Peripheral eye charge device for smooth blasting

Abstract

The invention discloses an explosive loading device for holes at the periphery of a smooth blasting. The device comprises a hole blockage body and an explosive loading body; the explosive loading body is provided with energy-concentrated grooves, an energy-concentrated hole, explosive bins and partition boards; the hole blockage body is positioned at one end of the explosive loading body; the energy-concentrated grooves are circular arc-shaped, are symmetrically distributed on two sides of an axis of the side surface of the explosive loading body, and protrude towards the interior of the explosive loading body; the energy-concentrated hole adopts a V-shaped structure, positioned at one end of the explosive loading body, which is far from the hole blockage body, and is sunk towards the interior of the explosive loading body; the explosive bins are long cylinder bodies with the top surface opened and are multiple in number; the explosive bins are separated through the partition boards. The explosive loading device can achieve the aims of accurately controlling explosive loading amount, positioning blasting and saving explosive consumption.

Description

Technical field: [0001] The invention relates to a device for quantitative charging of the peripheral eye of smooth surface blasting, especially a device capable of controlling the amount of charge and the distance between charges and fully exerting the blasting power of explosives. Background technique: [0002] At present, in the blasting construction of my country's engineering construction, large-scale charging equipment is generally used for large-scale charging equipment for projects with a large amount of charge at a time, which reduces the accuracy of charge control, and the specific position or spacing of charge in the blast hole is controlled inaccurately, which seriously affects Blast mass effect. Especially in the tunnel blasting operation, there is a high requirement for the contouring of the tunnel periphery after blasting. However, at present, the charging of tunnels is basically controlled by manual use of gun rods, and some tunnels are controlled by manually ...

[0002] At present, in the blasting construction of my country's engineering construction, large-scale charging equipment is generally used for large-scale charging equipment for projects with a large amount of charge at a time, which reduces the accuracy of charge control, and the specific position or spacing of charge in the blast hole is controlled inaccurately, which seriously affects Blast Mass Effect

Especially in the tunnel blasting operation, there is a high requirement for the contouring of the tunnel periphery after blasting. However, at present, the charging of tunnels is basically controlled by manual use of gun rods, and some tunnels are controlled by manually binding explosives on bamboo chips. It is difficult to ensure the stability and spacing of the explosive binding, and it destroys the qualified state of the explosive when it leaves the factory. During the charging process, it is difficult to hit the preset blasthole position due to the softness of the bamboo pieces.

This makes it difficult to meet the quality control requirements of tunnel blasting, and wastes explosives and labor, resulting in huge cost input
