Abstract [en]
Ensuring the stability of pitwalls in open pit mining is a critical aspect of the safety of personnel, equipment, and the surrounding environment. Complex geological and geotechnical conditions encountered in practical open pit mining often present challenges in accurately assessing slope stability. This study employs both DIPS and Swedge software to enhance pitwall stability analysis. DIPS examines discontinuity orientations and distributions, providing essential geological insights,while Swedge simulates potential wedge failure modes, determines their sizes, and calculates factors of safety crucial for pitwall stability assessments. While both DIPS and Swedge have found individual or combined applications in numerous studies, a comprehensive and systematic evaluation of their performance across a spectrum of pitwall conditions, particularly in extreme weather environments, remains a major research subject. By combining the strengths of DIPS and Swedge, the study - not only refine our understanding of pitwall stability mechanisms but also developed a robust methodology applicable across diverse geological and climatic conditions. The results of this research contribute significantly to the body of knowledge in rock mechanics and open pit mining practices, offering practical guidance for enhancing pitwall stability in various operational contexts.
