Abstract

Provided is a method that is for preparing blast furnace blow in coal and that can at a low cost obtain blast furnace blow in coal that suppresses occlusion by blast furnace blow in ash or accretion of blast furnace blow in ash in a pathway leading to a tuyere of a blast furnace main body while suppressing a decrease in the amount of heat release. On the basis of data obtained by means of analyzing coal a first and second coal type satisfying conditions (A,B) are selected (S2,S3) on the basis of the CaO content in the ash of the first and second coal types when the oxides of Al Si Ca and Mg in the ash is 100 wt% and the AlO content in the ash is 20 wt% the mixing ratio of the first coal type and second coal type that results in the CaO content in the ash of the mixed coal resulting from mixing the first coal type and second coal type being at least 40 wt% is derived (S4) and the first coal type and second coal type are mixed (S5) at the mixing ratio.
