Abstract of the Invention The apparatus includes a large-capacity main blower for drawing in air from the face of coal being mined. The main blower draws the air sequentially through a grid which deflects large pieces of coal into a refuse bin, and a main stage of centrifugal filters which separates dust and particles into a stream of dirty air while discharging the clean air back into the mine. The dirty air is routed through a secondary stage of centrifugal filters which is energized by a second blower or pressure unit, the output of which is then routed through a cloth filter stage. Only clean air is discharged into the atmosphere. An air balancing device maintains proper operating pressures in the secondary filter stage for more efficient processing of the dirty air discharge. An adjustable balancing plate maintains proper operating pressure at the collection outlets for the main and secondary filter stages. A device is also included for incorporating rock dust into the main clean air discharge using the power available at the main blower to reduce any hazard.
