Abstract: To improve the reliability of equipment, it is necessary to study the processes of its operation. The study of the operation of mining dump trucks in the conditions of quarry roads makes it possible to simulate the operational reliability of the components of the power structure of the bearing system and the chassis suspension guide. The obtained results of studying the processes of CS operation are the initial data for modeling. To study the operation of loading modes, statistical studies were conducted on the indications of the BelAZ 7530 dynamic weighing system over the past six months (relevance for February 2024) at one of the Kuzbass sections. The purpose of the work is to analyze the readings of the dynamic weighing system during the operation of mining dump trucks with a load capacity of 220 tons. According to the results of the study of the operation process of "carbon carriers" and "rock carriers" based on the BelAZ 7530 model in the conditions of operation at the Kuzbass section, the following were made: the mass of cargo transported on a "carbon carrier" is always greater than on a "rock carrier" due to the different volume of cargo platforms, density and fraction of cargo transported (the average weight of cargo transported for "the cargo carrier" is 175.0 [t], and for the "carbon carrier" 200.4 [t]); for six months there was a regime where the loading factor of the cargo platform on the "carbon carrier" was 1.18 or 260 [t]; statistics on the asymmetry of fully loaded "carbon carriers" and "steam locomotives" over the last six months of operation have shown that dump trucks with a probability of 56.4% are overloaded to port from cycle to cycle.
