Abstract: To find a kind of air volume regulator which is effective and energy efficient, it is proposed toobtain the branch of air regulating door by linear programming model, and then obtain the resistance va.ue and fan speed by nonlinear programming model to realize the optimization of mine ventilation networkThe program is developed with Matlab, and the simulation is carried out through an instance. The resultsshow that the air volume of each branch of the mine ventilation network can meet the requirements , andthe total energy consumption of the ventilation network can be reduced. The proposed mathematical modeland method can well solve the optimization and regulation of the mine ventilation network

Key words: mine ventilation network: optimization and adjustment, linear programming: nonlinear pro-gramming
