摘　　要：尽管大吉山钨多金属矿山的发现已有上百年的历史,确定为超大型的钨铌钽铍多金属矿床,但受历史原因和探矿技术条件的限制,勘探深度主要在467 m中段以上标高,探究该矿的资源潜力有较大的现实意义。近年进行的深部找矿项目中,在北组104线深部278 m标高处和267 m标高处分别揭露23号、24号脉组,在南组矿带267 m中段,钻孔揭露工业矿脉17条次,累计真厚度3.53 m,新增了大量钨多金属资源储量。研究总结了该矿床历史深部找矿成果,探讨了找矿新进展和资源潜力,为下一步资源潜力找矿明确了方向。As a super-large tungsten niobium tantalum beryllium polymetallic deposit,Dajishan Tungsten Polymetallic Mine has a mining history of more than 100 years.Limited by historical reasons and technical prospecting conditions,the exploration depth was above the mid-section elevation of 467 m.Thus,it is of great practical significance to explore the resource potential of this mine.In the deep prospecting projects carried out in recent years,No.23 and No.24 vein groups were exposed at the 278 m elevation and 267 m elevation at the depth of the 104th line of the North Formation,respectively.In the 267 m middle section of the South Formation ore belt,17 industrial veins were exposed.The cumulative true thickness is 3.53 m,and a large amount of tungsten polymetallic resources have been added.On the basis of summarizing the deep prospecting achievements,new prospecting progress and resource potential,we clarify the direction for the next potential resource prospecting.
