A general non-linear programming mathematic model to solve problems related to optimal control of mine ventilation network has been established, in which the target function is power consumption of main fans and regulators, the constraint equations to be met are air quantity balance equation, air pressure balance equation, regulating ability of branch airway, the upper and lower limits of air quantity and regulation. The constrained variable metric method(CVM), one of the most efficient methods available is chosen for solution of this model. The software is written in C language, which is run under Microsoft Windows. It is characterized by advanced algorithm, fast convergence, high reliability ,ease and wide application. It is proved by examples that this software is applicable in solving all kinds of air flow control problems of the mine ventilation network.
