The Virtual Reality System For The Coal Mine

The cricumstance of the coal market keeps on heat in the last few years. So the mining speed comes to an unprecedented degree, but the safty measures can not keep up with the speed.As result, the coal mine's accidents take place again and again. As soon as possible improving the coal mine environment, constucting modern mines, increasing mine's information degree and so on, become our important work. The degree paper topic is about this.The paper has two aspects: Firstly, it expatiates the theory of ventilation system and the standards for the ventilation network computing. Then the paper makes an intensive study of the modules extent and controlling. At the last, the program for the ventilation network computing has been achieved. The program is independent. The fixed draft and accuracy can be controlled.Secondly, the paper introduces the ventilation system. Then it introduces the 3D model frame, and constructs the 3D model database for the mine ventilation system. Then the paper achieves the virtual reality for mine ventilation system. The visibility is 3D, but the tradition is 2D.In the last, the paper has achieved the two important parts. It has great realistic meaning and farsighted strategy meaning for increasing mine's information degree.
