最近8～10年来在乌拉尔的一些地下金属矿山加速采用水平分层水力充填采矿方法。这种方法运用的情况表明,矿石数量和质量损失的总水平并没有降低。原因是所采用的层间垫板和水力充填隔墙的结构不完善引起富集的粉矿发生损失和充填材料使矿石贫化。乌拉尔制铜工业科学研究设计院完成了一项综合研究,其成果是创造了结构新颖的层间 Some underground metal mines in the Urals in the recent eight to 10 years have accelerated the adoption of horizontal stratified hydrofilling mining methods. The application of this method shows that the overall level of ore quantity and quality loss has not decreased. The reason is that the imperfect structure of the inter-layer dunnage and hydraulic-filled partition wall used causes the loss of enriched fines and the filling material depletes the ore. Ural Copper Industrial Science Research and Design Institute completed a comprehensive study, the result is to create a novel structure between the layers
