摘　　要：为消除白云鄂博铁矿主、东采场边坡发生岩块掉落和滑坡的安全隐患,提高边坡稳定性,对白云鄂博铁矿主、东采场边坡区段进行稳定性分析。针对主采场、东采场存在危岩掉落或边坡滑落的区段,采取全长粘结锚杆+坡面挂网喷砼+泄水孔、泄水孔排水以及预应力锚索+钢筋混凝土挡墙+肋柱+泄水孔和预应力锚索+格构梁+挂网喷浆+泄水孔等边坡治理方式对其进行加固,并建立人工监测、全站仪监测和边坡雷达、裂缝计、全球导航卫星系统(GNSS)接收机等边坡监测系统以及相应的安全管理体系,确保边坡的稳定,保证矿山的安全生产。In order to eliminate the hidden dangers of rock falling and slope slide on slopes in Main Stope and East Stope of Bayan Obo Iron Mine as well as improve slope stability,the stability analysis of the slopes in Main Stope and East Stope of Bayan Obo Iron Mine is carried out.Such modes of slope treatment as full-length grouted bolt+shotcrete with wire mesh on slope surface+drainage opening,drainage with drainage opening and pre-stressed anchor cable+reinforced concrete retaining wall+rib column+drainage opening and pre-stressed anchor cable+half lattice girder+shotcrete with wire mesh+drainage opening are taken to reinforce the sectors with rock falling or slope slide in Main Stope and East Stope of Bayan Obo Iron Mine.Moreover,such slope monitoring systems as artificial monitoring,total station monitoring,slope radar,fracture meter and global navigation satellite systems(GNSS)receiver as well as corresponding safety management system are established to ensure the slope stability and safe productions of the mine.
