摘要: 为科学判定某矿东帮矿体的资源开发价值,支撑矿业工程开采规划,通过现场钻孔 取心与室内多指标试验,系统研究矿体物理化学性质。针对选矿台效受矿体普氏硬度、Mo 品位及 黄铁矿含量联合影响的问题,采用层次分析法(AHP)构建三级评价体系,量化各因素对矿体开发 价值的综合作用。评价结果显示,Mo 品位对综合得分贡献最大(权重 0.639),是决定矿体经济价值 的核心指标;黄铁矿含量(权重 0.250)与普氏硬度(权重 0.111)次之,且二者过高均不利于选矿提质 增效。钻孔综合评分表明,ZK1-1 孔 600.00~610.00 m、ZK2-2 孔 620.00~630.00 m 周边矿体得分较 高,可作为优先开采区域,以提升资源利用效率;低得分区间需结合地质补勘,进一步评估其经济 开发可行性。

Abstract: In order to scientifically determine the resource development value of the eastern ore body of a mine and support the mining planning of mining engineering,the physical and chemical properties of the ore body are systematically studied through on-site drilling coring and indoor multi-index test. Aiming at the problem that the effect of mineral processing is affected by the combination of ore body's hardness, Mo grade and pyrite content,the analytic hierarchy process (AHP) is used to construct a three-level evalu‐ ation system to quantify the comprehensive effect of various factors on the development value of ore body. The evaluation results show that Mo grade contributes the most to the comprehensive score (weight 0.639), which is the core index to determine the economic value of the ore body. The pyrite content (weight 0.250) and the Platts hardness (weight 0.111) are second,and both too high are not conducive to improving the quality and efficiency of mineral processing. The comprehensive score of drilling shows that the ore bodies around ZK1-1 hole 600.00~610.00 m and ZK2-2 hole 620.00~630.00 m have higher scores,which can be used as priority mining areas to improve resource utilization efficiency. The low score interval needs to be combined with geological survey to further evaluate its economic development feasibility.
