Abstract

It was established that during the process of excavation realized by an open-pit excavator, the joint action of drives powering its main (hoisting and thrusting) mechanisms changes the levels of power consumed both by those drives individually and by the power unit as a whole. A computing experiment was used as the research method. It was run for the EKG-20A excavator made by JSC “Uralmashplant” and on the basis of a simulation model for the process of excavation realized by the front-shovel operational equipment. Main factors were determined which could define how the power consumed is distributed between the drives of the main mechanisms. A method was proposed to calculate the power characteristics of an open-pit excavator working up the excavation face in specified mining and operating conditions on the basis of the simulation model. Estimating the power characteristic would allow one to determine a rational scheme of excavation works.
