甘肃某金矿矿床工业指标论证

Industrial Index Demonstration of a Gold Deposit in Gansu Province

矿床工业指标是矿床工业价值评价、矿体圈定、矿产资源储量估算的标准和依据。以甘肃某金矿为例,在综合分析矿床地质及开采技术条件的基础上,运用类比法和图解法确定边界品位,参照盈亏平衡原则论证确定最低工业品位,以此为基础拟定工业指标方案,对矿体进行试圈试算。再结合当前黄金市场价格条件,采用地质方案法对3套工业指标进行论证分析,最终选择出矿床的工业指标,以此为依据进行矿体圈定和储量估算,对提高矿山资源利用率及企业经济效益起到积极的作用。

The industrial index of the deposit is the standard and basis for the evaluation of the industrial value of the deposit,the delineation of the ore body and the estimation of the mineral resource reserves.Taking a gold mine in Gansu Province as an example,based on the comprehensive analysis of the geological and mining technical conditions of the deposit,the boundary grade is determined by analogy method and graphic method,and the minimum industrial grade is determined by the principle of profit and loss balance.Based on this,the industrial index scheme is drawn up,and the ore body is tested and calculated.Combined with the current gold market price conditions,the geological scheme method is used to demonstrate and analyze the three sets of industrial indicators,and finally the industrial indicators of the deposit are selected.Based on this,the ore body delineation and reserve estimation are carried out,which plays a positive role in improving the resource utilization rate and economic benefits of the mine.
