Abstract: The purpose of auxiliary equipment at coal mining enterprises is to create and maintain the required operating conditions for excavator-dump truck systems. Poor performance of auxiliary equipment has a significant negative impact on key technical and economic indicators of the enterprise's production process efficiency. For example, poor motor grader performance results in increased diesel fuel consumption by dump trucks due to a reduction in their operating speed due to the deterioration of service roads, which leads to additional maneuvering and braking/acceleration cycles. Poor bulldozer performance results in deterioration of the excavator work platforms, leading to their sudden failure due to unstable operation. An assessment of the performance of auxiliary equipment at several Russian coal mining enterprises revealed that this type of equipment, and consequently the processes in which it is used, is currently viewed as secondary, resulting in poor performance accounting and monitoring. This attitude toward secondary processes is reflected in the fact that the wages of workers involved in them are significantly lower than those of workers in primary processes. Furthermore, wages for workers in auxiliary processes are typically not linked to their direct labor output, unlike those of workers in primary processes. This wage ratio results in the actual utilization of auxiliary equipment being, on average, half that of primary equipment. This article presents methodological recommendations for improving the organization of auxiliary equipment operations, based on the identified functional relationships between the utilization of this equipment and the technical and economic performance of the enterprise, followed by the development and implementation of accounting and compensation systems for auxiliary equipment operators.
