摘要
岿美山钨矿目前开采的矿脉产状变化大,矿脉变细、变薄甚至极薄较为普遍,部分矿脉按浅孔留矿法、崩落法等传统方法开采,技术经济指标较差。采用削壁充填法,采场底部结构为无底柱人工假漏斗出矿的形式,可提高采矿回收率,降低矿石的贫化率,技术经济指标较优。
The tungsten resources in kuimeishan mine have dwindled due to decades of mining. Thin tungsten vein is a common problem in the current mining process. Traditional mining methods, including shallow hole shrinkage method and caving mining will inevitably lead to low technical and economic indicators. A new method, composed of waste- lifting shrinkage stoping method and pillarless shallow hole Stoping method is applied to improve the mining recovery rate and reduce the dilution rate.
