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。

Abstract: According to blasting energy balance theory by Livingston, single hole series, multi hole and the same delay time, inclined bench site blasting crater experiments were done at a mine. Some blasting parameters, such as unit explosive consumption, 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.
