CLASSIFICATION OF WORKING CONDITIONS IN ORDER TO ASSESS OCCUPATIONAL RISKS

Abstract

The article analyzes the working conditions of miners of an underground mine in the East Kazakhstan region. Based on the data of the certification of workplaces of the Oryol mine, mathematical processing of indicators of production factors was performed. As a result of the research, it was revealed that employees of underground mining sites are exposed to the harmful effects of chemical factors such as silicon dioxide (1.3-1.9 times higher than normal), sulfur dioxide (1.4-1.65 times higher than normal), nitrogen dioxide (1.75-2 times higher than normal) and ammonia (2.1-2.2 times higher than normal). An assessment of the state of working conditions by microclimatic factors showed an excess of air temperature (4-12 times higher than normal) and relative humidity (3-10 times higher than normal) in the workplace. The results of scientific research obtained during the implementation of the scientific and technical program on the topic "Working conditions and occupational risks: classification, categories and grouping criteria in the framework of the transition to a "green economy" (IRN BR22182667) are presented.
