The study compares classical and modern approaches to calculating the stability of quarry slopes and walls. It considers the methods of Fellenius, Bishop, Janbu, and Spencer, implemented in the Slide 2D (Rocscience) and «Stability of Quarry Slopes» software packages (NJSC company «Abylkas Saginov Karaganda Technical University» Using the Syrymbett deposit as an example, numerical modeling of the stress-strain state of slopes was performed while varying the angles of inclination, lithological composition, and strength properties of the rock mass. Patterns in the change in the stability factor FoS depending on the structural and physical characteristics of the rock were identified. The calculation results showed the proximity of analytical and numerical solutions, which confirms the correctness of the selected models. The conclusions and recommendations obtained can be applied in the engineering design of stable quarry side profiles and in the prediction of deformation processes.
