Objective. To carry out a comprehensive hygienic assessment of the working conditions of miners of underground polymetallic ores mining, taking into account various technological operations to predict the risk of the development of health disorders and to optimize labor. Materials and methods. The object of the study was the miners of the underground ore mining of the Zhezkent mining and processing plant (MPP) of Kazakhmys Corporation LLP in the East Kazakhstan region. Comprehensive hygienic studies on working conditions of various professional groups included an evaluation of microclimatic parameters, illumination, vibroacoustic factors in accordance with the Methodological Recommendations Hygienic criteria for the assessment and classification of working conditions according to the indicators of harmfulness and danger of the working environment factors, severity and intensity of the labor process. Results. The results of the hygienic studies of the working conditions of miners of underground polymetallic ore mining of the Zhezkentsky MPP of the Kazakhmys Corporation demonstrated a number of unfavorable production factors. Thus, the relative air humidity varied within 96.1%, the dust content in the air of the working area exceeded the maximum permissible concentration (MPC) by 4.5 times, the noise and general vibration indicators exceeded the MPC from 11dB to 28dB. Conclusions. The results of a comprehensive hygienic assessment of the working conditions of miners of the underground polymetallic ore mining of the Zhezkentsky MPP allowed us to establish that the working conditions of engineers for mining equipment management by the degree of harmfulness corresponded to the 3rd class of the 3rd degree, and the work of miners of auxiliary professions-to the 3rd class of the 2nd degree.
