coal seams before scooping it into a conveyer system. The cutting process and the falling, tumbling coal create continuous clouds of dust that obscure the machine operator's sight and cause health and safety risks.
