Abstract: For an optimal management and automatic supervisory control of the mine multi-fan and multi-station ventilation system, a certain number of monitoring points should be allocated in proper sites of the system so as to provide necessary information reflecting and estimating the system operation status, which is an important part of computer's on-line optimal management.The layout of monitoring points of ventilation system is related to the number and location of monitoring points as well as the network decomposition method.A simultaneous consideration of the relation between their layout and the said three factors will complicate the issue and therefore, it is considered as a two-level question.First, the point location and network decomposition method are not considered at this time and the point number is determined by Fibonacci method; and then, at the given point number, the optimal point location is determined and further the optimum outcome of network decomposition and the largest modular difference can be got.Its practical application shows that it can make the question easy to solve with not a high computing work load.
