摘要
为了对露天矿山边坡失稳事故风险进行科学合理的定量定性评价,在分析和归纳影响露天矿山边坡失稳因素的基础上,根据事故树构造原理建立了露天矿山边坡失稳的事故树模型。通过计算事故树的最小割集、最小径集、结构重要度,得出影响露天矿山边坡失稳的关键因素:弱面存在、区域地质构造复杂、地下水作用、违规开采、管理与制度建设等,并据此提出针对性防治措施,对防治露天边坡失稳具有重要的指导意义。
In order to obtain the scientific, resonable, quantitative and qualitative evaluation results of the accident risk of the open pit mine slope, according to the accident tree structure theroy, fault tree model of the open pit mine slope is established at the base of analyzing and summarizing instability factors of the open pit mine slope. The key factors that affect the open pit mine slope instability include that weak plane exists, the complicated regional geological structure, groundwater effection, illegal mining, manage- ment and institution construction are obtained by the calcuation of minimal cut sets, minimal path sets and the importance of structure. In line with the research results, some corresponding prevention measures are put forward. It have great important guiding significance for preventing and controlling of the open pit slope instability.
