Abstract: The relevance of using modern software packages to justify the stability of open-pit slopes is driven by the need to improve safety, forecast accuracy, and the efficiency of mining operations. Despite this, many engineers do not consider such solutions mandatory, which is due to several factors. First, regulatory documents do not always require complex geomechanical calculations using numerical methods. Second, existing software packages are often highly complex and narrowly specialized, which limits their adoption. These factors result in the insufficient dissemination of more precise technologies for predicting rock mass behavior, which could significantly enhance control over the stability of pit slopes. The objective of this study is to explore the capabilities of modern software packages for more accurate justification of slope stability, demonstrated through the example of the Gorevsky lead-zinc deposit. The article examines the main reasons limiting the adoption of advanced mathematical methods in slope stability forecasting practice and analyzes various software solutions that allow for the consideration of lithological differences, rock mass heterogeneity, and the calculation of stability safety factors. Modeling and calculations of stable slope parameters were performed using various software packages. The study's results show that using modern software solutions significantly improves the accuracy of stability calculations, enhances the detail of rock mass models, and improves forecasting. This, in turn, increases mining safety, reduces risks, and enhances the economic efficiency of mining operations, highlighting the necessity of their widespread adoption in engineering practice.
