Studies And Applications Of Mine Ventilation System Simulation Visualization

In the coal mine accident, the heavy especially big accident is mostly related with mine ventilation. Therefore solves ventilates question to be able effectively to reduce the coal mine malignant accident. At the present, there are many problems in the mine ventilation system administration, as a result of the complexity of mine ventilation, which has brought the big difficulty for the safety control of mine ventilation. Therefore, it can obtain the mine ventilation condition quickly and accurately, and also have the great significance to reduce especially big accidence.In 1953, Scott and Hinsley firstly calculated ventilation network question by computer. In our country, Mine Ventilation Network Simulation System software developed and applied more lately. The surface and operating methods of Mine Ventilation Network Simulation System software, which compares with the commercial software, the function and surface have big differences. Meanwhile are really few to research the network parameter variety influence the entire network. The author system searched the related Mine Ventilation Network Calculate Software, which had some productions and specially analysis our country nearly ten years Mine Ventilation Network Calculate Software involve the operation platform, the user contact surface, the development language, the data storage form, the software main structure and the function etc. The author proposed the research content in this foundation. The author also have researched Mine Ventilation System Visible Simulation in the predecessor's research foundation, and solved several questions, such as it's difficult to input the mine ventilation system diagram, and the branch and node not only complex but easy to make a mistake. And provided the conveniently graph interactive interface for the user. If realized the visible input of mine ventilation system diagram and tied input and output of the data and the graphs, only input ventilation system graph not to make any simplification and while the graph input automatic establishment topology, the branch and the node will be automatic numbered and also transparent to the user Simultaneously the author utilizes the current advanced software design method and the programming technology, developed a set of Mine Ventilation System Simulation Visible Software of OpenGL Version (MVNSO) by myself, and in detail introduced the theory basic and the design thought of compiling MVNSO software relational technology and the graph draw program. The Software realized to read the AutoCAD line diagram straightly and make the mine ventilation system diagram. It's unnecessary to do these operations, such as simplification, laneway serial number, pitch point serial number to the diagram; Simultaneously provides the convenient fan management for user, the user could input the air blower performance test data or input certain spots of air blower performance curvilinear diagram directly, and draw up the air blower performance diagram of curves quickly. And there are many extra functions, such as user coulde defined the coordinate's range, move curve, local zoom, printing preview, and printing, and so on.Combine the scientific research topic "Dong Pang Mine Ventilation System optimization and reliability research", which has produced the examples of complex mine ventilation network calculation, and elaborated how to elect superiorly using several chooses of MVNSO software to mine ventilation system transformation, which can get the goal of mine ventilation network transformation and optimized. Compares the scene measured data and the MVNSO software computed result, basically tallies, thus fully has proven the software system feasibility.The article also sums up the progress and the existence question in the research, and proposes the later development direction and the improvement opinion.
