摘　　要：基于矿井物探、钻探等勘查资料,结合区域地质背景,系统分析了矿井的构造特征,在此基础上,总结了矿井的控煤构造样式。研究表明:矿井主体构造为以阜凤逆冲断层为主推覆面的后展式逆冲推覆构造,构造线方向为近东西向;逆冲推覆构造具备完整的上覆外来系统、主推覆面和下伏原地系统。控煤构造样式包含单斜断块型、堑垒构造、逆冲褶皱型、挤压断块构造等,其中以单斜断块型和堑垒构造为主。Based on coalmine geophysical prospecting, drilling etc. exploration data, combined with regional geological setting, systematically analyzed mine structural features, and then summarized coal-controlling structural pattern. The study has shown that the main structure of the mine is a backward propagated thrusting nappe structure taking the Fufeng thrust as the main nappe surface, lineament is near EW. The thrusting nappe has an intact overlying allochthonous system, main nappe surface and underlying autochthonous system. Coal-controlling structural patterns have monocline fault block, graben-horst, thrusting fold and compressive fault block types, and mainly the former two.
