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.

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.
