摘要
考虑到凹陷露天矿边坡的实际情况,以及在边坡稳定性评价时存在着模糊性和随机性,选取合适的评价方法对边坡的安全做出准确的判断,对于凹陷露天矿边坡的开采工作是非常有必要的。以北厂架崖山矿段露天矿边坡为例,根据采区露天边坡实际情况,以方位角为划分依据,将采区边坡划分为八个区域,建立影响边坡稳定性因素的15个指标的稳定性评级指标体系,基于AHP法确定各指标的权重,权重确定完成后,通过计算单指标联系度与综合联系度,确定北厂架崖山矿段边坡的安全等级。研究表明,区域Ⅵ、Ⅶ稳定性较差,建议采取相应的防治措施。
Considering the actual situation of the depression open-pit slope and the ambiguity and randomness in the slope stability evaluation,it is necessary to make an accurate judgment on the safety of the slope by selecting the appropriate evaluation method.In this paper,the open-pit slope of Beichang-jiayashan section was selected as an example.According to the actual situation of the open-pit slope in the mining area,the slope in the mining area was divided into eight regions based on the azimuth angle,and the stability rating index system of 15 indexes affecting the stability of the slope was established.The weight of each index was determined based on the AHP method,and then the safety grade of the open-pit slope of Beichang-jiayashan mine section was determined by the calculated single index connection degree and comprehensive connection degree.Studies have shown that the stability of regionsⅥandⅦis poor,and it is recommended to take corresponding preventive measures.
