摘 要:南温河钨矿位于滇东南钨锡多金属成矿带老君山岩体西侧,矿床成因类型属层控高中温热液交代矿床,矿床工业类型为层状砂卡岩型白钨矿床[1]。经过笔者研究,层状矽卡岩型白钨矿在矿区内广泛分布,由于成矿条件差异导致白钨矿分布并不均匀,富矿段白钨矿石以团斑状、块状和网脉状产出,贫矿段以星点状产出。随着矿山向边部勘探开发,依靠原有钻探为主的勘查技术手段查明矿体资源量和实际生产量难以匹配,经过多方面摸索,矿山采用钻探指引+坑道控制的新型探矿技术手段取得较好成效。The Nanwenhe tungsten deposit is located on the west side of the Laojunshan pluton in the tungsten tin polymetallic mineralization belt in southeastern Yunnan.The genesis type of the deposit belongs to the stratigraphic controlled high temperature hydrothermal metasomatic deposit,and the industrial type of the deposit is the layered sand card type scheelite deposit.After the author's research,layered skarn type scheelite is widely distributed in the mining area.Due to differences in ore-forming conditions,the distribution of scheelite is not uniform.The scheelite in the rich ore section is produced in the form of clusters,blocks,and network veins,while the poor ore section is produced in the form of star points.With the exploration and development of the mine towards the edge,relying mainly on the original drilling exploration technology to determine the amount of ore resources and actual production is difficult to match.After multiple explorations,the new exploration technology of drilling guidance+tunnel control has achieved good results in the mine.
