Abstract
An explosive cartridge includes a substantially cylindrical sleeve ( 2 ) having an end wall ( 6 ) sealing a first end of the sleeve, an end unit ( 3 ) inserted in the sleeve to a certain depth in a second end of the sleeve, said end unit having an inner side ( 4 ) facing the interior of the sleeve and an outer side ( 5 ) on the opposite side of the end unit, a chamber ( 7 ) in the sleeve between said end wall and said inner side, said chamber being filled with a blasting agent ( 8 ), a channel ( 10 ) extending through the end unit between an outer mouth ( 11 ) and an inner mouth ( 12 ), said channel comprising a seat ( 13 ) for a priming cartridge ( 14 ), and a priming cartridge accommodated in the seat, said priming cartridge containing a detonating explosive for the firing of the blasting agent in said chamber. At least one spacing member ( 20 ), protruding in the axial direction, is provided on the outer side of the end wall ( 6 ) in the first end of the explosive cartridge and/or on the end unit in the second end of the explosive cartridge, such that an intermediate space ( 28 ) is formed between the outer side ( 5 ) of a first, lower explosive cartridge and the under side of the end wall of a second, upper explosive cartridge resting on the first explosive cartridge, when the two cartridges are entered in a drill hole ( 24 ) in order to be detonated, and at least one passage ( 21 ) is provided in the radial direction, passing said spacing member, allowing communication between said intermediate space and the surrounding space ( 27 ) in the drill hole.
