Modification of Bureau of Mines Berc Rock Dust Meter.
NTIS: PB 257 385 :5 pages
The Bureau of Mines has improved a mine dust incombustibles analyzer originally developed at the Bartlesville (Oklahoma) Energy Research Center (BERC). This analyzer provides quick, accurate analysis of the percentage of incombustible material present in dust samples taken from mine ribs, roof, and floor so that costly overdusting may be eliminated while still maintaining a proper level of incombustibles. The changes being effected on the present design of the BERC Model IV rock dust analyzer should simplify its operation and calibration procedures, resulting in increased accuracy.
