AI Technical Summary
In open-pit mine blasting, the detonating cord passing through the explosive charge will puncture the packaging bag, causing some of the explosive charge to be exposed, which will affect the effect. At the same time, it is inconvenient to connect the detonating cord and the detonating wire, and it will increase the blasting time.
A detonating device comprising a detonating coil, a detonating tube, and a fixing mechanism was designed. The detonating charge is fixed to the detonating tube through the cooperation of a fixing frame, an internal threaded block, and a positioning rod. The detonation connection mechanism enables the rapid connection of the detonating wire through the cooperation of No. 1 and No. 2 current connection components and a conductive plate.
This ensures the explosive charge is fixed vertically to prevent it from falling off, and enables rapid current transfer, thereby improving blasting efficiency and reducing alignment time.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the field of blasting technology, especially to a blasting guide equipment for open pit mine. BACKGROUND
[0002] Blasting is a technology that uses the compression, loosening, destruction, throwing and killing effects of explosive in air, water, soil and rock medium or object to achieve the intended purpose. When the explosive charge or cartridge explodes in soil and rock medium or structure, it causes compression, deformation, destruction, loosening and throwing of the soil and rock medium or structure. It is mainly used in earthwork engineering, as well as the demolition of metal buildings and structures. The research scope includes the properties and use methods of explosives and fuses, the explosive effects of charges (cartridges) in various media, contact and non-contact blasting of charges on targets, and the organization and implementation of various blasting operations.
[0003] In the process of open pit mine blasting, a detonating tube is usually inserted into the detonating agent, and a current is used to detonate the detonating tube, which may have the following problems in actual operation:
[0004] 1. Since the detonating agent and the detonating tube are placed in the hole bottom, in order to prevent the detonating agent and the detonating tube from separating during the placement process, the detonating tube is usually inserted through the detonating agent and vertically into the detonating agent. Each time the detonating agent is inserted through the detonating agent, the packaging bag wrapped on the surface of the detonating agent is punctured, causing part of the detonating agent to be exposed, resulting in different amounts of detonating agent for each detonating agent, which affects the detonation effect.
[0005] 2. Since each hole is detonated during the process of mine blasting, a connector is usually used to connect the detonating tube in each hole to the detonation line. Due to the use of current detonation effect, the detonation line and the detonating tube are usually cut, the ports are aligned and placed in the connector. This process requires some time to align, which increases the blasting time. When the alignment effect is poor, it also affects the current flow and the blasting effect. UTILITY MODEL CONTENTS
