浅析降低无底柱分段崩落法损失贫化的最新研究状况

The simple analysis about the new study situation of reduce dilution and losing of ore about non-pillar sublevel caving method

随着无底柱分段崩落法应用范围不断的扩大,其损失贫化大的缺点也愈加明显,因此为尽可能的降低损失,学者们对其做了许多的研究,包括结构参数、放矿方式、爆破方式、覆岩、松散介质等一系列的研究,取得了一定的成果,但还存在着许多的难题有待解决。

With the rang continuous enlarge of non-pillar sublevel caving method, it＇s drawback more and more clear about dilution and losing of ore. So it is important to slow down the dilution and losing of ore, many scholars have done many researches about it. Such as the study of ore-body parameters, ore-drawing-way, blasting-way, covering layer, loose medium and so on. These researches have got many achievements, but they also have many problems that need our solution.
