This paper presents the results of numerical modeling of the stability of multi-tier waste dumps placed on the slopes of highland deposits. The main focus is on the influence of geometrical parameters—such as dump height, berm width between tiers, and slope angle—on the value of the safety factor. Calculations were carried out using the GeoStudio Slope/W software based on the Morgenstern-Price method. The parameter values were selected based on engineering and geological investigations typical for highland mining conditions. It was established that increasing the berm width between tiers leads to a higher safety factor due to stress redistribution and a reduction in shear deformations. It was also found that as the berm width increases, the dump slope angle decreases, resulting in improved overall stability. The obtained relationships can be applied in the design of waste dumps under mountainous conditions to enhance reliability and reduce technogenic risks.
