摘要
为提高岩巷掘进速度,本文结合小峪矿南部运输大巷地质条件,采用中深孔“三小”一次爆破技术,成功的实现了三小条件下的全断面中深孔发爆器一次爆破。经过现场试验和指导,三小条件下中深孔一次爆破技术逐渐地被现场工人所接受,并熟练掌握,有利于促进矿井的安全生产。
In order to increase the speed of rock tunnel excavation,this article combines the geological conditions of the southern transportation roadway of Xiaoyu Mine and adopts the“three small”one-time blasting technology for medium and deep holes,and successfully realizes the full-section medium and deep hole blaster under the conditions of three small holes.One blast.After on-site testing and guidance,the one-time blasting technology of medium and deep holes under three small conditions is gradually accepted and mastered by on-site workers,which is beneficial to promote the safe production of the mine.
