A Visible Research About Graph And Data Of The Mine Ventilation

This paper is based upon XiShan Colliery Parent Company [DongQu Mine Pit Ventilation Network Computer Management System ] .The data of DongQu Mine pit ventilation resistance mensuration is combined. And system theory, graph theory, ventilation network technology and computer technology are utilized. According to the reality of coalmine, we think that graph and database is incorporate in mine ventilation system. So based on this, ventilation system standard graph is founded, the tool of ventilation graph to draw is made, the ventilation network calculation is realized, the outcome of the ventilation network calculation is seen on the screen, and opaquing and inquiring of the road parameters and so on. In addition to mine ventilationdrawing-database visual management system is developed. For displaying reliability and utility of this system, at last we take an example that the procedure is putted to the DongQu Mine.The characteristic of this paper is with the language of Visual Basic Application as a development tool. A system of graph and tunnel parameter is established. The arithmetic of the ventilation system network calculation and the joint way of drawing and database has been improved. And the stability of the arithmetic, and the modifying and updating ability of the mine ventilation graph are raised. It makes technical people more convenient, more prompt to modify graph parameters. So it has realized the unification of drawing and data management. This has embodied the flexibility of the data change in mining enterprise production.
