摘　　要：沃溪金锑钨矿属中低温热液石英脉型矿床,矿体分布严格受构造控制。通过对深部构造、矿体特征和控矿规律综合分析,认为十六棚公矿段深部V3、V8脉主要受沃溪西向斜和沃溪大断层控制,矿体主要赋存于西向斜层间滑脱带中,且近似平行,研究表明西向斜属斜歪倾伏褶皱,且由NE向NEE侧伏,轴面倾向NW-NNW,倾角在25°~60°,通过井下揭露的V3、V8脉确定不同深度的褶皱枢纽,在此基础上建立了十六棚公矿段控矿褶皱轴面模型,为矿山进一步找矿和综合研究提供了理论依据。The Woxi gold-antimony-tungsten deposit belongs to the medium low-temperature hydrothermal quartz-vein-type de-posit,and the distribution of the ore body is strictly controlled by the structure.Through comprehensive analysis of deep structures,ore body characteristics,and ore control laws,it is believed that the deep V3 and V8 veins in the Shiliupeng Gong ore section are mainly controlled by the Woxi West syncline and the Woxi large fault.The ore body mainly occurs in the interlayer slip zone of the West syncline and is approximately parallel.Research has shown that the westward inclined fold belongs to the oblique oblique fold,and it slopes from NE to NEE,with an axial plane inclined to-wards NW-NNW and an inclination angle of 25°-60°.Based on the V3 and V8 veins exposed underground,fold hubs at different depths were determined.On this basis,an axial model of the ore controlling folds in the 16th Penggou mining section was estab-lished,providing a theoretical basis for further exploration and comprehensive research in the mine.
