The article presents the hygienic evaluation of the dust factor as the main risk factor in underground and surface mineral mining. It contains data on concentrations of dust and toxic gaseous components for workers of main professions at mines operating in different regions and characterized by specific working environment. Physical and chemical characteristics of mine aerosols are also given, and their potential contribution to the risk of respiratory diseases development is emphasized. It is stated that occupational morbidity of underground workers in three last years ranged from 94.9 to 116.9, and that of surface miners – from 20.6 to 22.8 per 1000 workers, who had passed medical examination. The share of dust-related diseases of underground workers accounted for 21.3 – 25.7%, while that of surface mine workers – for 6.1 – 16.1%. Pneumoconiosis ranks first in the list of respiratory occupational diseases, which morbidity rates are the highest among drillers, drift miners, sinkers, production face workers having 15 – 20 years of service. The authors propose a system of technological, engineering, hygiene and sanitary, as well as medical and preventive measures for the prevention of dust-related respiratory diseases of miners.

Key words: hygienic evaluation of the dust factor, ore mines, dust-related respiratory diseases
