Abstract: The justification of the design parameters of the cargo platform of a dump truck depends on various factors, among which is the transported rock mass. The purpose of this study is to determine the parameters of the bulk material model loam and clay for the simulation of loading and unloading processes of a 220-ton dump truck cargo platform using the discrete element method. The analysis of the parameters of loam and clay as a loose medium is carried out. The parameters of the model of loamy and clay bulk media for simulation by the method of discrete elements are determined. The results of a study on determining the parameters of the loam and clay model depending on rolling resistance and bulk density are presented. The validation of the obtained results of the simulation of loam and clay was carried out by comparing the slope angle of the obtained models and the real geometry of the loam-clay cap.
