Perspectives in current research for control of airborne dust in coal mines.
Ann NY Acad Sci 1972 Dec; 200(1):717-723
The Federal Coal Mine Health and Safety Act of 1969 specified that the maximum allowable concentration of airborne respirable dust in bituminous coal mines in the United States be 2 mg/m3 by the final deadline of December 30, 1975. Although the actual operational deadline for imposition of the 2 mg/m3 level is uncertain because the interim compliance panel (icp) can issue or refuse noncompliance permits that allow operation at an interim 3 mg/m3 level, it is generally expected that the icp will refuse noncompliance permits if the available dust control technology is deemed adequate and is not being fully used. The 1969 act also directed that the Departments of the Interior and Health, Education, and Welfare shall "develop new or improved means and methods of reducing the concentration of respirable dust in the mine atmospheres of active workings of the coal mines." [advanced technology would assist the mine operator in meeting the stringent dust limits imposed by the act.] [the federal Bureau of Mines was assigned the responsibility for designing and implementing a research and development program to provide the advanced technology for reducing coal mine respirable dust.] this paper briefly describes the Bureau's program.
