The article discusses and substantiates the relationship of technical characteristics, namely, the load capacity of dump trucks, where a regular increase in the depth of the quarry and the volume of rock mass can be traced. At the same time, the dependence of the volume of the rock mass on the load capacity of the dump truck is close to linear, which means that with an increase in volume by 1 t (1 m3), the change in its load capacity is constant. The main indicators in assessing the degree of use of dump trucks is the distance of transportation, taking into account the horizontal movement and lifting of rock mass from the quarry. According to the results of the established dependence of the operational speed, as well as the number of flights from the given distance, a reference performance of dump trucks is obtained, which serves to determine the performance of dump trucks To date, worldwide differences in technological transport schemes by operating enterprises will mainly continue to use existing modes of transport with the introduction of new transport systems on certain sections of the quarry, mainly on deep horizons, and secondly, more modern ones are used. In this regard, there is a need to carry out scientific research on modeling the operation of heavy-duty road transport taking into account its indicators, to study the influence of the parameters of a deep quarry on the choice of technological schemes for transporting rock mass, to develop effective ways of managing the working area. A number of scientific and practical works have been carried out in the Republic on the development of methods and means of adaptation of cyclic-flow technology, the formation of a transport system of deep quarries by technological modules when using a modular crushing and transshipment point, new technological schemes and parameters of cyclic-flow technology have been developed. The performance of dump trucks largely depends on the distance of transportation, the average daily duration of work and the utilization factor of calendar time. Indicators of technological road transport development include the average number of cars (by brand), the load capacity of the dump truck fleet and the average load capacity of one average dump truck. Each of these indicators is established by a simple summation of the corresponding shift, daily, monthly work results based on the existing accounting of the work of road transport. Correlation and regression analyses were used to process the data using the least squares method.
