摘要: 为实现露天煤矿绿色安全高效开采，截水帷幕作为1种节能降碳、保水采煤的新技术，不断应用到露天煤矿中。露天煤矿截水帷幕属于地下隐蔽工程建筑，其建造质量直接关系到截渗减排效果。以扎尼河、元宝山露天煤矿截水帷幕为例，归纳总结了截水帷幕效果检验方法，提出了声波透射法、取心验证法、抽（注）水试验法等7种效果检验方法，构建了应用于截水帷幕建造不同阶段、定性定量相结合的“七位一体”效果检验方法体系。“七位一体”效果检验方法体系可以全方位检验墙体浇筑完整性，获取墙体渗透系数，判断墙体渗漏范围，评价帷幕生态效应，为墙体渗漏修复提供参数依据，为评价截水帷幕的截渗效果提供技术支撑。Abstract: In order to realize green, safe and efficient mining in open-pit coal mines, water cut-off curtain as a new technology of energy saving, carbon reduction and water conservation, has been continuously applied to open-pit coal mines. The cut-off curtain of open-pit coal mine belongs to underground concealed engineering construction, and its construction quality is directly related to the effect of seepage interception and emission reduction. Taking Zhanihe and Yuanbaoshan open-pit coal mine water cut-off curtain as examples, this paper summarizes the test methods for the effect of water cut-off curtain, puts forward seven effect test methods, such as cross hole sonic logging method, coring verification method and pumping （ｉｎｊｅｃｔｉｏｎ） test method, and constructs an “seven in one” effect test method system applied to different stages of water cut-off curtain construction, which can comprehensively test the integrity of wall pouring and obtain the wall permeability coefficient, judge the leakage range of the wall, evaluate the ecological effect of the curtain, provide data support for the wall leakage repair, and provide technical parameters for evaluating the seepage interception effect of the water interception curtain.
