深井硬岩巷道聚能爆破技术的应用实践
|
摘要
以12513Ⅱ工作面轨道巷为工程实例,为提高深井硬岩巷道掘进效率,应用多向聚能爆破技术;以爆破产生的冲击能量波与爆生气体破岩,相比普通爆破,具有多方向控制爆破优点;多向聚能爆破在该巷道掘进中应用,加快了巷道掘进进尺,提高了矿井的经济效益。
Taking the track roadway of 12513Ⅱ working face as an engineering example,in order to improve the excavation efficiency of hard rock roadway in deep mine,the multi-directional energy-accumulating blasting technology is applied.Compared with ordinary blasting,the multi-directional controlled blasting has the advantages of breaking rock with shock energy wave and explosive gas generated by blasting.The application of multi-directional energy-accumulating blasting in the roadway excavation speeds up the roadway excavation footage and improves the economic benefits of the mine.
