How the Six Cleanest U.S. Longwalls Stay in Compliance.
Taylor CD; Jankowski RA
Mining Congress Journal 1982 May; 68(5):37-40
The objective of a U.S. Bureau of Mines program was to conduct dust surveys at six longwall sections having double-drum shearers, which were regularly in compliance, and to identify the dust control techniques that were the most effective. As each of the mines selected had a record of regular compliance with federal dust standard, all sampling was "short-term" (often less than 30 minutes) and no attempt was made to relate the survey results to dust sampling results obtained by the companies for compliance purposes. The sampling procedures used during this survey were developed jointly by the Bureau of Mines and Foster-Miller Associates, Inc. in addition to monitoring dust levels, measurements were also taken throughout the shift to monitor airflow along the face, and water usage on the shearer. This program was a cooperative effort of the Bureau of Mines and the Mine Safety and Health Administration.
