Abstract
The article contains the research results for a rational mining mode, definitions, and averaging of the operating stripping ratio. When determining the mining mode using open-pit hydraulic excavators, the problem appears with averaging the operating stripping ratio. Averaging is usually achieved by changing the pit wall angle at the expense of the respective change in the bench width. Minimum bench width serves as a limiting factor if working benches have to be reduced during the open pit mining. Continuous mining operations in an open pit require calculation and averaging the operational stripping ratio. There is a classical approach to calculate the average operational stripping ratio, but this method is graphical and has some errors. Therefore, a mathematical simulation was carried out based on integral calculus to obtain more precise values.
