The article addresses the issue of providing personal protective equipment, taking into account the risk of exposure to harmful factors of production during the extraction of copper ore in ore deposits located at great depths, i.e., underground mining. The working conditions of miners are characterized by a complex of harmful production factors, which include, above all, high dust and gas pollution of the air and a heated microclimate. The investigation revealed that workers in underground mines are exposed to the harmful effects of chemical factors. The evaluation of working conditions based on microclimatic factors showed an excess of air temperature (4-12 times) and relative humidity (3-10 times) in the workplace. Mathematical data processing has shown that the distribution of dangerous and harmful factors is subject to polynomial dependence. Mathematical data processing showed that the distribution of hazardous and harmful factors is subject to polynomial dependence. Increased air temperatures at a number of production sites, air pollution with dust and gases require a revision of the list of personal protective equipment, depending on the class of working conditions, taking into account the established standards for output. The authors provide recommendations for the introduction of a new range of personal protective equipment, depending on the presence and degree of exposure to harmful factors of production.
