浅谈聚能效应在消除残眼中的应用

The application of cumulative effect for avoiding defective hole

利用聚能效应产生的聚能流具有很大的破坏作用和穿透能力， 在岩巷掘进中可用于消除残眼， 提高炮眼利用率。

energy-cumulative flow coming from cumulative effect has tremendous action for damaging and penetrability. The defective hole in the process of head work could be avoided by using energy-cumulative flow to increase the efficiency of borehole.
