The Study On Visualization Of Mine Ventilation Simulation

Simulation is a most important technology of the management and evaluation of mine ventilation and safety , topology relationship of ventilation network automatic establishment and visualization were critical technique for mine ventilation simulation to be popularized and used. So the study on visualization of mine ventilation simulation system has important academic and actual application values .This research is a component of science tackle key problem of country the tenth five years plan, math arithmetic studied by the numbers was based on UML, and data structure and program algorithm was also studied. This paper has follow innovation:Topology relationship of mine ventilation network is automatically established and managed, passed mine ventilation topology relationship is established by man who marked tunnel start node and end node and formed a file or a database file, graph object, topology relationship and database were aparted, they were managed by programmer. The topology relationship is established and managed by sending messages between objects, all work is based object's memory address.The equilibrium graph of ventilation network is visualized. A tunnel pointer was encapsulated in rectangle which denoted a tunnel, this method keep the rectangle and tunnel seamless connection.The mine ventilation network is simplified by complex node, when the network is simplified and canceled simplification the whole graph shape was not changed, only the topology relationship was adjusted.In a general graph software, the distance of two lines which denoted the tunnel can not distinguished when the software view was zoomed to a certainty degree, so the fixed distance double line can solve this question. Regarding fixed distance double line calculation arithmetic and drawing characteristics being studied , the drawing parameter was encapsulated in tunnel object ,this reduced calculation and double line drawing parameter, and double line crossed hidden were automatically done.The study on visualization of mine ventilation is a computer system, which can deal with mine ventilation system graph and attribute data , It includes store , visual management, search, analysis, express attribute data. The system not only can mange the graph and attribute data , but also visualize the process of the mine ventilation simulation calculation.
