万古矿区作为湘东北金成矿带上重要的矿床，大小不一的断裂与断层严格控制着矿区
各条矿脉的矿体形态和赋存部位。以往对该矿区断裂的研究多集中在北西向的容矿断层，而对该矿
区中作为控矿构造的北东向 F8断层研究不足。为进一步探究 F8断层对矿区成矿构造的影响，从井
下-380 m中段工程中的不明断层出发，通过几何模型和资料比对等方法，验证该断层为地表F8断层
在地下部分的延伸。研究表明，F8断层可能为右行逆断层，并与其周边同北东走向的断层同期形成，
共同充当该矿区矿脉形成的控矿构造。上盘牵引褶皱受到断层构造影响，常常能形成节理脉。研究
对提高矿区资源储量，提升找矿效率有较大帮助。
Wangu mining area is an important deposit in the gold metallogenic belt of northeast Hu⁃
nan. The different sizes of faults and faults strictly control the ore body shape and occurrence position of
each vein in the mining area.In the past，the research on the faults in the mining area was mostly concentrat⁃
ed on the NW-trending ore-bearing faults，while the research on the NE-trending F8 fault as the ore-con⁃
trolling structure in the mining area was insufficient.In order to further explore the influence of F8 fault on
the metallogenic structure of the mining area，starting from the unknown fault in the underground -380 m
middle section project，the geometric model and data comparison method are used to verify that the fault is
the extension of the surface F8 fault in the underground part.The study shows that the F8 fault may be a
right-lateral reverse fault，and it is formed in the same period as the northeast-trending fault around it，
which together acts as the ore-controlling structure formed by the ore veins in the mining area.The hanging
wall traction fold is affected by the fault structure and can often form joint veins.The research is of great help
to improve the resource reserves of the mining area and improve the prospecting efficiency.
