Abstract

Provided is a method that is for blending a blended coal for coke production and that using physical properties that had not been conventionally taken into consideration as indicators estimates the strength of coke produced with a blended coal as the starting material and thereby is able to suppresses an increase in starting material cost of the blended coal at the same time as increasing the strength of the coke. At least two grades of coal are blended to result in a blended coal for coke production. When blending the at least two grades of coal the grades of coal and the blending percentage of the grades of coal are determined using as a management indicator the surface tension of each heat treated grade of coal.
