Coal Workers' Health Surveillance Program

“The first priority and concern of all in the coal or other mining industry must be the health and safety of its most precious resource – the miner.” Federal Coal Mine Health and Safety Act of 1969, amended 1977

The Federal Coal Mine Health and Safety Act of 1969 (as amended by the Federal Mine Safety and Health Act of 1977) is intended to protect the health and safety of underground coal miners. This Act directs NIOSH to study the causes and consequences of coal-related respiratory disease and, in cooperation with the Mine Safety and Health Administration (MSHA), to carry out a program for early detection and prevention of coal workers' pneumoconiosis. These activities are administered through the Coal Workers’ Health Surveillance Program (CWHSP), as specified in the Federal Regulations, 42 CFR 37, “Specifications for Medical Examinations of Underground Coal Miners.”

NIOSH staff located at the Division of Respiratory Disease Studies (DRDS) in Morgantown, WV, are responsible for conducting the CWHSP. The CWHSP consists of three components:

  1. Coal Workers' X-ray Surveillance Program (CWXSP). Information about free chest x-rays provided for underground coal miners. Who pays? What is Coal Workers' Pneumoconiosis? Black Lung? When? Where? Frequently Asked Questions and Answers.

  2. National Coal Workers' Autopsy Program. When a coal miner dies, the family may arrange for a free autopsy. The results may help support a "black lung" benefit claim, and also help scientists and medical doctors learn more about coal workers' pneumoconiosis (CWP) or "black lung" disease.

  3. NIOSH B Reader Certification Program. NIOSH B Reader certification is granted to physicians who demonstrate proficiency in the classification of chest x-rays for the pneumoconioses using the International Labour Office (ILO) Classification System.

In light of the observed onset of advanced pneumoconiosis among younger coal miners, and the apparent regional clustering of rapidly progressive cases, NIOSH, in collaboration with MSHA, has developed, staffed, and implemented the ECWHSP. This page contains more information about the program and survey summaries.

The Work-Related Lung Disease (eWoRLD) Surveillance System, produced by the National Institute for Occupational Safety and Health (NIOSH), presents up-to-date summary tables, graphs, and figures of occupationally-related respiratory disease surveillance data on the pneumoconioses, occupational asthma and other airways diseases, and several other respiratory conditions. For many of these diseases, selected data on related exposures are also presented.
