Abstract: The article discusses software based on the discrete element method for simulating the interaction of a bulk medium with mining equipment. The advantages, disadvantages and technical capabilities of various software products are analyzed, including EDEM, Rocky DEM, ThreeParticle, LIGGGHTS and Yade. The functional capabilities, computing performance, as well as publication activity devoted to research on the interaction of bulk materials with a metal structure or a mining machine node, corresponding to the state rubricators of scientific and technical information 52.00.00 - mining and 55.33.00 – mining engineering, for the software products under consideration, are evaluated. Rocky DEM and EDEM software have built-in calculation algorithms and contact models for particle (Ab-T10, Tavares) and smoothed particle destruction (SPH). The results of simulation modeling, using the method of discrete elements, of the interaction of rock mass with the cargo platform (body) of a quarry dump truck with a load capacity of 220 tons in the Rocky DEM and EDEM software are presented. A comparative analysis of software products based on the discrete element method has shown that Rocky DEM is the optimal software for solving problems related to the simulation of the interaction of the bulk medium with the cargo platform (body) of a dump truck, and topics of scientific research in the field of mining machines.
