There are serious mining subsidence around Longgu coal mine, local people's livelihood has been affected seriously. Remote sensing technology was used to survey the mining subsidence, because it is macroscopic, rapid, economic, effective and objective. There were 6 period remote sensing images were collected in total. Those remote sensing images were compared, and the history about those mining subsidence was known. Filed investigation were applied in this articles to survey these mining subsidence, also. The area of these mining subsidence destroyed were: 0.35km2 in December 2010, 0.56km2 in August 2011, 1.01km2 in September 2012, 1.26 km2 in May 2013, 1.53km2 in November 2013. There were a rapidly develop in the four years. The mining subsidence in this area belong to the young type, developed rapidly, trend to destroy great deal farmland during a short period. The mining subsidence should be monitored persistent use remote sensing. The regular about mining subsidence should be further study. And some prediction works should be done based on the regular study.
