Unreasonable exploitation and administration of underground engineering are a great menace for people's lives and properties. The traditional handmade safe administration can't meet the need of the modern development, which will strongly accelerate the development of a dynamic, visual and interactive 3D administrative system. But present GIS technology has its disadvantages in solving the 3D problems, which greatly restrict the application of GIS to the underground engineering. This paper projects the surface safety visualization administration system of underground engineering. It studies on the establishment and arithmetic of 3D spatial TIN side slice model, and puts forward a mixture modeling method with the 3D spatial data of surveying and multilayer TIN side slice, and adopts point cushion analysis with restriction conditions and fill-in arithmetic to realize the combination of graph and data. It displays data from multi-dimensions, reveals the relations between data and analyzes the information behind the data by visualization platform, and discusses the process of data collection, data analysis, data modeling, topological modeling and three dimension deformation visualization based on a project in Tang Mei company of Zi Xin Bureau of Coal in Hunan. and provides. It can provide the government and the related departments with an alternate visualization platform for safety analysis and decision support.
