Abstract: For the problem that DInSAR technique is easily influenced by loss related of time and space and atmosphere phase delay, Small Baseline Subset Approach (SBAS) method is applied to process 9 pairs of ALOS PALSAR data. The accumulated mine subsidence in village area from 2007 to 2011 were obtained. The results show that the maximum subsidence in the area is more than 800 mm during this period. SBAS processing results have high correlation (0.98) with levelling results when the subsidence is less than 600 mm, and the max difference is 19.8 mm. According to the temple subsidence analysis of measuring points, it is reliable to use SBAS technique to monitor the area of moving basin boundary and the critical slope of buildings.
