摘要
根据大坪金矿矿床的赋存条件和资源状况,结合矿山开采技术条件采用无底柱浅孔留矿采矿法,解决了矿山薄矿体开采矿石的贫化和损失等问题,取得了一定的经济效益。实践证明是一种适合我矿特点的有效方法。
According to the occurrence conditions and resources in Daping gold deposit, combined with the mining techni- cal conditions , non-pillar shallow hole shrinkage stoping method is used to solve ore dilution and loss problems in thin ore body mining, which is proved to be a effective method suiting for the specific ore body features.
