炮孔因素对露天台阶爆破效果的影响分析

Analysis on the Influence of Borehole Factors on Open Bench Blasting Effect

钻孔爆破中,与炮孔有关的参数是影响爆破效果的最重要因素之一。主要分析了炮孔倾斜度、炮孔直径、超深和堵塞长度、孔距和排距、最小抵抗线等因素对爆破效果的影响,这对台阶爆破设计有一定的参考价值。

Borehole is one of the key factors which influence blasting effect in the borehole blasting. Gradient, diameter, extra-deep, stem length, hole space, row space and minimum resist line of borehole are analyzed in this paper. This may be reference to design of bench blasting.
