Coal Workers’ Health Surveillance Program (CWHSP)

• The Federal Coal Mine Health and Safety Act of 1969, amended in 1977

• To develop improved health and safety standards to protect the health and safety of the Nation’s coal and other miners

Coal Workers’ Health Surveillance Program (CWHSP)

• Federally mandated worker medical monitoring program for underground coal miners

• Eligible miners can obtain periodic chest radiographs

Purpose of CWHSP

• Early detection and prevention of coal workers’ pneumoconiosis (CWP)

• Provide health information to miners

• Study the causes and consequences of respiratory diseases associated with coal mining

• Surveillance (e.g., monitor trends and patterns)
