At present, the mining area often uses the method of establishing surface movement observation station and regional surveying and mapping to monitor the collapse range in the mining area and investigate land use. With the progress of remote sensing technology, Huainan mining area carries out the Interferometric Synthetic Aperture Radar (InSAR) and TM image technology research for the mining subsidence area to obtain land use characteristics and provide the technical basis for the land analysis and land reclamation in Huainan mining area. This paper mainly studies the extraction method of land use information of Dingji mining area and Guqiao mining area in Huainan, on this basis, it analyzes the information of land use and land cover change from 2015 to 2005, and extracts land use information of the mine area.%目前各矿常采用建立地表移动观测站及区域测绘地形的方法，对矿区的塌陷范围进行监测，实地调查土地利用情况。随着遥感技术的进步，淮南矿区对采煤塌陷区域进行了基于合成孔径雷达干涉（InSAR）、TM影像技术研究，获取地表土地利用特征，为淮南矿区土地分析与复垦提供技术依据。论文主要研究淮南丁集、顾桥矿区土地利用信息的提取方法，在此基础上分析2005年~2015年土地利用/土地覆盖变化信息，提取矿区土地利用信息。
