采空区稳定问题是南水北调中线工程一期总干渠的重大工程技术问题之一,为了掌握采空区变形情况,在焦作煤矿采空区开展了变形监测工作,监测项目包括水平位移、垂直位移等。通过对总干渠经过煤矿采空区的变形监测研究,为采空区的处理提供可靠的理论依据,对其它渠道设计可以起到借鉴的作用。 Gob area stability is one of the major engineering problems in the first phase of the Middle Route of South-to-North Water Diversion Project. In order to grasp the deformation of the goaf, deformation monitoring has been carried out in the gob area of ​​Jiaozuo Coal Mine. The monitoring items include horizontal displacement and vertical displacement . Through the monitoring of the deformation of the main canal through the coal mined-out area, it provides a reliable theoretical basis for the treatment of the goaf and can serve as a reference for other channel designs.
