岩巷掘进中深孔爆破技术可以减少辅助作业时间,提高单班循环进尺和巷道掘进速度。通过在邢东矿大断面岩巷施工中采用复式双楔形掏槽技术,提高了炮眼利用率和岩巷掘进速度,降低了材料消耗,缓解了该矿采掘衔接紧张的局面,取得了良好的效果。

英文摘要：

The deep hole blasting in roadway excavation can reduce time of auxiliary operation and improve single-circulating footage.By using the double wedge cutting in the rock roadway construction at Xingdong Mine,the embrasure utilization ratio have a good advance and the construction schedule is greatly improved and material consumption and staffing dropped,the promotion of this technology has acquired good results with easing the tense situation in the mine extraction of convergence.
