Abstract: One of the objectives pursued by the designers in departments of mine geology, mining and others has grown to how to build a CAD system of 3D Geological Survey with simple operation and powerful function to realize the auto-formation of 3D deposit models. In view of this, a variety of mathematical methods, database technology, graphics-video processed technology are comprehensively applied to deeply study the overall framework and implementation method with software of CAD System of 3D geological survey. Also the paper took an eventful attempt to research the focus and nodus, automatically drawing the boundaries of mineral rock and auto-formation of the 3D deposit models, in the CAD System of 3D geological survey. Then an auto-formation method of 3D deposit models based on the surface-fitting method of spatial little triangulated surfaces is proposed, which provides a totally new platform for mine geologists and miners.
