Coal Workers’ Pneumoconiosis is a lung disease caused by inhaling coal mine dust. Although some miners never develop the disease, others may develop the early signs after less than 10 years of mining experience. According to recent studies by the National Institute for Occupational Safety and Health (NIOSH), about one of every 20 miners participating in our program has X-ray evidence of some pneumoconiosis. cwhsp-resource-list.pdf Publication date from document properties.
