Research on 3D tunnel modeling with drainage

Three-dimensional modeling of mine tunnel is the important content of three-dimensional modeling of deposit, but also an important means to realize the visual expression of underground tunnel, analyze spatial distribution optimization and improve mine production management. Three-dimensional modeling of drainage tunnel can more realistically reflect the real situation. Firstly, the paper analyzes the structure of the drainage tunnel, and describes data structures by using C++; Then, as semi-tunnel model for voxel, according to the symmetry modeling method, the drainage tunnel can be modeling. Meanwhile, the paper gives specific modeling steps. Using VC++ combined with OpenGL, it realizes test system of three-dimensional simulation of drainage tunnel, and verifies that the proposed modeling method is feasible.
