Abstract: The analysis of the volume of investments and depreciation of the Kuzbass excavation fleet is carried out using the management company Kuzbassrazrezugol as an example. It has been proved that the volume of investments is insufficient, and the excavator fleet is being updated at a slow pace. This calls into question the possibility of increasing coal production according to the plans of the Government of the Russian Federation and reduces the competitiveness of Russian coal enterprises in the world market. The general tendency to fail to meet planned standards and to reduce technical readiness ratios and the use of the calendar time fund negates the effect obtained by the introduced new units. The possibility of increasing productivity through the use of existing resources in the form of increasing the utilization rate of working hours and increasing the efficiency of the use of excavators within the working time is revealed.

Key words: Kuzbass open pit mining excavator equipment fleet depreciation technical readiness coefficient use of working time
