摘　　要：充填采矿法是一种回采率高、矿石贫化小、采矿损失率低而采矿成本比较高的采矿方法,适用于矿岩稳固性差的贵金属地下矿床以及有特殊要求的矿床开采。文中针对大岭矿矿体破碎、开采难度大的开采技术条件,详述了下向分层尾砂胶结充填采矿法的应用实践,尤其是充填系统及充填工艺。值得类似贵金属矿床开采参考。The characteristics of filling mining method are high recovery rate, low ore dilution rate and low loss factor. The method is suitable to be used in precious metal underground mining and special purpose ore mining. Based on the fractured orebody and tough mining technical conditions in Daling mine, the paper discussed the application and practice of downward delamination cemented tailings filling stoping method, especially the backfill system and technique.
