中文摘要: 受不良工程地质条件、下部采矿活动及雨雪入渗等影响,曙光金铜矿露天边坡存在较为明显的蠕滑现象,导致多处台阶出现严重变形、开裂、下沉。通过边坡灾害体分析、边坡稳定性计算,并结合矿山实际情况,提出了5种边坡治理方案,分别为:①预应力长锚索+钢板方案;②喷锚网方案;③浆砌石挡墙+素喷方案;④预注浆固结方案;⑤微型桩+浆砌石挡墙方案。经多角度方案对比,最终选取了方案①与方案⑤相结合的综合治理方案。通过方案实施,取得了良好的边坡治理效果,保障了矿山安全生产,该矿山边坡治理的研究与分析可为类似条件软破岩质高陡边坡治理提供可借鉴的经验和依据。

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.
