摘要
根据胡家峪铜矿的有底柱崩落法实践 ,探讨降低矿石损失和贫化率的有效途径。结果表明 ,基础资料准确、高质量采切工程、严格放矿管理和合理的开采顺序是减少矿石损失和贫化的有力保障。
The measures for reduction of oes losing and degrading are described based on the sublevel caving practice in Hujiayu Copper Mine. The precise foundation information, high quality caving and mining engineering, strict drawing management and appropriate caving sequence are the effective ways for the prevention of ore losing and degrading.
