摘要
桦树沟铜矿床铜矿体呈隐伏、半隐伏状态赋存于铁矿体下部,构成上铁下铜格局。主要矿石类型有含铁碧玉岩型和蚀变千枚岩型,区内岩石普遍发生浅变质作用,主要表现为重结晶作用。桦树沟铜矿在2850m水平以下均采用中深孔落矿,在中深孔落矿的过程中存在着大块多、矿石贫化大以及一部分矿石难以用中深孔回采等问题。
The copper ore body of the Huashugou copper deposit is invisible and semi-con- cealed state occurring in lower part of ore body, which forms the pattern of lower copper upper iron. The main ore types are iron-containing jasperite and altered phyllite. The rocks in the area are mainly metamorphic, mainly characterized by recrystallization. In the case below 2850m, Huashugou copper deposit is used for deep-hole mining. In the course of deep-hole mining, there are many problems such as large chunks, large ore depletion and large part of the ore which cannot be used.
