Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of slope blasting, in particular to a single-hole interval blasting mine slope protection structure. BACKGROUND

[0002] Blasting is a technology that uses explosives to produce compression, loosening, destruction, throwing and killing effects in air, water, soil and rock medium or objects to achieve the desired purpose. When the explosive charge explodes in the soil and rock medium or structure, it causes compression, deformation, destruction, loosening and throwing of the soil and rock medium or structure, mainly used in earthwork engineering, as well as demolition of metal buildings and structures. Blasting is needed during mining.

[0003] Publication No. (CN216815216U) discloses a single-hole interval blasting mine slope protection structure. During the blasting process, the strong impact force will cause the touch pressure piece to move inward at the same time and extrude the inflatable bag. A small amount of gas in the inflatable bag flows upward through the connecting pipe, blowing the floating ball away from the connecting pipe. At this time, through the gas supply equipment, the gas can be blown inward through the air inlet, relieving the impact on the touch pressure piece, promoting the uniform breaking of the hole wall and hole rock, preventing the hole from being punched, improving the blasting effect, and reducing the damage rate of the slope during the blasting process. The above device still needs to be connected to the gas supply equipment during operation, and the use effect is not good, which needs to be improved. UTILITY MODEL CONTENT
