叙述了一种由粒状硝镀和橡胶组成的新型低冲击能炸药─—ANRUB。现有的低冲击能炸药是通过大幅度降低炸药密度和/或利用稀释刘来降低冲击能,因此减小了体积能量。本文讨论的方法通过放慢炸药反应速率来降低冲击能量,同时保持与ANFO相近的总能量。本文讨论了ANRUB的发展,包括最初的水下试验到大规模的现场试用。在每一试验阶段同时测量ANRUB和ANFO,以确定冲击能的降低和随之而来的鼓胀能增加。测定参数包括水市冲击能、鼓胀能、爆速(VOD)、振动强度和鼓胀速度。ANRUB具有改进最终边界和生产爆破的潜力。低的冲击能特征对最终边界爆破来说是所希望的,而高的鼓胀分量很适于生产爆破。
A new type of low impact explosive consisting of granular nitrate and rubber is described - ANRUB. Existing low impact explosives reduce the impact energy by drastically reducing the explosive density and / or using dilute Liu, thus reducing the volumetric energy. The method discussed in this article reduces the impact energy by slowing the reaction rate of explosives while maintaining the total energy that is similar to ANFO. This article discusses the evolution of ANRUB, from initial underwater testing to large-scale field trials. Simultaneous measurement of ANRUB and ANFO at each test stage was performed to determine the reduction of impact energy and the consequent increase in bulge. Measured parameters include water impact energy, bulging energy, detonation velocity (VOD), vibration intensity and bulging velocity. ANRUB has the potential to improve the final boundaries and production blasting. The low impact energy characteristics are desirable for the final boundary blasting, while the high bulge component is suitable for producing blasting.
