摘要
阐述了煎茶岭镍矿的开采技术条件、采矿方法选择、工程布置、回采工艺、充填工艺。生产实践证明,下向胶结充填采矿法在围岩极不稳固的条件下,具有充填体强度高、整体稳定性好、回采安全风险低、大幅度提高采矿回收率、降低贫化率等优点。
The mining condition, the selection of mining methods, the project arrangement, stoping and filling technology of Jianchaling Nickel Mine are expounded. The production practice proves that the underhand cemented cut-and-fill method has many advantages of high strength filling body, higher stability, lower filling risk, improving ore recovery rate greatly and reducing ore dilution rate under extremely instable surrounding rocks.
