| 摘 要： | 根据永平铜矿实际爆破情况,运用爆轰理论,对露天矿垂直与倾斜两种中深孔的爆破特征进行了分析.分析从底盘抵抗线、孔网参数、大块与粮底、钻孔效率与作业成本和爆破地震效应五个方面入手,阐述了两种不同类型钻孔的不同爆破作用机制及其爆玻效果,肯定了倾斜孔在露天台阶爆破中所具有的独特优越性.

| Abstract: | According to the specific situation of blasting in Yougping copper mine, the author uses the detonation theory to analyze the characteristics of both vertical and in-clined moderate Longhole blasting in open pit mines. Beginning by the analysis of toe bur-den, hole-pattern parameters, Large fragment productivity, toe rock drilling efficiency, operating cost and seismic effect of blasting the author describes the different blasting mechanism and results about two types of drilling holes, and confirms a unique superiority of inclined holes about the bench blasting in open pit mines. |
