为了探究山西省阳城地区煤矿采空区影响范围和地表历史形变过程,为工程建设提供避让依据,采用SBAS-InSAR技术对该地区2019年1月至2020年7月间的地表形变进行监测,分析地表沉陷的原因,利用同期水准监测结果验证了InSAR结果的可靠性。结果表明,SBAS-InSAR技术能及时监测到黄土地区采空沉陷区的动态变化过程,开采深度、停采时间和掘进位置是影响该地区地表沉陷变化的主要原因。
Abstract:In order to explore the influence range of goaf and the historical deformation process of historical surface deformation processes in the Yangcheng Area of Shanxi Province, and provide a basis for engineering construction, we used the SBAS-InSAR technology to monitor the surface deformation of this area from January 2019 to June 2020, analyzed the possible causes of surface subsidence, and verified the reliability of InSAR results by using the monitoring results of the same period. The results show that the SBAS-InSAR technology can timely monitor the dynamic change process of subsidence area in the loess area. The mining depth, stop time and excavation location are the main reasons that affect the subsidence changes in the area.
