PROBLEM TO BE SOLVED: To provide a method for repairing damage of the brick walls in a carbonization chamber of a coke furnace that improves the efficiency of repairing the damages of the walls in the carbonization chamber such as tile joint breakage or tile cracking and can inhibit the incomplete combustion or black smoke occurrence due to leakage of the coke furnace gas into the combustion chamber. SOLUTION: When the carbonization chamber is repaired by blowing fine particles of a fire refractory material (dusting material) in the carbonization chamber, two kinds of dusting materials having different particles sizes from each other are used. At first, a dusting material containing >=40% of the particles of 74μm or larger particle sizes (the coarse material) is blown, and subsequently another dusting material containing >=80% of less than 44μm particle sizes (conventional dusting material) is blown.
