title: [Bronchopulmonary diseases in workers engaged in deep-mined extraction of copper-nickel ore].
abstract: Examinations were made in 220 male workers exposed to dust-gas (low-silicon dioxide, nitric oxides, and carbon oxide) mixture, physical exercises, and cooling microclimate on deep-mined output of copper-nickel ore. Twenty-eight per cent of the workers were found to have evolving chronic bronchitis that did not substantially affect the patients' working capacity; 3.2% had chronic obstructive pulmonary disease and 1.4% had asthma that had developed before the onset of professional activity. 32.3% of the examinees were ascertained to have individual clinicofunctional disorders that permit their identification as a bronchopulmonary disease risk group to carry out early preventive and rehabilitative measures.
