Simultaneous operation parameters optimization technique for several main ventilation installations in mine ventilation
network is introduced over the criterion of minimum energy consumption. This technique allows automating the process
of designing energy-effective systems of mine ventilation of complex topology. At first, mathematical setting of the problem
of ventilation system parameters optimization is fulfilled. In order to analyze the problem’s alternatives, influence matrix is
additionally introduced, which allows estimating the influence of each ventilation installation on the consumption of air in
all working areas. With the use of the given matrix functional shape of master equations for ventilation installations
rotation frequency is determined. Then, the simplest possible functional type of master equations with linear proportional

link is examined. Master equations obtained are realized in the system of computer algebra Wolfram Mathematica 10.0

total input power minimization.

Key words: mathematical model; parameters optimization; main ventilation installation; energy-efficient mode of aeration;
mines of complex topology; mine ventilation network; total input power minimization.
