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.
