The increase of energy efficiency of main fans (MF) work is the basic condition of perfecting the mine ventilation system. During realization of multi-fan ventilation there is the non-productive «overbalancing» of vent flow from a weaker towards more powerful ventilator which causes decline of work efficiency of both. The questions of reducing the MF mutual influence on the outgoing air flow and increasing the aerodynamic quality of vent network have been studied and considered insufficiently. It is proposed to use the method of calculating the effective MF operating conditions taking into account the mutual influence of MF and areas-users of fresh air in mine ventilation network and on the basis of criterion of estimating the MF mutual influence, which will allow to enhance the energy efficiency of mine ventilation and labour safety of subsurface miners.
