摘　　要：某铜矿井下破碎硐室上部原有溜井发生破坏,治理后在对称方向新施工一条主溜井与已有原矿仓贯通。新溜井投入使用后发现破碎硐室顶板及侧墙出现多处裂缝、露筋和渗水等现象,通过现场调查和FLAC3D数值模拟分析,确定了加固处理方案和渗水处理方案,达到了安全治理的效果。本文对具体的加固方案进行了详细介绍,提出紧邻已有工程爆破施工前的预防工作。The original pass in the upper part of the broken chamber of a copper mine was damaged,after treatment,a new main pass was constructed in the symmetrical direction to connect with the existing raw ore bin.After the new pass was put into use,it was found that there were many cracks,exposed bars and water seepage in the roof and side wall of the crushing chamber,through the field investigation and FLAC3 D numerical simulation analysis,the reinforcement treatment scheme and water seepage treatment scheme were determined,achieving the effect of safety treatment.In this paper,the concrete reinforcement scheme is introduced in detail,and the prevention work before blasting construction is proposed.
