摘　　要：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 the need of medium and long-term mining plan of Jilongshan gold mine,combined with the engineering geologic condition of the 35# stope in-130m level,the design of medium-long hole drilling and blasting of 1~14 row,15~51 row hole for ore caving and the hole for-117 m trough cutting was made,and the blasting effect was evaluated also.The result indicated that the design of controlled stope blasting with medium-long hole is successful in Jilongshan gold mine,the fragment size of caved ore mostly is 0.3m×0.3m,the explosive specific charge of blasting is decreased obviously,good technical-economic effect has been got.
