Abstract. The necessity to transit from considering optimization of aerodynamic parameters for the main fans and mine ventilation network as definition of separate problems to consideration of the complex system «main fans - mine ventilation network» is grounded. Specific features of such complex system and basic criteria of optimization of aerodynamic parameters for the main fans and ventilation network are described. It is stated that law of resistance of separate elements in the system «main fans - mine ventilation network» can differ from quadratic law, hence leading to the changed system of equations, which describe the Kyrkhgof laws, and necessity to develop new methods for calculating the mine ventilation systems. Criteria are also proposed for estimating structural and parametric interconnection between the main fans, satisfaction of which would allow to transfer the system «main fans - mine ventilation network» to maximally sectional or fully sectional ventilation. The text material is illustrated by examples from the 1/3 Novogrodovskaya Mine.

Keywords: mine ventilation networks, main fans, criteria, interconnection between the main fans, nonquadratic law of aerodynamic resistance.
