摘　　要：会泽铅锌矿床是我国著名的超大型特富铅锌矿床之一,断裂构造控矿明显。对麒麟厂矿床深部(1 331~1 031) m中段范围内各坑道揭露的断裂、节理进行详细观测,并运用构造解析法、吴氏网投图法,确定了麒麟厂矿床深部多期次构造活动的变形特征及其主应力方向。研究结果显示麒麟厂矿床深部北东向断裂为成矿期构造,应力状态依次经历了张→压→扭的变化;北西向、近东西向断裂为成矿后构造。Huize lead-zinc deposit is the one of famous super large and extra-rich lead-zinc deposits in China,ore-controlling is obviously by fault structure.The detailed observations were carried out for breaks and joints revealed in tunnels in the range of(1331-1031)m of the middle part of the deposit deep section in Qilingchang,structural analysis,Wulff net map projection were adopted to confirm the deformation characteristics of multi-stages tectonic activity in the deep part of Qilingchang deposit and its principal stress orientation.Study results show that:the north-east fracture of the deep part of the Qilingchang deposit is the mineralization period structure,and the stress state sequentially underwent the following structural deformations:stress expansion→stress compression→stress twisting;north-west,near east-west fracture is the post-mineralization structure.
