摘要
大湖金矿矿体形态不规整,连续性差,尖灭再现,分支复合较多,厚度较小且很不稳定。矿体倾角大部分为33°~40°,部分矿岩稳固性较差,局部品位变化较大。通过多种采矿方法的技术经济分析,认为采用锚杆护顶的全面采矿法较为合理。
The ore bodies in Dahu Gold Mine are irregular and narrow with poor continuity which are branched and combined.The angles of dip are from 30°to 40°,part of ore rock are unstable.Local grade of metal varies largly.Technological and economical analyses show that the breast stoping with roof bolting is more reasonable than others.
