Underhand cut-and-fill with cemented backfill is a high-recovery mining method, especially adoptably for those ore deposits which are rich in grade but unstable in ground conditions as the orebody and sur-rounding rocks are both concerned. However, its efficiency is rather low, its stope productivity also is quite limited and a considerable quantity of material needs to be used for supporting. By using high accesses which are staggeringly laid out between vertically adjacent suble-vels,its efficiency and...

Underhand cut-and-fill with cemented backfill is a high-recovery mining method, especially adoptably for those ore deposits which are rich in grade but unstable in ground conditions as the orebody and sur-rounding rocks are both concerned. However, its efficiency is rather low, its stope productivity also is quite limited and a considerable quantity of material needs to be used for supporting. By using high accesses which are staggeringly laid out between vertically adjacent suble-vels,its efficiency and stope productivity can be remarkably enhauced and its timber consumption to meet support requirement will be greatly reduced. In this paper, an introduction is presented about the stope layouts and mining techniques adopted in a series of field tests for this method at Lungsou mine, Jinchuan Nonferrous Metals Co. And a stability analysis for rib pillars made up of ore and cemented backfill during mining operation is also given.

下向胶结充填采矿法是一种回采率较高的方法,适合于高品位且矿体围岩均不稳固的矿床条件。然而这种方法的采矿工效低,采场生产能力小,且需消耗相当数量的支护材料。采用高进路,并使相邻分层的回采进路交错布置,可使其采矿工效及采场生产能力明显提高,且大大降低木材消耗。本文介绍了金川龙首矿试验这种高进路下向胶结充填采矿法的采场结构与回采工艺,并对胶结充填体——矿石间柱在回采过程中的稳固性进行了分析。

There are a great number of quarries in Xuzhou, in which the ecological environments are seriously destroyed by historical scattered mining operation. It is urgently necessary and feasible to do the recovery mining and land utilization for the enclosed quarries. Via three case studies, The features of recovery mining and land utilization are analyzed. Its economic benefit and social effectiveness are predicted. Recovery mining and land utilization have formed a branch of recovery development...
