In this paper, it monitored ground subsidence in the coal mining area using two-pass D-InSAR technique. We obtained 9 ALOS PALSAR single-look complex (SLC) images in Yanzhou coal mining area from December 2007 to Februay 2009. Based on SAR interferometric pairs and SRTM DEM, we detected the subsided areas and got the vertical subsided quantity. We got the ground subsidence maps in different stages from 2007 to 2009. Several important subsided areas were selected and then analyzed in detail. It analyzed the general laws of mining subsidence. The results indicated that two-pass D-InSAR technique based on L-band PALSAR data and SRTM DEM is a very simple, rapid and efficient way to detect and to monitor ground subsidence in the coal mining area, even in the areas with vegetation covered.
