摘要
从炮眼位置、掏槽方式、起爆方式分析了煤矿掘进中深孔爆破技术的应用方法,探讨了中深孔爆破技术的拒爆原因及解决措施,具体措施包括明确拒爆原因,重新连接线路进行二次爆破等。实践得出,工作人员仍需不断总结煤矿爆破技术经验才能在实际工作中提高煤矿掘进效率,保证施工质量。
From the hole position, cutting method, initiation method of deep hole blasting technology in coal mine tunneling, discusses the causes and solutions to burst in deep hole blasting technology, including clear misfire reasons,re- connection line for two times. The blasting practice, the staff still need to constantly sum up the experience of coal mine blasting technology in order to improve the driving efficiency of coal mine in practical work to ensure the quality of construction.
