摘要

Three-dimensional roadway models are the foundation of virtual mine systems. Triangulations are most common methods for building 3D roadway. 3D visualization analysis functions, such as emergency rescue line simulating, personnel position path tracking, and ventilation simulation were carried out based on topological relations and attributes between these roadways. To solve these problems, several algorithms were proposed. The key issues were how to build the triangle model at the roadway junction, how to build the different roadway pattern. Finally, Dijkstra's Algorithm is finally used to realize the coal mine emergency rescue line simulating. A virtual mine system has been developed with function of emergency dispatching, disaster prediction and early warning, emergency safeguard and supervision and management.
