Abstract
In this paper, a mining face of Tingnan mining subsidence basin in Shanxi Province was selected as experimental area. This article attempted to conduct the dynamic monitoring research to coal mining subsidence in western mining areas by use the method of combing D-InSAR and GPS technology. The observation points were installed on the main section and the three-dimensional coordinates of the points were measured by use the method of dynamic differential GPS. Meanwhile, the radar images of this subsidence area were processed by use the method of interferometry with daris software and interferogram of subsidence area was obtained. Through this study, the GPS monitoring data and the InSAR deformation data were integrated and the dynamic subsidence contours of experimental area were obtained. GPS/InSAR fusion technology provides a new technological mean to large-scale dynamic monitoring of coal mining subsidence in western mountainous mining areas and shows good applying prospect in coal mining subsidence monitoring and disaster warning.
