Abstract: Fushun,one of the most famous coal mining cities in China,is located in Fushun Basin,Liaoning Province.Fushun coal field which started its industrial products in 1901 is mainly concentrated in the basin.Geomorphological changes have appeared in Fushun area due to over 100-year's coal mining.West Open Coal Mine is a famous man-made hole in Asia due to long time open mining.A large subsidence region has appeared in eastern Fushun area due to long time underground mining.Meanwhile,three man-made hills have been piled up by mass of waste rocks produced from coal mining activities.In recent years,geomorphological changes are still going on with open and underground coal mining.Satellite remote sensing technology can provide continuous spatial and temporal data to monitor this kind of geomorphological changes effectively.In this study,multi-temporal and multi-source satellite remote sensing data were used to monitor the geomorphological changes associated with coal mining activities in Fushun area.Three-dimentional perspective imagery generated from ASTER data clearly shows the geomorphological characteristics of the West Open Coal Mine,the subsidence region,and three waste rock piling fields.Multi-temporal Landsat MSS,TM,ETM+and ASTER remote sensing images reveal that the water flooding area was enlarged by 1.73km2 during the 2001～2006 period due to the development of surface subsidence.Multi-temporal ASTER DEM images also indicate that the mining depth of the West Open Coal Mine increased up to 55m in 2001～2006.Meanwhile,multi-temporal ASTER images showed that two new waste rock piling fields appeared in subsidence region,resulting in a maximum elevation increase of 25m in the same period.This study shows that surface geomorphological changes associated with coal mining can be quantitatively detected in a high accuracy using satellite remote sensing technology.
