Abstract: Determination of the load capacity utilization factor of the dump truck, taking into account the physical and mechanical properties of the rock mass and loading parameters, is one of the urgent tasks of modern mining production. The purpose of this study is to investigate the influence of the sequence of overburden loading into the loading platform on the capacity utilization factor of the dump truck BelAZ-75310. The parameters of the mining and loading equipment and overburden loading schemes into the cargo platform of the 240 t dump truck are analyzed. The simulation model of the process of overburden loading into the cargo platform of the dump truck was developed, simulation modeling was carried out and the values of cargo weight in a single bucket and in the cargo platform as a whole were obtained. Validation of the obtained results of simulation modeling of the overburden loading process by comparing the obtained models and the actual geometry of the cap in the cargo platform of the dump truck BelAZ-75310 is carried out. Dependences of cargo weight in the cargo platform of the dump truck BelAZ-75310 on the number of buckets at loading by excavators Komatsu PC 2000 and EKG-35 are presented. The influence of the sequence of overburden loading into the load platform on the utilization factor of the dump truck capacity is revealed.
