Abstract
Extraction of minerals with noise and vibration to be a priority harmful occupational factor, is one of the industries with a high risk of workers’ health, disorders. This is an occupational morbidity rate. In accordance with the regulatory and methodological documents, an assessment of the a priori and a posteriori occupational risks related to the impact of the noise-vibration factor was carried out for workers of the main occupations of the largest enterprises extracting fuel, energy and ore minerals of the Republic of Bashkortostan.An analysis of occupational health risks for workers has shown a rather high a priori risk, since the general hygienic assessment of working conditions is within the limits of Сlasses 3.2–3.4. Levels of occupational risk in accordance with occupational disease index ranged from «high» for vibrational disease in occupational groups of drifters, rig drivers, excavator drivers to «above average» for sensorineural hearing loss in installers, underground mining machine drivers, excavator drivers and aggregates. Based on the studies, measures have been developed aimed at reducing the levels of exposure to the noise-vibration factor and maintaining the health of workers engaged in mining.
