摘要
通过对掘进炮孔深度的研究分析,在矿山中如何提高一次循环掘进深度,降低爆破器材成本,充分发挥凿岩设备的优势,确定了最优炮孔深度,并取得了良好的效果。探索今后手持式凿岩设备条件下深孔作用的应用前景。
The optimum depth of blasting hole is determined following the principles of increasing digging depth within one cycle, decreasing cost of blasting materials and making full use of equipment capability. The future of using hand-held type hammer drill to make deep hole is explained.
