摘要
介绍了BJK气体间隔器在某露天矿台阶深孔富水孔炮孔中的试验研究,采用底部间隔装药技术,取得了较佳的技术经济效果,既降低了爆破成本,也改善了爆破质量。
The paper introduce the research and study of P, JK gas spacer in a blast hole of deep rich water hole in an openpit mine step. The adoption of bottom interval drug charging technology achieves good technical and economic effect. On the one hand it reduce the blast costs, on the other hand, it improves the blast quality.
