ANALYSIS OF MINING GROUND DEFORMATION BASED ON THREE-PASS D-INSAR TECHNOLOGY

The DEM containing topographic information, enhanced differential interferograms, corresponding coherence and maps of mining ground deformation are extracted by processing six ENVISAT ASAR data covering a mine of Jining by three-pass D-InSAR.Then, mine ground subsidence is analyzed in the light of distribution of mining subsidence and statistics of subsidence area;finally, the accuracy analysis is executed by the way of comparing some level of monitoring result with the monitoring results from three-pass D-InSAR.The difference of the two monitoring results is shown, at the same time, main reason of it is discussed and analyzed preliminarily.The application of three-pass D-InSAR monitoring ground deformation of mining area is shown.
