摘　　要：在分析沈村、李沟矿水文地质条件基础上,提出利用天然岩体作为隔水幕墙、选址绕过采空区和在静水压力较高的深部巷道处加厚幕墙的设计思路,给出帷幕注浆截流施工的技术参数,建立了工程稳定性和质量优劣的评价指标。On the basis of an analysis of the hydrological conditions of Shencun coal mine and Ligou coal mine, the author of this paper proposes a designing idea that natural rock body is used as underground water blocking curtain to seal off underground water and the curtain should round the goal areas. In the deep part of the mine where the static water pressure is high, the separating curtain is to be thickened. The author also provides technical parameters of grouting for the water blocking curtain and also the technical appraisal criteria for the stability and quality of the curtain construction project.
