Abstract: This paper proposed a new loop controller optimization method based on the study of the common solution method for mine ventilation network.The core ideologies of the algorithm is that it uses the minimum power line channel under non-equilibrium state as a benchmark，and then each channel of the ventilation network is adjusted in accordance with the minimum spanning tree method，and this process will continue until the channel is no longer adjustable up.The ventilation network solution optimized mathematical model established by this method can not only get the best adjustment amount and position theoretically which guaranteed the minimum total power consumption in the mine，but also provide a new method and means for selecting the main fan condition，optimizing the location and condition of underground stations，optimizing the adjustment position and so on.
