Abstract
Provided is a method for preparing a coal mixture used for the purpose of producing coke with desired strength by taking into account the compatibility between coals for cokemaking. In the case of preparing a coal mixture, used as at least one portion of a coal blend for cokemaking, containing two or more types of coals with different surface tensions, the blending ratio of each of the coals is adjusted using the surface tension of a semicoke mixture obtained from the coal mixture as an indicator.
