在矿体可采的有效面积急剧缩小的条件下,为了维持企业活动的主要技术经济指标,需要不断改善采矿生产工艺。以开采进入最后阶段的捷格嘉尔矿为例,可以确定矿床开采后期各种因素造成的影响。捷格嘉尔矿现阶段的开采特点如下: 全部进行回采准备并最后确定合理的采矿方法。用多水平开采,是由于必须保持既定的矿石回采数量指标和质量指标。
Under the condition of sharp reduction in the effective area available for ore bodies, the continuous improvement of the mining production process is required in order to maintain the major technical and economic indicators of business activities. Taking the mining of the final phase of the Gejkar Mine as an example, we can determine the impact of various factors in the latter part of the deposit mining. The characteristics of the mining at the present stage of the Jetjar mine are as follows: Prepare all for recovery and finalize reasonable mining methods. The use of multi-level mining, is due to the need to maintain the established number of ore recovery indicators and quality indicators.
