Abstract
A method of producing a coal mixture includes blending a plurality of coals, wherein formula (1) and formula (2) are satisfied:αcalc≤1.2×10−10 (mol/g-coal) (2) wherein αcalc is a hydrogen ion release capacity per unit mass (mol/g-coal) of the coal mixture, αi is the hydrogen ion release capacity per unit mass (mol/g-coal) of a coal i, xi is a blending ratio of the coal i blended in the coal mixture, and N is a total number of brands of coal contained in the coal mixture.
