Abstract: Determining the utilization factor of a mining dump truck, taking into account the characteristics of the rock mass and loading, is one of the urgent tasks of modern mining production. The purpose of this study is to study the effect of the process of loading loam and clay into a dump body on the utilization factor of a 220-ton mining dump truck. The parameters of mining equipment and the scheme of loading loam and clay into the dump body of a 220-ton dump truck are analyzed. Models of mining equipment and a simulation model of the process of loading loam and clay into the cargo platform of a dump truck have been developed. Simulation modeling by the method of discrete elements of the process of loading loam and clay into the cargo platform of a dump truck was carried out and the values of the weight of the cargo were obtained both by a single bucket and in the cargo platform as a whole. The validation of the obtained results of simulation modeling of the loam and clay loading process was carried out by comparing the obtained models and the actual geometry of the loam-clay cap in the cargo platform of the Belaz 7530 dump truck. The dependences of the weight of the cargo in the cargo platform of the Belaz 7530 dump truck on the number of buckets when loading with Komatsu PC 2000 and EKG-35 excavators are presented. The influence of the loam and clay loading process in the GP on the utilization factor of the dump truck load capacity has been revealed.
