Abstract: The article examines the study of high-speed modes of movement of a mining dump truck with a load capacity of 220 tons. The experimental results obtained at the Kuzbass section with the help of special equipment installed on a quarry dump truck with a load capacity of 220 tons are presented. The routes of movement of a quarry dump truck on the cut route and the distribution of speed modes of movement of a quarry dump truck with a load capacity of 220 tons in loaded and empty condition along the routes are studied. Two routes of movement of a dump truck in XYZ coordinates have been obtained. The height difference above sea level and the average travel time of the dump truck have been established. Statistical diagrams of the speed modes of movement of a quarry dump truck with a load capacity of 220 tons in loaded and empty condition along the routes are given. The results of measurements of the speed modes of movement of a dump truck show a large variation in the values of instantaneous speed at a fixed point in time and at a given point in space, due to the stochastic nature of the transport process under the influence of a large number of factors. The lowest speed of a dump truck along the entire route "Loading point - Unloading point" appears more often than the average and highest speeds, and reflects undesirable results for the productivity of the transport process. The lowest speed of movement of a dump truck indicates downtime for loading rock mass. High-speed modes of movement of dump trucks must be taken into account to optimize the operation of excavator-automobile complexes and when designing roads in quarries, which can lead to increased productivity and lower operating costs.
