| description | The spacer in the blast hole comprises a long-strip-shaped air column, an upper air chamber and a lower air chamber are arranged in the air column, the air chamber located on the upper portion is in an annular shape, so that a powder filling groove is formed in the middle of the air chamber, the upper portion of the powder filling groove is opened to form a powder filling opening, and the spacer further comprises a cloth sleeve. And the cloth sleeve at least wraps the peripheral surface of the air column. According to the gas column, the arrangement mode of the upper gas chamber and the lower gas chamber is adopted, the upper gas chamber is used for containing explosives, the distance between the cartridge bag and the hole wall is controlled through the thickness of the gas chamber, the distance between the cartridge bag and the hole wall can be effectively controlled, it is guaranteed that the cartridge bag is located in the center of the hole, and therefore the effect generated by explosion of the cartridge |
