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.

Claims (5)

1. Взрывной патрон, содержащий по существу цилиндрическую гильзу (2), имеющую торцевую стенку (6), плотно закрывающую первый конец гильзы; концевой блок (3), вставленный в гильзу на определенную глубину на ее втором конце и имеющий внутреннюю сторону (4), обращенную внутрь гильзы, и наружную сторону (5) с противоположной стороны; камеру (7), расположенную в гильзе между указанной торцевой стенкой и указанной внутренней стороной и наполненную бризантным взрывчатым веществом (8); канал (10), проходящий через концевой блок между наружным входным отверстием (11) и внутренним входным отверстием (12) и содержащий гнездо (13) для запального патрона (14); и запальный патрон, расположенный в этом гнезде и содержащий детонирующее взрывчатое вещество для воспламенения бризантного взрывчатого вещества в камере, отличающийся тем, что на наружной стороне торцевой стенки (6) на первом конце взрывного патрона и/или на концевом блоке на втором конце взрывного патрона имеется по меньшей мере один разделительный элемент (20), выступающий в осевом направлении так, что между наружной стороной (5) первого, нижнего взрывного патрона и нижней стороной торцевой стенки второго, верхнего взрывного патрона, опирающегося на первый взрывной патрон, когда эти патроны вставлены в буровую скважину (24) для их детонации, образуется промежуточное пространство (28), и имеется по мере один проход (21), проходящий в радиальном направлении мимо этого разделительного элемента и сообщающий указанное промежуточное пространство с окружающим пространством (27) в буровой скважине, в результате чего ударная волна или ударный импульс, созданный в жидкой или гелевой текучей среде (26), окружающей взрывной патрон в буровой скважине, может передаваться через указанный по меньшей мере один проход за указанный разделительный элемент в указанное промежуточное пространство для воспламенения запального патрона.1. An explosive cartridge containing a substantially cylindrical sleeve (2) having an end wall (6) tightly covering the first end of the sleeve; an end block (3) inserted into the sleeve to a certain depth at its second end and having an inner side (4) facing inward of the sleeve and an outer side (5) on the opposite side; a chamber (7) located in the sleeve between the specified end wall and the specified inner side and filled with blasting explosive (8); a channel (10) passing through the end block between the outer inlet (11) and the inner inlet (12) and containing a socket (13) for the ignition cartridge (14); and an ignition cartridge located in this nest and containing a detonating explosive for igniting a blasting explosive in the chamber, characterized in that on the outer side of the end wall (6) at the first end of the explosive cartridge and / or on the end block at the second end of the explosive cartridge at least one separation element (20) protruding in the axial direction so that between the outer side (5) of the first, lower explosive cartridge and the lower side of the end wall of the second, upper explosive cartridge, adjacent to the first blasting cartridge, when these cartridges are inserted into the borehole (24) to detonate, an intermediate space (28) is formed, and there is at least one passage (21) that passes radially past this separation element and communicates the specified intermediate space with the surrounding space (27) in the borehole, as a result of which the shock wave or shock pulse generated in the liquid or gel fluid (26) surrounding the blasting cartridge in the borehole can be transmitted through the specified m at least one passage for the specified separation element into the specified intermediate space for ignition of the ignition cartridge. 2. Взрывной патрон по п.1, отличающийся тем, что запальный патрон относится к типу патронов с центральным воспламенением и расположен на определенной глубине в указанном канале, причем задняя часть запального патрона находится на некотором расстоянии от наружной стороны концевого блока, так что наружный участок (17) канала (10) сообщается с указанным промежуточным пространством (28) и наполнен текучей средой, когда она заполняет это промежуточное пространство.2. An explosive cartridge according to claim 1, characterized in that the ignition cartridge is of the central ignition type and is located at a certain depth in the specified channel, the back of the ignition cartridge being at some distance from the outside of the end block, so that the outer section (17) channel (10) communicates with said intermediate space (28) and is filled with fluid when it fills this intermediate space. 3. Взрывной патрон по п.1 или 2, отличающийся тем, что указанный канал и его наружное входное отверстие расположены в центре, а разделительные элементы (20) находятся снаружи канала, если смотреть в радиальном направлении.3. An explosive cartridge according to claim 1 or 2, characterized in that said channel and its external inlet are located in the center, and the dividing elements (20) are located outside the channel when viewed in the radial direction. 4. Взрывной патрон по п.1 или 2, отличающийся тем, что высота разделительного элемента или разделительных элементов не больше половины длины запального патрона, но не меньше чем 10% его длины.4. Explosive cartridge according to claim 1 or 2, characterized in that the height of the separation element or separation elements is not more than half the length of the ignition cartridge, but not less than 10% of its length. 5. Взрывной патрон по п.1 или 2, отличающийся тем, что длина разделительного элемента или разделительных элементов не больше длины наружного участка канала (10) между запальным патроном и наружной стороной концевого блока, но не меньше 10% длины этого наружного участка (17) канала.5.
