Abstract
The results of studying the nonuniformity effect of air flow velocity field entering the axial fan on aerodynamic parameters of main mine fans of the shafts for different configurations of input elements are presented. A parameter for estimating air velocity nonuniformity at the fan input is introduced. It is shown that dependence of total pressure and total efficiency of the fan system is linear.
