The purpose of the paper is to increase the efficiency of the use of excavator equipment at the Yeristivsky openpit due to the introduction of information technologies. The following methods were used to solve the problems in the paper: analysis and synthesis of scientific sources of information for the study of the scientific foundations of the use of extraction and loading equipment, analysis of world experience in the effective use of extraction and loading equipment, analysis of the experience of the influence of automated mining transport control systems on extraction and loading equipment; methods of regression analysis, economic-mathematical modeling and technicaleconomic assessment. The scientific novelty of the research results lies in the establishment of factors that affect the productivity of the extraction and loading equipment. The practical significance lies in the possibility of using research results by mining enterprises and project organizations when planning mining operations. Thus, the paper compares the performance of the excavator equipment used in the conditions of the Yeristov open-pit, as a result of which it was established that the expected and actual performance have certain differences due to the indicator of the load cycle time. As a result of research, it was established that the cycle time at a turning angle of 20˚ to 30˚ will be minimal and will increase the productivity of the dragline. In addition, in specific mining and technical conditions, it was established that the implementation of the automated management system “WENCO” made it possible to increase the productivity of the mining transport complex and, in general, improve the technical and economic performance of the pit.
