长、短分期开采在甲玛铜多金属矿设计中的应用

分期开采是金属矿山露天开采中一种机动灵活的开采方式,可有效地推迟剥离高峰,减少基建投资,且具有规避投资风险的作用。以地处高原的甲玛铜多金属矿露天开采为工程背景,详细介绍了长、短分期开采在二期扩建工程角岩、矽卡岩2个露天采场设计中的应用过程。长、短分期开采在扩建工程中的灵活运用,使矿产资源开发更为经济合理。

Application of phased mining in the design of Jiama polymetallic mine

Phased mining is a flexible mining method applied in open mining of metallic mines .It can effectively delay stripping peak ,reduce infrastructure investment and evade investment risk .The paper takes Jiama polymetallic mine for engineering background ,in detail introduces the application of long-term and short-term phased mining in the design of the second phase of the expansion projects of hornstone and skarn open -mining mines .The flexible use of long-term and short-term phased mining in expansion projects makes the exploitation of resources more economical and reasonable .
