Integration Method of Three-dimensional Complex Tunnel Network Model

Abstract—In recent years, “Digital Mine” has been an important research direction in the field of geology and mineral resources. In particular, three-dimensional network modeling of mine tunnel with its spatial analysis is an important research perspective. It is significant research direction on theoretical study of “digital mine”, mineral resources exploration, mining decision-making management, mine production and mine safety etc. In order to seamlessly integrate the models of simple tunnel and intersected complicate tunnel, directed double nodes approach and midpoint interpolation approach were proposed; In order to solve the problem that the two corresponding half-tunnels will crack at sharp turning, the uniform height approach on section arch was proposed. Using Windows XP as the platform, MS Visual C++6.0 as development tools and OpenGL graphics package as the graphic processing display tools, the experimental system of three-dimensional tunnel network model was designed and developed. Using real mining data, the experimental system was tested. It is shown that the proposed method is the practical and effective.
