炸药性能与岩石爆破作用的相关性

The Dependence of Rock Blasting Effects on Explosive Properties

本文给出了孔壁压力随时间变化的力学模型和数值方法,分析了炸药性能与岩石爆破作用的相关性。从理论上证明了低速炸药宜用于抛掷为主要目的的工程爆破,高速炸药宜用于破碎为主要目的的工程爆破。

In this paper a mechanical model and numerical techniques for the variations of Pressures on hole walls with time were developed, and the dependence of rock blasting effects on explosive properties was analyzed. It was theoretically proved that the explosives with low detonation velocities are fitted for blasting projects to throw, and those with high detonation velocities are fitted for blasting jobs to crack.
