摘　　要：利用常规地面监测与地下多点位移计监测相结合的立体监测方式,对山西省万家寨引黄工程北干线1号隧洞下伏崔家岭煤矿采空区不同埋深不同部位的岩移变形进行了监测。并利用不同方法对监测资料进行了比较分析,有效地消除了温度变化的影响,客观地反映了采空区上覆岩层的真实变化规律,为采空区处理设计提供了可靠的技术依据,也为工程的安全运行提供了技术保障。The combination of traditional ground monitoring and underground multi-point displacement gage monitoring system is used for rock displacement deformation monitoring overlaid on Cuijialing coal mine goaf which locates under the No. 1 water diversion tunnel of North Main Route of Wanjiazhai Yellow River Diversion Project. The monitoring results are compared with initial data by different methods and the measurement data is treated to eliminate the influences of temperature change. The deformation of rock can be objectively reflected and provides a reliable technical basis to design the treatment measures and the safe operation of the Project.
