Accurate positioning blasting system

Abstract

The invention discloses an accurate positioning blasting system. The accurate positioning blasting system comprises an installation positioning cylinder, arc-shaped clamping plates used for clamping blasting explosives and telescopic rods, wherein the installation positioning cylinder is of a horizontally-arranged cylinder structure; a semicircular inner cavity is formed in the installation positioning cylinder; the bottom end face of the semicircular inner cavity is arranged to be a horizontal plane; the arc-shaped clamping plates are symmetrically arranged on the inner walls of the two sidesof the semicircular inner cavity; the arc centers of the two sets of arc-shaped clamping plates are oppositely arranged towards the blasting explosives; the two sets of telescopic rods are welded between the opposite side faces of the two sets of arc-shaped clamping plates and the inner wall of the semicircular inner cavity; the peripheral sides of the two sets of telescopic rods are sleeved withcompression springs; and the two ends of the compression spring are in contact with the arc-shaped clamping plate and the inner wall of the semicircular inner cavity correspondingly. According to theaccurate positioning blasting system, the blasting explosives can be conveniently placed, the clamping and positioning effects are achieved, loosening displacement of the blasting explosives is reduced, and the stability and the precise blasting performance of the blasting explosives are improved.

Description

technical field [0001] The invention belongs to the technical field of blasting, and in particular relates to a precise positioning blasting system. Background technique [0002] This embodiment takes mine blasting technology as an example. The purpose of mine blasting is to blast ore rocks to ensure the normal operation of ore mining. In the development process of mine blasting technology, the explosives used in mine blasting are also constantly developing, such as black powder, Nitroglycerin explosives, ammonium nitrate powder explosives, ammonium oil explosives, slurry explosives, and emulsion oil explosives are currently commonly used as ammonium nitrate explosives, which are detonated at regular intervals through the circuit. However, ammonium nitrate explosives are dangerous goods. , stable positioning and fixing are required during installation and use. [0003] The traditional blasting technology of ammonium nitrate explosives usually needs to manually place the exp...

AI Technical Summary

Problems solved by technology

[0003] The traditional blasting technology of ammonium nitrate explosives usually needs to manually place the explosives in the circular holes punched in advance in the area to be blasted. However, this method is relatively simple and lacks a positioning installation structure. The vibration caused by blasting in other mines, It is easy to cause the explosives without positioning and installation structure to shift or even fall, which will affect the normal blasting work
