Each influence factor had the obvious fuzzy characteristic in view of the mine ventilation system, the utilization fuzzy mathematics method has established one kind of new ventilation system rationality fuzzy mathematics judgment model, carried on the synthesis judgment to the ventilation system rationality, this judgment method could give the quota description direct-viewing to the system rationality. Finally, take some mining bureau's four ore as the example, has confirmed the model rationality. This method may operational strong, the effect be better, may in the general mine ventilation system appraisal the widespread application.

Selecting the optimal air regulation scheme of mine ventilation network, the essence is to choose the network a most optimal tree and obtain the corresponding optimal cosine tree combination program.Due to a synthetic consideration of the influence of production.Management economy and other aspects on the tree selection,the air flow regulating and controlling system made by the authors is optimum It is satisfactory to use the model for the north part ventilation system of Laochang tin mine of Yunnan tin Industrial crop. It is of practical significance to combine organically air flow regulating and controlling system with mine ventilation system.

The Stability

The stability of mine ventilation system has a significant impact on coalmine safety production. It is not only an important index of ventilation system quality, but also an important safety index of coalmine. The author made an analysis of ventilation system stability on the basis of test on Yaoqiao coalmine ventilation system resistance and indicated that the ventilation system of this coalmine existed some problems, which had an important meaning for enhancing the management of mine ventilation system and directing the normal, safe production.

The fuzzy Fault Tree Analysis (FTA) of mine ventilation system is set up based on thorough composition of the system, with triangular fuzzy number being used as probability of elementary event and “mine ventilation system fault” being deemed as top event. In this paper, the reliability of FTA has been analyzed and applied to a mine in Gansu Province. The result shows that the minimum cut set of fault tree is 549 and the main reason why it has a huge number of minimum cut set is Level 1，Event 7，“Monitoring feedback system failure”. The reliability of top event and Level 1 event is low, and fuzzy failure probability of top event is (0.009, 0.014, 0.009), the maximum of which is 2.3% of it. The degree of fuzzy importance of elementary event is the highest in Level 1，Event 7. The maximum of fuzzy importance is 0.0843 by the normalization and the rest vary from 0.0050 to 0.0100 mostly.

In the work study results of influence of typical working junction angle on amount changing of local aerodynamic resistances when air flows in different directions is represented. Using finite-element software, aerodynamic parameters of elements of mine ventilation network is obtained and is compared with analytical calculations Interinfluence local aerodynamic resistances located at ventilation network consecutively in normal and reversing behavior is discovered. It allows to increase accuracy of calculation of mine ventilation network at emergency ventilation operation.
