It is shown that operation parameters of the main mechanisms of an open-pit excavator (hoisting and thrusting velocities) vary within a wide range during the process of rock excavation. Based on the computing experiment aimed to calculate EKG-20A excavator parameters, hoisting and thrusting velocities were determined for a specified law of bucket motion (top of the cutting edge) within the work area of an excavator. Analytical dependencies were derived, which could be used to obtain required correlations between hoisting and thrusting velocities to move the bucket along equidistant paths at various inclination angles. Assuring agreement of operation parameters for the main mechanisms of open-pit excavators employed in rock excavation would allow one to increase the efficiency of their functioning. The results of the research could also serve as a basis for developing an adaptive system which would control the working process and enhance the performance of the excavator as a whole.
