逐孔起爆技术及其应用

The application of hole by hole initiation technique

随着高精度毫秒导爆管雷管的出现,逐孔起爆技术得以实现。文中介绍了以降低爆破振动和破碎块度为目的的逐孔起爆技术,分析了逐孔起爆机理、起爆方式、网络设计及合理微差间隔时间的确定方法,并将该技术应用于露天矿山台阶爆破中,取得了预期的效果。最后探讨了该技术的应用前景和进一步的研究方向,为逐孔起爆技术在我国露天矿山的进一步推广应用提供了理论指导。

With the appearance of high-precision millisecond nonel detonator, the technique of hole-by-hole is developed. The paper introduces the hole-by-hole technique aiming at reducing blasting vibration and the size of rock broken, analyzes its mechanism, igniting mod, network design and the determination method of sound millisecond delay interval. The method has been applied to bench blasting of open mine and the anticipative effect has been made in the paper. In addition, the author discusses the application prospect and further research orientation, which will offer theoretical guide for further generalization and application of the method in domestic open mines.
