The uniform theory of a granular stratum hollows volume definition, theoretical bases of accounts of a gas pressure losses in a pole of granular materials of large height and in a stratum with smelting, account methods of equivalent gas permeability of granular materials , in view of horizontal non-uniformity of their distribution, changing of static pressure of gas on mine reactor's height, adequate three-zoned mathematical model of movement of gas in B/F are developed for the first time. Using of the developed methods of account at selection of modes of B/F charging ensuring decrease of coke consumption on 15 - 25 kg / BРof pig-iron.
