Monitoring mine collapse by D-InSAR

Abstract For harmful ground collapse and its special deformation characteristics, which causes SAR images to lose coherence, InSAR technology cannot be applied in monitoring surface collapse in mining areas. We took the Shenmu mining area in northern Shaanxi province as an example to study subsidence in mining areas and proposed an interpolated multi-view processing method. The results show that this method can improve the detectable deformation gradient to a certain extent and can become a good reference value for monitoring large scale gradient deformation. We also analyzed the rules for temporal decorrelation in mining.
