摘　　要：大红山矿大理岩岩溶发育，由于突水造成井下大量涌水，同时引起地下水位急剧下降，引发了较大范围、较大规模的地面塌陷。通过进行幕址勘察、帷幕注浆设计及施工，并对帷幕注浆治水效果进行了评价，认为注浆帷幕堵水效果明显，帷幕注浆质量较好，可发挥显著的截流作用。Marble karst development in Da- hong-shah mine caused a great deal of water bursting in mine shaft, sharply lowering ground water and large scale of surface subsidence. Through the survey on the site of grouting curtain, design and construction of grouting curtain , and evaluating the effect about the grouting curtain from the various aspects of water management, it is found that the grouting curtain flow cut - off is very effective, the quality of grouting curtain is good, and the grouting curtain can play a significant role in the catcbwater work.
