Abstract
Determining the utilization factor of a mining dump truck, taking into ac? count 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 coal loading process into a dump body on the utiliza? tion factor of a 220-ton mining dump truck. The parameters of mining equipment and schemes for loading coal into the dump body of a mining dump truck of 220 tons are analyzed. Models of mining equipment and a simulation model of the process of loading coal into the cargo platform of a dump truck have been developed. Simulation modeling by the method of discrete elements of the coal loading process into the cargo platform of a quarry 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 the simulation of the coal loading process was carried out by comparing the obtained models and the actual geometry of the coal cap in the dump body of the BelAZ 7530 dump truck. The dependences of the weight of the cargo in the dump body 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 coal loading process in the SOE on the utilization factor of the mining dump truck load capacity has been reve.
