Description

Technical Field

[0001] The utility model relates to the technical field of smooth blasting, in particular to a smooth blasting charging mechanism. Background Technique

[0002] Smooth blasting is a controlled blasting technology in which the newly blasted wall surface remains flat and is not significantly damaged. Its characteristic is to drill a row of smooth blasting holes on the designed excavation contour line with the hole spacing matching the minimum resistance line, and adopt non-coupled charging or other special charging structures. After the main body of the excavation is blasted, the charges in the smooth blasting holes are detonated simultaneously, thereby forming a smooth and flat excavation surface that penetrates the smooth blasting holes.

[0003] After retrieval, the application number of the Chinese patent document is CN202221963252.0. This utility model relates to a charging device for smooth blasting, belonging to the technical field of roadway tunneling blasting. It includes a charging pipe, in which cartridges are loaded. On both sides of the outer pipe wall of the charging pipe, a plurality of arc-shaped notches are symmetrically arranged at intervals. The charging pipe is provided with an arc-shaped groove plate for covering the arc-shaped notches. One end of the charging pipe is internally provided with a detonator, and the detonator is connected with a detonating cord. The detonating cord is laid along the entire length of the inner wall of the charging pipe and is in close contact with the cartridges, and is led out from the port of the charging pipe. The purpose is to load the cartridges into the charging pipe provided with arc-shaped notches. Under the action of the arc-shaped groove plate, the cartridges at the arc-shaped notches form a circular-shaped shaped charge concave surface. After the charge is detonated, a shaped charge effect will be formed, and the explosive energy will be more concentrated in the direction of the rock mass contour surface, playing a role in cutting the rock mass, thereby effectively reducing the damage to the reserved rock mass and facilitating the formation of a regular contour surface.
