The article considers methods for calculating the stability of slopes that allow us to quantify the impact of various factors on the state of the rock mass. A generalized classification for slope stability calculation methods is provided. The considered method allows us to take into account the coefficient of structural weakening, that is, the fracturing of rocks. Entering the appropriate coefficients ensures sufficient accuracy of calculations of the stability of the sides of the quarry, especially at large depths. In this work, in addition to calculations based on computer programs, calculations were made using the VNIMI method. The article discusses methods for calculating the stability of slopes that allow us to quantify the impact of various factors on the state of the rock mass. A generalized classification for the slope stability calculation method is given. The considered method allows us to take into account the coefficient of structural weakening, that is, the fracturing of rocks. Entering the appropriate coefficients ensures sufficient accuracy of calculations of the stability of the quarry sides, especially at great depths. In this work, based on the VNIMI methodology, the software of the USTOI computer software complex was calculated, and the corresponding coefficient of stability margin was obtained. These methods of engineering calculations are based on the method of algebraic summation of forces on curved sliding surfaces and the method of polygon forces. Calculations of the formula for various forms of a uniform slope collapse prism are considered. The geometry and load of elements in various forms of the prism are obtained.
