Problems solved by technology

[0003] When two-way energy-concentrating blasting is used, the air medium coupling is used in the spare part of the borehole, and the high-temperature airflow generated is likely to cause a gas explosion accident, and more toxic and harmful gases (CO and NOx) are produced, and the dust concentration is relatively large, which is not conducive to the safety of workers.

Abstract

The present disclosure relates to a cumulative energy hydraulic blasting device. The cumulative energy hydraulic blasting device includes a cumulative energy tube, an explosive package, water bags anda lead wire; the cumulative energy tube is in the shape of a hollow cylinder, a plurality of cumulative energy holes are respectively arranged in the two opposite sides of the cumulative energy tube,and the plurality of cumulative energy holes are distributed along the axial direction of the cumulative energy tube; the explosive package is arranged in the cumulative energy tube, and a detonatoris arranged on the explosive package; the water bags are arranged in the cumulative energy tube and are located at two ends of the explosive package; and the lead wire is connected to the detonator and is led out from the cumulative energy tube. The cumulative energy hydraulic blasting device provided by the present disclosure can effectively avoid gas explosion, has a stronger blasting effect onrocks, and reduces a dust concentration.

Description

technical field [0001] The present disclosure relates to the technical field of directional pre-splitting slits, and in particular, to an energy-gathering hydraulic blasting device. Background technique [0002] The self-forming lane without coal pillars has been used in many mining areas across the country and has been promoted on a large scale. Roof directional pre-splitting blasting technology is one of the core technologies of this construction method. At present, two-way concentrated energy tensile blasting is mainly used for roof cutting. [0003] When two-way energy-concentrating blasting is used, the air medium coupling is used in the spare part of the borehole, and the high-temperature airflow generated is likely to cause a gas explosion accident, and more toxic and harmful gases (CO and NOx) are produced, and the dust concentration is relatively large, which is not conducive to the safety of workers. In good health. [0004] It should be noted that the informatio...
