金堆城露天矿深孔爆破降震技术探讨

露天矿山深孔爆破具有单孔药量大,爆破频繁等特点。随着开采深度的增加,边帮的日益增高,边界的日益扩大,爆破点距村庄也越来越近,爆破震动效应控制已经成为维持矿山生产的重要课题。通过对金堆城露天爆破震动效应的因素分析,提出降震的技术措施。

Discussion on Blasting Vibration Reduction Technology of Jinduicheng Open pit Mine

Deep-hole blasting is typical of more dynamite in single-hole,frequent blasting etc.Since mining depth is increased,sides of mining are higher day by day;frontiers are extended on a daily;blasting-areas are more nearer from villages,blasting-quake effect of prevention and control already have been an important problem that maintain mining.Through analyzed factors of earthquake effects JDC,s mine blasting,technical measures for reducing earthquake are proposed.
