摘　　要：铜绿山铜铁矿采用中深孔爆破落矿,为了得到铜绿山高阶段采场的中深孔爆破参数,本文基于利文斯顿爆破漏斗理论,推导了适用于中深孔爆破的柱状药包理论公式,并在一定的矿岩和炸药性能条件下进行了一系列爆破漏斗试验。结果表明:药包的最佳中心埋深为0.42 m,最佳爆破漏斗体积为0.016 m~3,最佳爆破漏斗半径为0.45 m,最小抵抗为0.79 m;铜绿山铜铁矿同段爆破漏斗试验最佳孔底距为0.8~0.9 m;基于柱状药包爆破漏斗推导公式,得到现场中深孔爆破的最佳回采炮孔排距为1.62 m,最佳孔底距为1.65~1.85 m。In order to obtain the parameters of medium and long hole blasting in Tonglvsshan Copper Iron mine,based on Livingston blasting funnel theory,this paper deduces the theoretical formula of cylindrical charge suitable for medium and long hole blasting,and carries out a series of blasting funnel tests under certain conditions of ore,rock and explosive properties.The results show that the best central depth of charge is 0.42 m,the best volume of blasting funnel is 0.016 m~3,the best radius of blasting funnel is 0.45 m,and the minimum resistance is 0.79 m.The optimum hole base distance of Tonglvshan Copper Iron Mine is 0.8~0.9 m in the same section blasting funnel test.Based on the derivation formula of cylindrical charge blasting funnel,the optimal hole row spacing and hole bottom spacing are 1.62 m and 1.65~1.85 m respectively.
