ABSTRACT
An option of usage of a brattice walled shaft to provide required amount of air to a mine was presented in the paper. We present methodology to calculate a diameter of such a shaft so as to the aerodynamic parameters of every compartment resulted in a equivalent resistance of the shaft equal to resistance of unobstructed 7,5 m diameter shaft.
