Safety Assessment of Blasting Shock Wave of Linear Shaped Charge using Emulsion Explosive

Abstract

In the open-pit mine, the on-site mixed emulsion explosives are used to fill the energy collecting device, and the linear energy gathering and cleaving technology is used to enhance the shaped energy jet and improve the blasting efficiency. Analyse its application safety after performing shockwave safety testing. The results show that after the optimized energy-concentrating device is filled with 0.5 Kg of emulsion explosive, the power is increased to achieve the explosive blasting effect. The generation and transmission of harmful gases are greatly reduced, which is an effective way to guarantee the effect of blasting and the safety of production.
