• Description:
  The United States Federal Coal Mine Health and Safety Act of 1969 limits personal exposure to respirable dust to 2.0 mg/m3. This limit is measured gravimetrically as an 8-hour time weighted average concentration of the respirable coal dust (NIOSH, 1995). If the respirable dust sample contains more than 5 percent silica by weight, the respirable dust standard is reduced according to the formula 10 / (percent silica). Compliance with either the 2.0 mg/m3 respirable dust standard or reduced dust standard maintain silica percentages at or below 100 Fg/m3. Because the continuous miner operator is on or near the continuous mining machine, this person is frequently exposed to the greatest levels of respirable dust. According to data supplied by the Federal Mine Safety and Health Administration (MSHA), over 3100 samples were collected at the continuous mining machine operator in 1998. Nearly 60 percent of the occupational samples contained more than 5 percent respirable silica dust while forty percent of these contained silica concentrations in excess of 100 micro g/m3.
