Visualization Modeling of Mine Roadway Based on Visual C#

As the most important spatial feature of coal mine, roadway takes an important part in construction of Digital Mine (DM). If the roadway can be modeled in 3D visualization, people will get its 3D graphic and know the engineering change accurately and in time, not only these, it also helpful for showing the spatial relationships of excavation engineering and orebody, wall rock even the surface diggings. So, 3D visualization of roadway can improve the level of management and efficiency of mine and also good for mine design of safety and environmental. Take the roadway data of Dongtan mine of Shandong as example, this paper mainly researches the data processing - arithmetic, modeling method and visualization analyses of roadway based on Visual C# and DirectX 9.0 C. In detail is building every regular roadway according to the key points of it to realize modeling the 3D roadway through the process of pointrarrlinerarrfacerarrsingle roadwayrarrmulti-roadway. And then combined with the technology of texture mapping and light setting, the author solved some problems of joining the roadway at the turning points and doing some spatial analyses.
