摘　　要：高强度的煤矿开采与利用给矿区地表、地质结构和周围环境造成破坏。采用InSAR和GNSS技术相结合的综合方法,可以对矿区地表形变及其周围的基础设施进行广泛、持续、高精度的监测。文中针对采空区电线塔的安全监测,提出一种InSAR形变辅助的电线塔倾斜监测方法,根据先验InSAR形变获取电线塔周围沉降所在坡面的坡向,并布设2个GNSS测站,从而有效地监测电线塔倾斜。本研究以我国山西省某采空区为例,利用SBAS-InSAR技术获取了2019-06-08—2023-06-11共4年的形变数据。针对已发生沉降的三座电线塔采用文中提出的方法布设6个GNSS测站,成功监测因采空区形变造成的电线塔的倾斜状态,文中方法为电线塔的安全运行与维护提供参考。High-intensity coal mining and utilization have caused substantial damage to the surface,geological structure,and the immediate environment surrounding mining areas.The comprehensive method combining InSAR and GNSS technology can be used to monitor the surface deformation and the surrounding infrastructure extensively,continuously and with high precision.In this paper,we propose an InSAR deformation-assisted tilt monitoring method specifically designed for the safety surveillance of power line towers within mining regions.Based on the preliminary InSAR deformation data,the slope direction of the area where the tower's settlement is located is identified,and subsequently,two GNSS stations are strategically deployed in alignment with this slope direction to achieve effective tilt monitoring of the power line towers.To demonstrate the efficacy of our method,we take a mining area in Shanxi Province,China,as a case study.The study obtained the deformation results for a total of 4 years from June 8,2019 to June 11,2023 using SBAS-InSAR technology for an example of a mining area in Shanxi Province,China.For the three towers situated within the subsidence basin,six GNSS stations were deployed according to our proposed method.The tilt of these towers,resulting from the deformation of the extraction zone,was successfully monitored,thereby offering valuable decision support for ensuring the safe operation and maintenance of the towers.
