Monitoring, Analyzing, and Modeling for Single Subsidence Basin in Coal Mining Areas Based on SAR Interferometry with L-Band Data

Excessive exploitation of underground mine resources has caused serious land subsidence in China. This paper focused on monitoring and modeling the single basin coal mining area based SAR interferometry (InSAR). The optimum InSAR processing strategy to monitor was built obtain with large deformation. And a method three-dimensional mathematical measurements presented. Using Jining Coalfield (China) as study area, we acquired 7 L-band PALSAR images from January 2008 February 2010 Coalfield. deformation maps different periods were obtained. Taking Geting Coal Mine within coalfield an example, finely analyzed interpreted maps. Compared simultaneous filed measurements, precision measurement using D-InSAR analyzed. root mean square error 1.37 cm. fine interpretation analysis for established. experiments have proved that technique data is suitable 3D could be used area.
