摘要：

为解决河南金源黄金矿业有限责任公司祈雨沟金矿区角砾岩体厚大矿体采矿方法及矿柱回收问题, 在2 # 角砾岩体进行了中深孔采矿工业试验, 两次爆破成功, 落矿28 600t 。从试验结果来看,中深孔采矿不失为回采低品位、大规模的角砾岩体的一种高效

关键词: 角砾岩, 中深孔, 试验研究

Abstract:

To resolve the problem of mining in large thick ore body and recovery of ore pillar in Qiyugou mineral area ,two successful experiment s of medium-depth-hole mining have been made in 28 600 tons. From the result ,medium-depth-hole mining is a high effective method in mining low grade and t remendous breccia mass.

Key words: breccia mass, medium-depth-hole, experimentand study
