Problems solved by technology

Slotted hole focused blasting requires special drilling tools to pre-cut slots in the drilled hole, which is difficult, inefficient, and costly; while shaped charge blasting is used when the charge roll is processed, or the charge roll is loaded on site Into the energy-collecting tube with cracks, it is sent into the drill hole according to the directional fracture direction, and a through-crack is formed during blasting. However, the energy-concentrating blasting technology of the shaped-energy charge coil needs to process a special energy-collecting tube in advance, which is costly and difficult to install on site. , and the energy-gathering hole is air, light in weight and small in kinetic energy, and the effect of energy-gathering blasting needs to be improved

Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] The present invention is an energy-gathering hydraulically controlled blasting charge, such as figure 1 and figure 2 As shown, it includes a cylindrical drug roll body 3 and an outer packaging bag 1. The outer packaging bag 1 is nested with a drug roll body 3, and the two ends of the outer packaging bag 1 are closed. The drug roll body 3 includes an explosive cavity 5, a first poly The energy chamber 2 and the second energy-gathering chamber 4 are symmetrically arranged with arc-shaped surfaces inside the charge roll body 3, and the arc-shaped surfaces divide the inside of the charge roll body 3 into the first energy-gather chamber 2, the explosive chamber 5 and the second energy-gather chamber. The energy chamber 4 and the explosive chamber 5 are located between the first energy-gathering chamber 2 and the second energy-gathering ch...

Abstract

The invention discloses an energy-gathering hydraulic-control blasting cartridge. The energy-gathering hydraulic-control blasting cartridge comprises a cylindrical cartridge body and an outer packaging bag and is characterized in that arc-shaped faces are symmetrically arranged in the cartridge body, and the arc-shaped faces sequentially separate the interior of the cartridge body into a first energy gathering cavity, a dynamite cavity and a second energy gathering cavity. The energy-gathering hydraulic-control blasting cartridge has the advantages that high-pressure hydraulic jet and water wedge effect is increased by energy-gathering hydraulic-control blasting, the effects of smooth blasting or presplitting blasting are increased, dynamite use amount is reduced, blasting drilling interval is increased, drilling workload is reduced, and water mist and steam are formed during blasting to suppress dust and improve the operation environment.

Description

technical field [0001] The invention belongs to the field of blasting cartridges, in particular to an energy-gathering hydraulically controlled blasting cartridge. Background technique [0002] Conventional shaped blasting methods are mainly divided into two categories: slotted hole shaped blasting and shaped charge shaped blasting. Slotted hole focused blasting requires special drilling tools to pre-cut slots in the drilled hole, which is difficult, inefficient, and costly; shaped charge blasting is when the charge roll is processed, or the charge roll is loaded on site Into the energy-collecting tube with cracks, it is sent into the drill hole according to the directional fracture direction, and a through-crack is formed during blasting. However, the energy-concentrating blasting technology of the shaped-energy charge coil needs to process a special energy-collecting tube in advance, which is costly and difficult to install on site. , and the energy-gathering hole is air,...
