顿河铬铁矿床,矿石储量巨大,品位高;但矿山地质条件复杂。因此,需要采用综合的方法选择和论证这种矿床的开采技术方案。目前,公司正在向地下开采过渡。“青年”矿井使用分段崩落法开采了第一批试验矿块。结果说明,由于矿体和围岩不够稳固,极不宜使用这种采矿法,需要迅速寻求有效的地下采矿法。哈萨克共和国科学院矿业研究所
Dunhe chromite deposit, huge ore reserves, high grade; but the geological conditions of the mine complex. Therefore, there is a need to adopt a comprehensive approach to selecting and demonstrating the technical solutions for this deposit. Currently, the company is transitioning to underground mining. The “Young” mines used the caving method to extract the first batch of experimental nuggets. The results indicate that due to the lack of stability of the ore body and surrounding rock, it is highly undesirable to use such a mining method and the prompt search for an effective underground mining method.
