Abstract: The main disadvantages of the existing system of technical maintenance and repair of mining equipment at the mining enterprise (GDP) are considered, the main of which is an increase in labor and material costs as a result of untimely preventive and restoration work, as well as the discrepancy between their volume and content to the actual technical condition of mining equipment. The experience of some mining enterprises, where a program for monitoring the technical condition of mining equipment is already being implemented, is considered. The main advantages and results obtained from the development of a monitoring system for mining and transport equipment (GTO), which allow to obtain a certain effect from its use, are analyzed. The results of the survey of a large group of excavators are presented, which made it possible to group the machines into several groups: satisfactory condition, unsatisfactory, good and unacceptable. The processes of reducing the technical resource of mining equipment during its operation have been studied, based on this, economically feasible service lives of parts and assemblies of rope excavators and wheel loaders have been established. The main defects and irregularities that can cause the mining machine to stop due to the failure of any system, ag-regatta or node are indicated. Recommendations are given on the organization of a department at the GDP, or a group that has assumed the function of planning, accounting and reporting on the results of the monitoring of mining equipment.
