摘要： PROBLEM TO BE SOLVED: To provide a repairing method for preventing a tapping hole from being damaged by sufficiently filling a brick joint, crack and a cave with a repairing material without using a special device, and to provide a repairing material to be used therefor. SOLUTION: In a method for repairing the tapping hole by forming a bore 7 into a predetermined depth in the tapping hole 11 blockaded with a mud material 10, with a drill, and then pressing a soft repairing material 5 mainly containing a fire-resistant fine powder and a carbonaceous binder into the bore 7 with a mud gun 1, this repairing method comprises: charging the repairing material 5 in front of a cylinder 2, and charging a hard material 6 harder than the repairing material 5 behind it; and when pressing the repairing material 5 into the bore 7, pressing the repairing material 5 through the hard material 6 with the use of a piston pressure from the backside of the hard material 6, to press the repairing material 5 into the bore 7. The repairing material 5 mainly contains 50 to 85 mass% of fire-resistant fine powders with a grain size of 1 mm or smaller and the carbonaceous binder, and the fire-resistant fine powder contains at least 50 mass% of graphite fine powders with respect to the total weight of the fire-resistant fine powder and the carbonaceous binder.
