Abstract: The design process of mining dump trucks must be accompanied by modeling the operational reliability of the components of the power structure of the load-bearing system and the chassis suspension guide. Ensuring operational reliability is primarily determined by the presence of a mathematical description of representative conditions and operating modes of mining dump trucks on mining routes of sections, and secondarily by the tools, methods and load modeling techniques adapted to the initial data. The generalization of the results of the review of previously performed studies is reduced to the description of proposals for solving particular problems of the topic of operational reliability of quarry equipment and partially reflect the nature of the operating conditions of quarry dump trucks operating at Kuzbass coal mines. As a result of the work on the article, the authors identified typical cycles of operation of mining dump trucks with a load capacity of 220 tons. The processes of operation of "carbon carriers" and "rock carriers" based on the BelAZ 7530 dump truck model were selected as objects of research in the Kuzbass sections. The authors note that quarry dump trucks can be classified into dump trucks transporting minerals "carbohydrate" and dump trucks transporting overburden rock "rock carrier" after drilling and blasting operations. A typical cycle of operation of a "carbon carrier" is the transportation of coal from the face to a processing plant or coal warehouse. Typical operation cycle of a "rock carrier": transportation of large volumes of overburden after drilling and blasting operations to the dump. Of the total amount of rock transported by quarry dump trucks, the volume of overburden transported is 92%, and only 8% of dump trucks transport coal. Mining dump trucks with a load capacity of 220 tons are operated with different types of drives. The "carbon carrier", as a rule, is equipped with an asynchronous type of drive, and the "rock carrier" is synchronous
