司家营铁矿采场西帮边坡治理方案

Treatment Scheme of the West Slope of Sijiaying Iron Mine Stope

为确保司家营铁矿正常生产和人员设备安全,应用Geo-slope软件,对该矿一期采场西帮N#14~N#16线特厚冲积层边坡滑坡进行了反演分析,采用圆弧滑动法进行了验算,得到了边坡土体的力学参数。通过对边坡进行稳定性分析评价,制定了削坡和坡脚土钉加固的2种边坡治理方案,经对比分析,认为土钉施工稳定边坡岩体方案不影响坑底最终境界位置,避免高压线塔和电线杆的移设,有助于确保该矿西帮边坡的稳定。

In order to ensure the mine normal production and the safety of equipment and person-nel,the thickness alluvium slope landslide of N#14 ~N#16 line of the west slope of the first stope of Sijiaying iron mine conducted inversion analysis based on Geo-slope software,the checking calculation is conducted by adopting the circular sliding method to obtain the mechanical parameters of slope soil.Through the e-valuation of slope stability analysis,the two slope treatment schemes are proposed that are the cutting slope and slope toe soil nail reinforcement.The comparison and analysis results show that,the final bot-tom boundary position can not be impacted by the scheme of the soil nail construction to stable the slope rock mass,it also good for avoiding moving the high-pressure pylons and telegraph poles and ensuring the stability of the mine west slope.
