Respirable Dust Control Manual for Underground Coal Mines, Volume 2.
NTIS: PB/219-616 Available for Reference At Bureau Libraries :77 pages
The Federal Coal Mine Health and Safety Act of 1969 required each mine operator to continuously maintain the average concentration of dust in the mine atmosphere during each shift to which every miner is exposed at or below 3.0 Mg of dust per cubic meter of air and thereafter at 2 mg/m3 from June 30, 1970, through December 31, 1972. The application of the most successful engineering methods for respirable dust control developed in this country must be utilized by mine operators to maintain dust concentrations within the limits required by law. Work in the past has covered (1) ventilation; (2) water and wetting agents; (3) dust collectors, both dry and wet; and (4) mining equipment design. (With the desired goal of reducing respirable dust in all coal operations, it became mandatory that as much information as possible be assembled, evaluated, and consolidated into a format that could be utilized by all coal operators.) The scope of the survey includes identifying, defining, evaluating, and assembling in meaningful form, all engineering methods developed to control respirable dust in coal mines in the past 20 years.
