The Federal Coal Mine Health and Safety Act of 1969 defines CWP as a "chronic dust disease of the lung arising out of employment in an underground coal mine." Progressive massive fibrosis (PMF) is a complicated form of CWP and is generally associated with breathlessness, chronic bronchitis, recurrent chest illness, and even heart failure.
Jul 20, 2018· NIOSH has operated the CWHSP and tracked the burden of black lung disease in underground coal miners since 1970. Through the Program, coal miners are offered periodic chest x-rays to detect early signs of black lung. For this study, NIOSH researchers looked at x-ray data collected by the CWHSP from working underground miners during 1970 to 2017.
