Abstract: In the industrial sector of the country's economy, particularly in the coal industry, a continuous trend of increasing mining equipment costs has emerged, while coal prices fluctuate significantly. This circumstance necessitates corresponding changes in mining equipment operating procedures to ensure high profitability. An assessment of mining equipment operating procedures at coal mining enterprises revealed that, over many years, factors have accumulated and gradually intensified, leading to an increased risk of deteriorating operator control of the equipment and, consequently, increased production costs. These factors include, for example, reduced operator qualification requirements due to staffing shortages, reduced operator responsibility for the technical condition of the equipment due to their exclusion from equipment maintenance and repair, etc. Poor operator control of the equipment manifests itself in equipment operating at peak loads and irrational operating parameters, leading to breakdowns and reduced productivity. To reduce the risk of deteriorating equipment control quality, it is necessary to develop and maintain activities that ensure continuous monitoring of equipment operator qualifications, taking into account ongoing changes in the environment. This article presents the positive experience of SUEK-Khakassia LLC employees in assessing and improving the qualifications of hydraulic excavator operators
