AbstractIn recent years GIS has been widely used in the mining and management of coal. The establishment technology of three-dimensional model for the mine is mature gradually, and it can not only make the mine visualization, but also provide rich information than two-dimensional plane figure. Although ArcGIS don’t have a complete set of three-dimensional to mine design, it has the function that includes three-dimensional visualization, grade calculation, calculation of reserves, spatial attribute query and analysis and other functions. As one of the secondary development of the worlds largest platform, ArcGIS will have a very big development space aiming at the demand of the digital mine.The paper uses ArcGIS as modeling platform in HanDaGai forest farm coal mine. The original topographic map data is generated in the software platform of MapGIS, and then stratifies geological graphics, digitizes the separated layer using R2V software, finally saves as format of shp of digital graphics which can be identified by ArcGIS software. TIN model is setting up in ArcScene module using its contour properties, then interpolates to its internal, so generates surface model of DEM, analyze the space (slope mining shadow, curvature analysis, slope aspect analysis, etc.) using DEM raster image. In the process of building geological model, database which is based on the space coordinate system is setting up on the basis of space parameters about exploration dataand drilling data, surface model of each formation is established by interpolation, ore body to the surface models is constructed using the basic principle of tri-prism model. Finally the grade of TFe, MFe and Cu ore bodies in C2 are estimated according to the average drilling grade of high magnetic anomaly zone in C2, using ordinary kriging interpolation, on the basis of exploring geological statistics.Three-dimensional visualization model plays a crucial role to the production in HanDaGai forest farm coal mine, and also ha
