Abstract
A method of reducing the power consumption of the main mine fan through the use of partial airflow recirculation is considered. The results of numerical experiments on the calculation of air distribution are analyzed on the mathematical model of mine horizon ventilation network. The dependences of the power consumed for its ventilation on the length of horizon and the distance between the face and circulation connection are determined.
