  • Best Practices for Dust Control in Metal/Nonmetal Mining

    For workers in the metal/nonmetal mining industry, the Mine Safety and Health Administration (MSHA) regulates and monitors exposure to respirable silica dust through personal dust sampling. Recent MSHA personal sampling results indicate that overexposures to respirable silica dust continue to occur for miners in metal/nonmetal mining operations.Controlling Respirable Dust on Longwall Mining Operations,MSHA Inspector Samples Exceeding PEL, 2004 2008 . 2004 –187.9 million tons •Stageloader/Crusher Dust Control •Dust Control in the Headgate Entry •Controlling Shearer Dust Controlling Shearer Dust •Unique to each mine operation •Length –5 to 14 ft
