Blast hole uncoupling energy gathering spacing device suitable for non-coal mine mountain and using method thereof

Abstract

The invention relates to a blast hole uncoupling energy gathering spacing device suitable for a non-coal mine mountain and a using method thereof. The blast hole uncoupling energy gathering spacing device suitable for the non-coal mine mountain comprises a tray body, upper barbs and lower barbs, the upper barbs and the lower barbs are arranged on the periphery of the tray body and used for clamping the hole wall, the tray body comprises an inverted conical disk body and an internal thread column arranged on the upper surface of the inverted conical disk body and provided with internal threads,and the inner wall of the internal thread column is provided with a suspension rubber band buckle; and rubber band holes where rubber bands penetrate are formed in the positions, located below the internal thread column, on the inverted conical disk body, the upper surfaces of the lower barbs are provided with buckles for inward binding rubber bands, the buckles on the surfaces of the lower barbsare provided with the inward binding rubber bands in a penetrating manner, the inward binding ends of the inward binding rubber bands penetrate the rubber band holes to be connected to suspension rubber band buckles, and the tray body is further provided with a detonating cord hole where a detonating cord penetrates. By means of the blast hole uncoupling energy gathering spacing device, through tray installation between plugging and charging, generation of rockets is prevented, flying stone is reduced, and the safety factor of explosion is improved.

Description

Technical field: [0001] The invention provides a blasthole uncoupled energy-gathering spacer suitable for non-coal mines and a method for using the same, which belong to the construction fields of open-air and underground blasting in non-coal mines. Background technique: [0002] The interval charging is to ensure that the ore is fully broken, and the air at the bottom of the hole is used to charge the explosives. The explosives are divided into several independent sections of grain, and each section of grain is equipped with an independent detonation and transmission system. Wired into the detonation network. When detonating, the explosion stress waves generated by several sections of explosives in the same blast hole are superimposed on each other at the moment of explosion, and the detonation gas products interact and influence each other. Finally, it can effectively improve the blasting effect and the accumulation shape of the rock slag, and reduce the peak mass of blast...

AI Technical Summary

Problems solved by technology

This kind of air spacer not only has high production cost, but also has high requirements for the safety of the cylinders of compressed gas stored

At the same time, this kind of air spacer has a low ability to control the uncoupling degree in the blast hole, and cannot achieve the best blasting effect of uncoupling charges.
