摘要
利用炮孔复合装药进行了爆破试验。通过测定质点峰值振速,探索不同方向上地震波强度的差别。同时,与常规装药的爆破震动峰值振速进行了对比。试验结果表明,炮孔复合装药的爆轰波主传播方向上地震波强度最大,其反方向上地震波强度最小;与常规装药结构相比,炮孔复合装药爆轰波主传播方向的反方向上的爆破地震波强度降低30%以上。
The blasting tests were carried out with a compound charge in a blasthole.The difference between blasting vibration strengths in different directions where the detonation wave propagates was studied through measuring the peak particle vibration velocities.At the same time,the comparison between the vibration velocities from a compound charge and the common charge respectively was made.The test results indicate that the maximal blasting vibration strength occurs in the dominant propagating direction of detonation wave and the blasting vibration strength is minimal in the opposite direction,with a decrease of over 30% as compared with the strength of blasting vibration from the conventional charge.
