Zusammenfassung:	PURPOSE:To provide a bag body for loading explosive in blasting device for rapturing remaining pig iron in a blast furnace to be repaired through blasting. CONSTITUTION:A tubular bag body 1, into which explosive is loaded, is made of textile made of fire resistant and heat resistant fibers such as ceramic fibers and the like, while heat resistant water stopping material 4, such as silicon rubber and the like, is stuck to the inner surface of the same through coating. The length and the diameter of the bag body is formed so as to be larger than the depth and diameter of a blasting hole 11 and the bag is inserted into the blasting hole 11 after loading explosive 7 into the tubular bag body 1, then, the explosive is exploded under a condition that cooling water is supplied into the bag body 1 to expand it.
