PURPOSE: A maintenance jig for a detonator combining hole and a waste cartridge case maintaining method using the same are provided to reduce costs for bomb maintenance by equipping the detonator combining hole which is expanded to be bigger than reference standard such that the detonator combining hole is suitable for standards during replacement of a propelling charge and a detonator of the bomb. CONSTITUTION: A maintenance jig for a detonator combining hole comprises a supporting body(100), a press-fitting body(200), and a pressure transmitting body(300). The lower part of a cartridge case(30) is supported in the supporting body. The press-fitting body is formed to be smaller than the inner diameter of the cartridge case to be inserted into a groove(31) of the cartridge case. The press-fitting body receives pressure from a push unit(400) while being inserted into the groove, thereby pressing an outer area of a detonator combining hole. The pressure transmitting body is formed on the top of the press-fitting body and delivers the pushing force from the push unit.
