Abstract

Large-scale mining methods are taking over the leading role in exploitation of low-grade and deep mineral deposits considering its high productivity, low cost, and satisfying ore recovery and ore dilution. In order to improve properties of existing block and sublevel caving methods, researches were carried out in laboratory conditions on physical model of similarity. Results of the research, the determination of optimal parameters and indicators for the new variant of the caving mining method is discussed in this paper. Experiments were based on ore drawing for the case with two and three one-sided lateral loading chambers and they were performed in order to determine the best combination between variable parameters of block width and spacing between loading chambers that would give the most optimal results for ore recovery and ore dilution.

侧向加载半水平诱导崩落法主要参数的确定

摘要

规模化开采方式以其产能高、成本低、满足矿石回收率和矿石稀释度等优势，在低品位、深层矿床的开采中占据主导地位。为了改善现有块体和分段崩落方法的性能，在实验室条件下对相似性物理模型进行了研究。本文讨论了研究结果、确定崩落采矿方法新变体的最佳参数和指标。实验基于具有两个和三个单侧横向装载室的情况下的矿石提取，并且进行这些实验以确定块宽度和装载室之间的间距的可变参数之间的最佳组合，这将为矿石提供最佳结果回收和矿石稀释。
