• It is shown that in the process of rock excavation, the joint action of the main actuating mechanisms (lifting and thrusting mechanisms) of an open-pit excavator with the operational equipment of a front shovel type forms a leverage mechanism connecting the main mechanisms of the excavator and its bucket and transforming their operating parameters into parameters of energy and force realized on the cutting edge of a bucket (its teeth) in accord with properties of the mechanism kinematics. As a result of the analysis of kinematics and forces of the leverage, expressions were obtained for kinematic transfer functions of that mechanism, which define relations between the velocity of bucket’s cutting edge (excavation velocity) and velocities of operating motions (lifting and thrusting) in the case of the bucket moving within the working area of the excavator. An optimization algorithm to control the operation of an open-pit excavator was developed, which allows obtaining desired values of the operating parameters of its main mechanisms when they are utilized in the process of excavation on an excavated face.
