Respirable coal mine dust sample processing
The Federal Coal Mine Health and Safety Act of 1969 established mandatory dust standards for coal mines. Regulatory requirements for complying with the provisions of the Act were prescribed in Title 30, Code of Federal Regulations, Parts 70 and 71, which were published in the Federal Register on April 3, 1970, and March 28, 1972, respectively. These standard and sampling requirements of coal mine operators, along with a description of the laboratory which was established to process respirable coal mine dust samples collected in accordance with these requirements, were published in MESA Informational Report (MESA, the acronym for the Mining Enforcement and Safety Administration, was changed to MSHA, the acronym for the Mine Safety and Health Administration, in 1977). These standards and regulatory requirements continued under the Federal Mine Safety and Health Act of 1977 until November 1980, when major regulatory revisions were made in the operator's dust sampling program. This paper describes the changes in the respirable coal mine dust sampling program and the equipment and procedures used by MSHA to process respirable coal mine dust samples collected in accordance with regulatory requirements. 10 figs., 1 tab.
