Simulization And Visuanlization Of Mining Subsidence Based On GIS

On the basis of probability integral method, this paper set up mining subsidence simulation and calculation method in different mining condition, and put forward data organize and transform method of mining subsidence simulation and calculation. Through Secondary development with Visual Basic and MapBasic language, develop mining subsidence simulation and calculation system. The whole system realize the inside transferring, exchanging and visual expression of the data, offer powerful computing method and analysis tools for solving mining under building, railway. The paper discuss the organization and visual expression of three dimension calculation method and subsidence data of mining subsidence, Give and appear hills and three-dimension visual prediction method in hill and low and flat area, Realize the visual expression of DEM and the earth's surface subsidence basin, probe visual overlap between three-dimension topographic map and subsidence map.
