摘要
安庆铜矿高阶段大直径深孔采矿采用小段面VCR法掏槽、倒梯段侧向崩矿的爆破方式,为确定大直径深孔采矿合理的凿岩爆破参数,进行了一系列的单孔和宽孔距双孔爆破漏斗试验.本文较详细地论述了爆破漏斗试验基本过程和大直径深孔采矿凿岩爆破参数设计依据.
Anqing Copper Mine has adopted large diameter deep hole and high bench mining method, in whichthe VCR -cut within small section, upside down wedge-like, side throwing blasting pattern is used. To deter-mine the reasonable blasting parameters, serial crater tests are carried on with single borehole and two boreholeswith large spacing. This paper talks about the basic test process and the results of the experiments. A design-ing criterion is proposed for the designing of choosing parameters and blasting under large diameter, deep holemining conditions.
