Abstract: Justification of the design parameters of the load platform of the quarry dump truck depends on various factors, among which the main ones are the properties of the transported rock mass (overburden - sandstones, mudstones, siltstones). The purpose of this study is to determine the parameters of the model of bulk material - overburden rock - for simulation modeling of the loading and unloading processes of the cargo platform of a 240-ton quarry dump truck using the discrete element method. The parameters of overburden rock as a bulk medium are analyzed. The parameters of the model of sandstone-siltstone-mudstone bulk medium for simulation modeling by the method of discrete elements are determined. The results of the study on determination of overburden model parameters depending on the rolling resistance coefficient and bulk density are presented. Validation of the obtained results is carried out by comparing the slope angle of the obtained models and the real geometry of the sandstone-siltstone-mudstone cap.
