摘　　要：采用地下防渗墙方案对地下水补给通道进行帷幕截渗是露天煤矿防治水工作的新方法。从建墙条件、建墙技术和经济评价三方面分析了防渗墙的应用条件。以试验工程为例验证了常用建墙工艺的可行性,采用抽水试验检验了墙体防渗性能。A new method to solve the water control problem is cutting oil the seepage channel by curtain grouting, l~＇rom the construction conditions, construction technical and economic evaluation, the article analyzes the application conditions of diaphragm wall. Taking test engineering for example, the mine verifies the feasibility of construction technology, and adopts pumping to test the impervious performance of the wall.
