“…Figures 2 and 3 shows graphs relating hoisting and thrusting velocities to the height of excavation while the bucket is moved within the work area of an excavator following equidistant paths -initial, intermediate or terminate. Calculated velocities of hoisting and thrusting were determined with the help of a computing experiment run for the EKG-20A excavator made by JSC «Uralmashplant» [11][12][13]. The data obtained leads to the conclusion that the velocities of working motions depend both on the height of excavation and the type of motion path for the bucket (its cuttingedge top).…”

It is shown that controlling excavation of rock mass using an open-pit excavator with a front shovel as its operational equipment is quite a difficult task due to the complexity of control under almost nonstop adjustment of velocities of working motions (hoisting and thrusting). It was established that operation parameters of the main mechanisms depend on the type of path of motion and position of the bucket in the excavator’s work area. The process of excavation was algorithmically described, and kinematic transfer functions for the operational equipment mechanism were determined, characterizing correlations between the velocity of excavation and the velocities of working motions.
