为满足鸡笼山金矿中长期开采规划的要求,结合-130m35#采场的工程地质概况,分别对孔-117m切割槽,1～14排、15～51排落矿中深孔进行了凿岩爆破设计,同时评估了爆破效果。结果表明,鸡笼山金矿中深孔控制爆破设计是成功的,爆破矿石块度大多为0.3m×0.3m,炸药消耗也明显下降,取得了良好的技术经济效果。
In order to meet the requirements of medium and long-term mining planning of Jilongshan Gold Mine, combined with the engineering geology of -130m35 # stope, deep holes were drilled in hole -117m, 1 ~ 14 and 15 ~ 51 respectively Rock blasting design, while evaluating the blasting effect. The results show that the design of deep hole controlled blasting in Jijinshan Gold Mine is successful. The block size of blasting ore is mostly 0.3m × 0.3m, the explosive consumption also drops obviously, and a good technical and economical effect has been achieved.
