Improving the Efficiency of Using Hydraulic Reverse Shovel Excavators on Inclined and Steeply Dipping Fields by Controlling the Overburden Rate

Abstract

The economic efficiency of open-pit mining is largely determined by the choice of a rational mining regime, which is associated with the problem of averaging the operational overburden rate over periods. At the same time, the authors do not always give recommendations when averaging the operational rates of overburden and the implementation of the selected mode of open-pit mining in practice, most often associated with determining the changing width of the working site throughout its entire existence. The article describes a method for controlling the operational overburden rate when using hydraulic reverse shovel excavators using elements of mathematical modeling of averaging the operational overburden rate, which provides high accuracy of the results and eliminates the influence of the human factor on their calculation.
