Research On Visualization And Appraisal Of Mine Subsidence Damage Based On MGIS

In this thesis,it presented the current situation of Mine Geagraphic Information System and the necessity and significance of MGIS technology applied in Mine Subsidence,analyzed the theory of Mine Subsidence, and choosed the method of probability integral in the end,realized the Mine Subsidence Damagement Evaluating System based on MGIS by the 0bject－0riented develop language,which mainly included Mine Subsidence Forecasting sub-system and Mine Subsidence Damagement Evaluating sub-system and followed strictly the principle of software engineering and the viewpoint of systematic theory.Analyzed the current situation of 3D GIS at home and abroad and realized the 3D simulative system based on ArcView GIS.Besides, the collecting methods of space data and attribute data are given,and elaborate in detail the theory and technology relevant to the system.At last,take the QINGHEMEN Mine for example and tested that the method is practical.
