Coal is an important energy and has played an important role in the development of national economy.In order to reduce the negative impact of ground subsidence after coal mining,it is necessary to monitor the ground and study the law of ground subsidence.Synthetic aperture radar interferometry technology has the characteristics of whole-time monitoring,imaging is not affected by climate,wide monitoring range and so on,which has obvious advantages compared with traditional monitoring methods.Based on 15 Sentinel-1A image data,small baseline subset method(SBAS)was adopted to conduct multi-temporal monitoring of Shengli No.1 open-pit coal mine,and the distribution and varia-tion trend of land subsidence area in the mining area from October 2022 to March 2023 were obtained.And the results of the SBAS monitoring are verified by field investigation,which proves the reliability of the SBAS technology applied to the monitoring of land subsidence in mining areas.
