• Description:
  Levels of respirable coal mine dust have not been routinely measured in Ukrainian coal mines. Total dust levels have been reported to be 50-600 mg/m3. This abstract reports the results of a joint US-Ukrainian effort to measure respirable dust levels in Ukrainian mines during active production. Personal and area samples were obtained from two Ukrainian coal mines using standard techniques established by the U.S. Mine Safety and Health Administration (MSHA). Samples were taken through an entire shift upwind, downwind, and at the level of the longwall combine operator, as well as intake and return tunnels. Filter cassettes were shipped back to the United States for analysis by MSHA Samples were analyzed for the fraction of respirable silica. Mean respirable dust levels were more than nearly 4 times the US Permissible Exposure Limit PEL with a range of just below the US PEL to more 111aII 10 times the US PEL. Quartz (ug/m3) Respirable Dust Fraction of U.S. PEL. (m m3) /PEL Mean 242 5.31 3.69 Ran e 34-1167 1.66-18.2 0.83-11.6 .US PEL = 2 mg/m3 except when there is> 5% quartz in sample, then PEL = 10 divided by the %quartz. Coal mine dust levels in Ukrainian coal mines are significantly higher than the US PEL This was due in part to high concentrations of quartz found in these mines. Prolonged exposure at these levels could cause significant rates of pneumoconiosis [Description provided by NIOSH]
