After extensive laboratory and in-mine tests, a cost-effective, mineworthy, reduced-noise auger miner cutting head was designed, fabricated, and field tested by Wyle Laboratories, under Bureau of Mines contract H0188065. Compared with standard auger cutting heads, the new heads reduced noise by 10 dBA at the jacksetter's position and 6 dBA at the operator's position. The reduced-noise heads were able to cut and load coal as effectively as the standard heads and are now being used successfully in several underground mines. Mine shops can easily modify the standard auger cutting heads to produce the reduced-noise design.
