| 摘 要： | 本文通过对球状和柱状药包爆破时不同崩矿方式的作用比较,指出地下大直径深孔采矿法采用柱状药包侧向梯段崩矿能获得更大的采场生产能力。采用这种崩矿方式可以使用低威力炸药,也可适当地充大孔网参数。最后还举出了矿山实际应用的例子。

| Abstract: | Comparing the effect of spherical and column cartridges on functions of different ore caving methods, this paper points out that lateral stepped ore caving with column charges in large-diameter longhole mining not only affords the stope greater production capacity,but also makes it possible to use low-strength explosive and properly increase blasthole patters. Finally, a few application cases are cited. |
