Abstract:To comprehensively evaluate the stability of open-pit mine slopes during the production process, an analytical model is established based on the Analytic Hierarchy Process and fuzzy mathematics theory to evaluate the stability of slopes. Fully consider the engineering geology, geometric conditions, hydrology and meteorology, and external loads that affect the stability of open-pit mine slopes, and establish a two-level evaluation index system consisting of 14 sub indicators. Based on the trend characteristics of the impact of different sub indicators on the stability of open-pit mine slopes, establish a membership fuzzy matrix and weight set for the corresponding indicators; Construct a fuzzy comprehensive evaluation system based on two-level analytic hierarchy process and evaluate the stability of open-pit mine slopes. Research has shown that the stability evaluation method for open-pit mine slopes based on Analytic Hierarchy Process and Fuzzy Mathematics theory is simple and practical in calculation, and the evaluation results are in good agreement with the actual situation. It can provide guidance and assistance for the stability evaluation of open-pit mine slopes.
