Mining Damage Analysis of 93 Upper 10 Working Face in Nantun Coal Mine Based on DInSAR

In order to study the application of DInSAR in monitoring coal mining subsidence deformation and analyze the dynamic damage degree of high grade road, the SAR image differential interference experiment in 93 upper 10 working face of Nantun Mine is done. Two-pass differential method is adopted in obtaining dynamic subsidence value, and drawing subsidence sinking contour and profile of the maximum subsidence, getting the dynamic subsidence range and sinking degree of the surface above 93 upper 10 working face. On this basis，the analysis of Zouji highway damage is done.
