Description :
Subsidence occurred in many parts of the world, particularly in densely populated deltaic regions, causing extremely expensive damage. It can be resulted from natural causes, man-made induced causes, or other mixed causes. For identifying surface subsidence, many techniques have been employed. With the development of GIS techniques, identification of surface subsidence is becoming a relative easy problem. Ruqigou coal mining area was selected as a case study to identify the surface subsidence with DEM (digital elevation model) overlaying techniques. Discussion of the results.
