黑岱沟露天煤矿预裂爆破优化方案设计与实施

摘要

对黑岱沟露天煤矿预裂爆破炮孔布置参数、装药结构、起爆网络的进行设计,确定合适的孔网参数、前排抵抗线和微差时间等因素,在确保爆破质量的前提下有效降低对边坡的震动,达到提升预裂爆破质量的目的。%hrough Heidaigou open - pit coal mine provide theoretical support pre - splitting blast blast hole layout parameters, charge structure, detonating network design and optimization, reasonably determine the appropriate pore network parameters, front resistance line and millisecond time. And factors, thus realizing the ensure blasting quality premise effectively reduce the vi- bration of the slope presplit blasting, improve the quality of purpose.
