在煤矿开采过程中，由于表土含水层的失水，引起地层的沉降，导致煤矿立井井壁破裂，严重威胁煤矿生产安全，造成了巨大的损失。为采集地层移动变形（水平移动和垂直移动）的监测数据，并利用所得数据进行整理分析，最终查明地层沉降的位置及三维位移规律，进行地层沉降的长期? During the process of coal mining, due to the loss of water from the aquifer in the topsoil, the settlement of the formation caused the rupture of the shaft wall of the coal mine and seriously threatened the safety of coal mine production, resulting in huge losses. In order to collect the monitoring data of deformation (horizontal movement and vertical movement) of formation and use the data to conduct the consolidation and analysis, finally find out the position of sedimentation and the three-dimensional displacement rule,
