摘　　要：控制矿岩爆破装药单耗是矿山生产中的一项重要内容。本文通过对紫金山金铜矿地下采场生产现状进行分析,结合炸药破岩理论,对现有爆破方案进行优化。通过理论研究和公式推导,得出不改变现有炮孔直径和药卷直径,采用轴向空气间隔装药结构可以降低爆破单耗,并通过数值模拟验证优化后的装药结构破岩效果可达到预期。Control of ore - bearing rock blasting charge unit consumption is an important content of mine production. The purpose of this paper is to optimize the existing blasting scheme through the analysis of the production status of the underground stope in Zijinshan, combi- ning with the theory of explosive rock fragmentation. By theoretical analysis and formula derivation, using the axial air interval charging structure can reduce the blasting unit consumption, without changing the existing hole diameter and charge roll diameter, and verify the op- timized charge structure rock can achieve expected effect by using numerical simulation.
