3D Visualization Modeling of Coal Mine Roadway based on Visual C# and DirectX

As the most important spatial feature of coal mine, roadway occupies an important position in construction of Digital Mine (DM). 3D visualization of roadway can improves the level of management and efficiency of mine and also good for mine design of safety and environmental. In this paper, the author models the mine roadway based on Visual C# and DirectX take Dongtan mine of Shandong as example, which includes designing the data model and data structure of roadway, building the 3D visualization system of roadway to realize load data, managing data, modeling roadway and realizing simple spatial analyses to provide the basis for scientific decision-making.
