| 摘 要： | 广东韶关凡口铅锌矿狮岭南区段的开拓工程已延伸至-550m中段，矿体呈现尖灭趋势。为查明深部区域地层矿化特征、构造控矿特点，并指导深部寻找盲矿体，通过收集分析中上部各中段地质资料，并与地质勘查资料对比，利用坑道设计并施工了9个孔深300 m左右的坑内探矿钻孔，进一步查明了狮岭南深部地质特征，并在F3断裂下盘探获多条盲矿体。F3断裂既是导矿构造，也是重要控矿构造，其下盘至F203断裂之间的夹持带为狮岭南深部有利成矿空间

| Abstract: | The development project of South Shiling section of Fankou lead-zinc mine in Guangdong Province has been extended to -550 m middle section, and the orebodies show a pinch-out trend. In order to determine the characteristics of stratum mineralization and structural ore-controlling in deep region and guide the deep exploration for blind ore bodies, nine boreholes at a depth of about 300 m were designed and constructed by means of tunnels through collecting and analyzing the geological data of upper and middle sections and comparing with the geological prospecting data. The deep geological characteristics of South Shiling were further identified, and several blind ore bodies were discovered at the footwall of F3 fault. The F3 fault is not only an ore-conduit structure, but also an important ore-controlling structure. The holding zone between its footwall and F203 fault is a favorable metallogenic space in the deep of South Shiling. |
