摘　　要：结合江西乐平市月形铜多金属矿帷幕注浆堵水工程,主要阐述了矿山发生涌水灾害后治理的方法选择及治理工序,并对注浆法的施工工艺加以研究和推广,同时简单介绍了施工过程中一些常见问题及处理对策。根据该工程的工程地质条件、工程性质、预算等限制条件选择高压孔内循环式注浆;下行式分段注浆方式方法。浆材为水泥粉煤灰和水泥粘土浆两种,必要时加入适量水玻璃。最后,通过钻心、压水对比和面波检测确定注浆是否达到工程要求。According to the engineering of curtain grouting for water control in Yuexing copper polymetallic deposit of Jiangxi, the paper described the selection of treatment methods and the treatment process, the grouting construction technology was studied and promoted; briefly introduced some common problems in construction process with countermeasures. Based on the restricting conditions such as engineering geological conditions, engineering properties and the budget, high-pressure hole with internal circulation grouting and downward stage grouting were selected. The grouting material were cement fly-ash and cement clay grout, water glass grout could be added while necessary. The engineering quality was determined by drilling coring, water pressure test and surface wave detection.
