Research on Displacement Monitoring Technique for Goaf along Power Transmission Line Based on GF-3 Satellite Data

In this paper, two typical demonstration areas were selected in Shanxi Province for deformation monitoring of geological disasters likely to happen to the characteristic power passageways in Shanxi demonstration area with domestic GF-3 SAR satellite data and interferometric SAR technique. A total of fifty-three goafs were found, among which seventeen were in a large size and a few just lie in the zone of the power transmission line. One of the goafs was detailed herein. Ultimately, the feasibility and the application value of GF-3 satellite and microwave remote sensing technique in the field of deformation monitoring of geological disasters in power passageways were verified with the aim of promoting technological advancement in power monitoring, providing new technical means for the safe operation of power infrastructures, improving monitoring efficiency, and lowering monitoring costs.
