Best Practices For Dust Control In Coal Mining

U.S. underground coal mine workers. • During 1980–2005, over $39 billion in CWP benefits were paid to underground coal miners and their families. • Recent x-ray surveillance data for 2000–2006 show an increase in CWP cases. Nearly 8% of examined underground coal miners with 25 or more years of experience were diagnosed with CWP.
