Abstract:n order to find out the development law of coal mining subsidence area in Feicheng city, by using astronautics remote sensing technology, dynamic change of coal mining subsidence area is surveyed. First, based on actual situation in investigation area, selected the datas of TM and SPOT-5 in 2006 in different times, relative images conduction has been carried out. On the basis of spectral characteristics of surface substance, correlation analysis is carried out, and the best band combinations are determined. By using ENVI software, information of subsidence area is automatically extracted by computer. Then three interpretation results (1996, 2002, 2006) of remote sensing are compared, and characteristics of changes in subsidence area are summarizd. The research result can provide decision support for sustainable development in mine area and can also provide the basis for geological disasters management.
