提升供矿品位的长效方法研究——以甘肃某矿为例

Research on the Long-term Method for Improving the Grade of Ore Supply--taking A Mine in Gansu as An Example

2021年3月以来,甘肃某矿供矿品位持续降低,矿山通过加大采场崩矿量、调整配矿比例等多种措施来缓解困境,但效果不佳。笔者在对矿山保有资源储量和开采现状进行调查的基础上,分析了供矿品位降低的主要原因,提出矿山提升供矿品位长效机制的方法和措施,取得较为显著的效果,对其他矿山的采出矿品位管理也有一定的借鉴和指导意义。

Since March 2021,the ore supply grade of a mine in Gansu has continued to decrease.The mine has taken various measures such as increasing the stope collapse and adjusting the proportion of ore blending to alleviate the predicament,but the effect is not good.Based on the investigation of the mine's retained resource reserves and mining status,the author analyzes the main reasons for the reduction of the supply grade,and proposes methods and measures for the mine to improve the long-term mechanism of the supply grade,which has achieved remarkable results.Mining grade management also has certain reference and guiding significance.
