Outline
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.
