Abstract:Affected by unfavorable engineering geological conditions, underground mining activities and rain and snow infiltration, there is obvious creep phenomenon in the open-pit slope of Shuguang Gold and Copper Mine, which leads to serious deformation, cracking and subsidence of many steps. Based on the analysis of slope disaster body and the calculation of slope stability, combined with the actual situation of the mine, five slope treatment schemes are put forward, namely: ① Prestressed long anchor cable + steel plate scheme; (2) Spray anchor net scheme; ③ Masonry retaining wall + plain spraying scheme; ④ Pre-grouting consolidation scheme; ⑤ Micro-pile + masonry retaining wall scheme. After comparing the schemes from different angles, the comprehensive treatment scheme combining scheme ① with scheme ⑤ was finally selected. Through the implementation of the scheme, good slope treatment effect has been achieved, which ensures the safe production of the mine. The research and analysis of slope treatment in this mine can provide reference experience and basis for the treatment of soft rock high and steep slopes under similar conditions.
