摘　　要：根据利文斯顿爆破能量平衡准则,在某矿山进行了单孔系列、多孔同段和斜面台阶现场爆破漏斗试验,确定该矿中深孔分段矿房阶段嗣后充填法开采的炸药单耗、最小抵抗线、孔底距、孔间距等爆破参数,为工业试验及后续生产提供设计依据。According to blasting energy balance and the same delay time, inclined bench site blasting ting parameters, such as unit explosive consumption, theory by Livingston, single hole series, mulh hole crater experiments were done at a mine. Some bias- burden in directional blasting, bottom hole distance of medium-deep hole sub room stage delayed filling method mining of this iron ore, were confirmed. It provides design basis for industrial tests and subsequent productivity.
