摘要(Abstract):

为防止露天矿边坡过爆和减小爆破振动对边坡的破坏,对边坡处炸药单耗、起爆方式、延时等因素,结合爆破反馈的数据进行了分析,提出了对生产爆破、缓冲爆破和预裂爆破各参数具有操作性的建议。
For avoiding over-blasting to the slope and reducing blasting vibration to its damage in the open-pit mine,factors such as unit consumption of explosives,initiation mode and delay time etc were analyzed by combined with blasting feedback data,and suggestions which can be worked were provided about parameters of production blasting,buffer blasting and presplit blasting.
