PROBLEM TO BE SOLVED: To provide a method for producing a highly strong coke raw material, comprising dividing a massively by-produced heavy fraction into differently acting divisions, compounding the divisions with raw material coal groups having different properties, respectively, and more effectively using the compounded products as binding fillers for producing the coke. SOLUTION: This method for producing the highly strong coke raw material, comprising compounding a binding filler with a raw material coal, is characterized by (a) preliminarily dividing the raw material coal into a plurality of raw material coal groups having different properties, respectively, (b) dividing the binding filler into a plurality of binding filler groups having different strength-increasing actions, respectively, on the basis of the contents of a component soluble in hexane (HS component), a component insoluble in hexane and soluble in toluene (HITS component), and a component insoluble in toluene (TI component), (c) compounding the binding filler groups with the raw material coal groups needing the strength-increasing actions, and (d1) suitably compounding the raw material groups compounded with the binding filler groups.
