摘　　要：淋水巷道稳定性及有效治理对于矿山地下掘进具有重要的意义。以非洲某铜钴矿为研究背景,分析了矿区水文地质情况与围岩稳定性,分析了巷道帮壁淋水原因和稳定性,给出了巷道帮壁淋水治理措施。结果表明:受区域地质影响,巷道淋水来源于构造承压水、区域性淋水及地质钻孔涌水;巷道帮壁淋水采用注浆加固能有效治理,通过对注浆压力的变化情况进行量化分析,并将注浆划分为微压—扩散—加固—劈裂4个阶段,得出了各阶段注浆孔围岩、浆液变化特征,对现场注浆施工具有重要的指导意义。The stability of drenching roadway and its effective treatment are of great significance for underground excavation of mines.Taking a copper-cobalt mine in Africa as the research background,this paper analyzes the hydrogeological conditions and surrounding rock stability of the mining area,analyzes the causes and stability of the water spray on the side wall of the roadway,and gives the treatment measures for the water spray on the side wall of the roadway.The results show that due to the influence of regional geol ogy,the roadway watering comes from tectonic confined water,regional watering and geological borehole watering.Grouting reinforcement can effectively control the water spray on the sidewall of roadway.Through the quantitative analysis of the change of grouting pressure,the grouting is divided into four stages:micro�pressure-diffusion-reinforcement-splitting.The variation characteristics of surrounding rock and slurry of grouting holes in each stage are obtained,which has important guiding significance for on-site grouting con struction.
