白马铁矿Ⅱ号排土场边坡稳定性分析及病害防治探讨

Stability Analysis of the Current Slope of No.Ⅱ Dump Site of Baima Iron Mine and Discussion on Disease Prevention

白马铁矿Ⅱ号排土场等级为二级,属矿山和周边设施的重大危险源,排土场失稳、滑坡和泥石流灾害发生,将严重威胁到矿山的安全生产。因此,定期对排土场边坡稳定性进行分析,有利于规避相应的灾害风险,确保排土场整体安全性。本文采用极限平衡法、强度折减法对排土场现状边坡进行稳定性分析,并提出排土场边坡病害防治措施。

Baima Iron Mine No.Ⅱ dumping site is grade Ⅱ,which is a major danger source for the mine and sur⁃rounding facilities.Unstable dumping sites,landslides and debris flow disasters will seriously threaten the mine's safe production.Therefore,regular analysis of dump slope stability is conducive to avoid the corresponding disaster risk and ensure the overall safety of waste dump.In this paper,the limit equilibrium method and the strength reduc⁃tion method were used to conduct stability analysis on the current slope of the dump,and the prevention and treat⁃ment measures of the slope in the dump were proposed.
