摘要
低爆速铵油炸药是爆速在1 500~2 500 m·s~(-1)的一种铵油炸药,通过在铵油炸药中加入容重较低的惰性物质获得,具有密度低、爆速低、威力低,以及原料丰富、成本低廉、使用安全等特性,因此被广泛应用于焊接、光面爆破、预裂爆破等方面,有力推动了爆破技术的发展。本文综述了我国不同种类的低爆速铵油炸药研究现状、性能特点及应用,同时指出了现有技术存在的问题以及未来发展趋势。
The ANFO explosive with low detonation velocity between 1500~2500 m·s-1 is fabricated by adding inert substance with low bulk density to ANFO explosive,which has the characteristics of low density,low detonation velocity,low power,rich raw materials,low-cost and safety.Thus,it is widely used in welding,smooth blasting,pre-splitting blasting and so on.The ANFO explosive with low detonation velocity vigorously promotes the development of controlled blasting technology.This paper summarized the research status and the existing problems in the research of the different types of the ANFO explosive with low detonation velocity,and on the basis pointed out its future development trend.
