摘要
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。
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.
