Abstract
Effective management of slope stability risks is crucial for safe and cost-efficient operation of open-pit mines. Analytical methodologies have been developed to improve the handling of these risks. However, reducing slope angles to eliminate all potential instabilities is often not economically viable. Instead, a balanced approach that considers both safety and economic factors is necessary. Meticulous attention must be paid during the planning and production phases of open-pit mining operations. The primary objective is to maximize ore extraction while minimizing waste removal. Accurately determining bench heights, bench widths, and slope angles is of paramount importance. This study utilizes the multiple limit equilibrium method to analyze slope stability in a field characterized by the aforementioned parameters. The investigation confidently identifies the slip surfaces with the lowest safety coefficients among the potential slip scenarios. The outcomes are scrutinized using various calculation methodologies, including the Generalized Limit Equilibrium (GLE) and Bishop methods. To ensure a comprehensive evaluation and validation of the results, the analysis is conducted using the 'Plaxis 3D LE' software.
