Abstract:: Coal mining subsidence always causes environmental deterioration and surface subsidence, which restricts the rapid development of cities nearby. We took coal mining subsidence area of Xinjiang Weihuliang as the research area to extract the subsidence area information by using the high resolution remote sensing images in 2002, 2006, 2009 and 2013. By using the method of spatial pattern and dynamic degree to monitor the information of the subsidence area dynamically, we compared and analyzed the evolution trend and the characteristics of temporal and spatial variation of the subsidence area. The result showed that the subsidence area had an eastward trend and the events of geological hazards had been increasing. In particular, the growth of geological hazards was the fastest in the period from 2006 to 2009. Meanwhile, the area of backfillings increased to 92.45 hm² in 2013. Besides, three independent backfillings had the trend of merging together. Consequently, the speed of controlling the geological environment had accelerated significantly.
