Abstract
Justification of the design parameters of the dump body of a dump truck depends on various factors, among which is the transported mountain mass (coal). The purpose of this study is to determine the parameters of the bulk material (coal) model for the simulation of loading and unloading processes of a 220-ton dump truck mining truck tray by the discrete ele? ment method. The analysis of the parameters of coal as a loose medium is carried out. The parameters of the coal bulk medium model for simulation modeling by the method of discrete elements are determined. Studies are given to determine the parameters of the coal model depending on rolling resistance and bulk density. The validation of the obtained coal simulation results was carried out by comparing the slope angle of the obtained models and the real geometry of the coal cap.
