Abstract :
Tunnel modelling is one of hot research areas on digital mine. Analyzing the basic elements and the topological relationship of the 3D tunnel model, 3D tunnel model with collapsible fractures is proposed. Data model of 3D tunnel is conducted in-depth study; data structure of 3D tunnel model with collapsible fractures is defined, and the key issues of the model are studied. On that basis, modelling method of the 3D tunnel model with collapsible fractures is detailed studied, and it is carried on programming with Java3D. The result shows that, 3D tunnel can be reasonably described with the model, and the model can be used to model the 3d mine geography network and to analyze the applications based on the 3D mine geography network.
