摘要
为了安全地回收获各琦铜矿1 690m中段各个采场顶柱,并为其它采场顶柱回收提供经验,选定1 690m中段901采场作为试验采场,并采用无底柱分段崩落法对其顶柱进行回收。实践证明,无底柱分段崩落法能够安全、有效地回收顶柱,并且损失率和贫化率等各项指标均达到设计要求,并为回收其他类似采场顶柱提供借鉴。
In order to safely recover top pillars of each stope at the depth ot 1690m in kiuogeql Copper Mine, and provide experience for pillar recovery of other stope, 901 Stope at the depth of 1690 m is selected as experimental stope and no-pillar sublevel caving is used to recover its top pillar. The practice proved that this method can safely and effectively recover the top pillar; the loss rate, dilution rate and other indicators can meet the design requirements, which provide a reference in recovering of other similar top pillars.
