The Research Of Jin Chuan Er Kuang Multi-stage Fan Station Ventilation

For the research of the Jin Chuan Er Kuang Mine Ventilation Simulation System, the advantage and disadvantage of multi-fan-station ventilation, for the dissertation of Er Kuang multi-stage fan station ventilation, aim at the existing problems,explaining the necessity of multi-stage fan station ventilation, and on condition that how to use multilevel fan station to ventilation effective and economical. When using multi-stage fan station to ventilate, circulation wind is inevitable, it cause the algorithm of using Path matrix without unidirectional circuits invalidate,by now it must use Depth-first search algorithm to find path,equilibrium diagram is a new method to express the character of ventilation network,the function of the equilibrium diagram is discussed particularly. For the many assist fans in combined-operation in JinChuan Mine working area returning well, using genetic algorithm to select assist fans to fix on the pressure and the position is brought forward. Through the test of the fan character, using the method of draw the fan performance curve to analyze the problem of the many fans in combined-operation. Finally,for the existing problem,the optimization and alteration is brought forword.
