Abstract: The development and popularity of GIS provide a way of 3D visualization for controlling Mining Subsidence,avoding kinds of localization caused by planar data analysis. Based on ArcObjects, the paper has carried through the exploitation of the visualization system for the surface subsidence, implemented solid map display and analysis of the 3D data on the land surface move, cutaway view and the virtual display of simulative 3D terrain. It provides users more intuitionist representation form for the data information, as well as effective technique method for the production security and right decision.
