Simple coal workers' pneumoconiosis (CWP) is defined by the presence of small lung opacities that develop after at least ten years of exposure to coal dust. The disease is rarely seen in miners who have spent less than 20 years underground. Workers are often asymptomatic with normal pulmonary function studies. Chest x-ray findings resemble those of simple silicosis. Studies of miners with simple CWP have not shown increased mortality rates. [LaDou, p. 328-9] [Harber, p. 365] [Rosenstock, p. 1082] Approximately 3% of the currently employed underground coal miners in the US have evidence of CWP by chest x-ray compared to 33% in 1970.
