鸡冠嘴金铜矿中深孔凿岩爆破参数的优化试验

Sdutdy on optimization of blasting parameter for middle depth hole explosion in Jiguanshan Glod Mine

通过爆破漏斗、斜面台阶、不等孔距爆破试验以及多排同段起爆试验,在综合统计并分析计算各种试验数据的基础上,对鸡冠嘴金铜矿的中深孔凿岩爆破孔底距、最小抵抗线、单位炸药消耗量等参数进行了优化,并在实际生产中推广应用,取得了较好的技术经济效果。

Based on comprehensiveness analysis and calculation on data from blasting experiments including blasting crater, incline bench, different distance of hole, initiation in multi-row and same stage, optimization of blasting parameters such as distance of hole bottom, minimum burden, explosive consumption an unit etc. for middle depth hole explosion was made. The parameters optimized were applied in actual operation and good results was got.
