Abstract: An urgent practical problem for a subsoil user is the decrease in the efficiency of a mining enterprise due to the natural growth of costs for excavation and transportation of rock mass, aggravated by the emergence of a discrepancy between the parameters of the excavator-automobile complex (EAC) and the mining and technical system of the quarry, changing and accumulating as mining operations develop. Formation of the EAC in conditions of increased competition in conjunction with the development of quarry space in order to eliminate their mutual discrepancy arising from changes in natural, mining, organizational and economic conditions during the development of steep deep-lying ore deposits is an urgent scientific task. The absence of a science-based tool for the subsoil user to evaluate and select mining and transport equipment at the stage of purchase and sale gives rise to less than effective management decisions on the formation of excavator-vehicle complexes in the conditions of high competition. This leads to a decrease in production efficiency due to an increase in maintenance and repair costs, a decrease in the service life of some units and equipment as a whole, an increase in maintenance and energy costs... The selection of equipment for the EAC should be based on a scientifically grounded methodology for determining the integral indicator of its consumer qualities, taking into account the technical perfection of the design of dump trucks and excavators, the efficiency of the service system throughout their service life, the degree of suitability for mining and technical conditions and the possibility of achieving high technical and economic indicators when working in a quarry or open pit. The purpose of this study is to improve the methodology for selecting mining and transport equipment when forming EACs in conditions of increased competition. The conducted research allowed to develop a methodological apparatus for express assessment and selection of mining and transport equipment when forming the EAC, as well as for comparison of equipment complexes as a whole
