Stability Analysis about Slope of Open Pit Mine Based on Fuzzy Synthetic Evaluation

Abstract:

Normal production of open-pit mine is directly affected by the safety of slope, especially in deep open-pit mine. According to the real conditions of Jinduicheng Molybdenum Open-pit Mine and considering slope stability influential factors such as rock properties and geological structures, slope geometry parameters, groundwater, blasting activities and others, a fuzzy synthetic evaluation model of slope stability is established, which involved membership functions and multi-level weight distribution method. The evaluation model was applied to the slope of Jinduicheng Molybdenum Open-pit Mine, and the results showed that the slope of the mine was general stable at present.
