| 摘 要： | 为提高硬岩巷道掘进速度,对爆破参数进行了优化设计。通过现场试验,结果表明:优化后的爆破参数大大提高了硬岩施工速度,月进尺由原来的42 m提高到目前的86 m。掏槽眼采用垂直楔形辅助掏槽方式,易于操作,便于掌握,实际应用效果好。该爆破工艺高效、安全、可操作性强,对类似硬岩中深孔爆破具有指导意义。

| Abstract: | In order to improve the excavation velocity of hard rock drift,the blasting parameters was designed and optimized.By the site experiment,the results show that the excavation velocity of hard rock drift is greatly improved,and the drill footage per month is increased to current 86 metres from 42 metres.The cutting method of perpendicularity and wedge-shape is applied,which is easily operated and grasped,and the actual effect is good.This blasting technology is high efficient,safety and enough of maneuverability,which offers a guidance for the similar engineering. |
