Abstract: Relevance of the work: Evaluation of the results of the functioning of the operating system of the equipment of the technological complex for a number of advanced mining enterprises in Russia showed that the interaction of its two main subsystems: technical use and maintenance, is characterized as mismatched. The mismatched interaction of the subsystems under consideration determines the operation of equipment with disproportionate performance and the level of its performance. This leads to an overrun of production resources due to the occurrence of sudden failures and unjustified costs for the repair maintenance of equipment. It has been determined that ensuring coordinated interaction between the technical use subsystem and the equipment repair subsystem can significantly reduce the costs of equipment operation and significantly increase its productivity. The development of these reserves requires the development of methodological tools for measuring the actual and possible effectiveness of the interaction between the technical use subsystem and the equipment maintenance subsystem.
Purpose of the work: development of a methodological toolkit for assessing the effectiveness of the interaction of subsystems for the technical use and repair maintenance of the equipment of the technological complex of a mining enterprise.
Research methods: review of scientific research, analysis of technical indicators of the results of the operation of the equipment operation system of the technological complex, mathematical modeling, production experiment.
Results: formulas for assessing the levels of interrelationship and complementarity between the subsystems of technical use and maintenance of the equipment of the technological complex of a mining enterprise have been developed and are proposed for use. The results of the application of the developed formulas in the conditions of the Chernogorsky open-pit mine of LLC SUEK-Khakassia are presented.
