NIOSH Testimony on Coal Mine Health Research by E. J. Baier, June 29, 1977.
NIOSH 1977 Jun:12 pages
This testimony discussed coal mine health research efforts and technical assistance programs offered by NIOSH in support of protecting the health and safety of the miner. NIOSH has conducted research directed toward protection of life and health, detection of respiratory impairment, and prevention of occupational diseases of coal miners; established coal mine health standards; and assured the availability of medical examinations for underground coal miners. Morbidity and mortality studies indicated that coal mining continues to be one of the most hazardous occupations in the United States, causing excessive numbers of cases of chronic bronchitis and airway obstruction, coal workers' pneumoconiosis, deaths due to accidents and assorted respiratory diseases, and excessive numbers of lung cancer and stomach cancer deaths. The third round of the National Study of Coal Workers' Pneumoconiosis was scheduled to begin in fiscal year 1977. A prospective study of 400 new miners was underway to determine whether miners exposed to coal mine dust levels at or below the 2mg/m3 limit will develop significant lung impairment. The introduction of diesel powered equipment into coal mines was also of concern due to possible health effects of long term exposure to a combination of coal dust and the gases and vapors of diesel exhaust. An international workshop was being held to identify and address research gaps in the effects of diesel engines in underground coal mine operations. Hearing loss among miners has also been the subject of research. Specifics of the medical examination program for miners and the national coal workers' autopsy study were reviewed.
