光面爆破是现代控制爆破中运用得较成功的并日益推广的一项先进爆破技术。与普通爆破法相比较,光面爆破有着许多突出的优点,但是光面爆破作用机理的研究仍不够充分,各种参数的确定,至今还缺少成熟而又简单实用的理论计算法。本文就光面爆破中周边光爆眼不偶合系数的确定进行探讨。一、理论依据1.光面裂隙形成条件光面爆破效果取决于贯穿周边光爆眼轴心面之光面裂隙的形成。普通爆破法中,炮眼围岩在爆炸冲击波和爆轰气体的作用下一般都会产生一定宽度的压缩粉碎区、环状裂隙和放射状径向裂隙。要实现光面爆破,保证光面裂隙
Smooth blasting is an advanced blasting technique that has been used successfully in modern controlled blasting and is being promoted more and more. Compared with ordinary blasting, smooth blasting has many outstanding advantages. However, the research on the mechanism of smooth blasting is still not enough. The determination of various parameters still lacks the mature and simple theoretical calculation method. This paper discusses the determination of the non-coupling coefficient of the peripheral light burst in smooth blasting. First, the theoretical basis 1. Smooth fissure formation conditions Smooth blasting depends on the surrounding light burst the central axis of the smooth surface of the formation of cracks. Ordinary blasting method, the blasthole rock in the blast shock wave and detonation gas will generally have a certain width of the crushing zone, annular cracks and radial radial cracks. To achieve smooth blasting, to ensure smooth cracks
