Structures in the Linhuan mining area, Huaibei coalfield are rather complicated. The Wugou coalmine is situated in the mid-dle sector, west limb of Tongting anticline, Linhuan mining area, within a mainly syncline compound folded structure combination, the counter S shaped syncline axis is cutting by faults. Based on systematic analysis of geological data concerning Wugou coalmine, com-bined with tectonic evolution, have discussed structural development features, evolution history and formation mechanism. Then summed up:①Wugou mine area can be divided into 3 structural zones:complicated faulted zone in the north, superimposed folded zone in the middle and structurally complicated zone in the south;faulted structure combination forms have λtype, Y type, graben-horst type and stepped type.②Mine area structural formation and evolution are obviously controlled by regional tectonics, the Indo-Chinese epoch NS tectonic compression caused the formation of near EW Wugou fault, then ended by the formation of Wugou synclino-rium;the Yanshanian epoch NW-SE intensive compression caused the formation of most distinctive NE faults and folds in the area;while the Himalayan epoch tectonic extension caused the formation of developed tensional structures, meanwhile transformed large and middle sized main controlling faults in the area into normal faults.%淮北煤田五沟煤矿位于童亭背斜西翼中段，为一向斜为主的复式褶皱构造组合，向斜的轴部呈反S形且被断层切割。在系统分析煤矿地质资料的基础上，结合区域构造演化，探讨了构造发育特征、构造演化历史及其形成机制。结果认为：①五沟矿区可以划分为北部断裂构造复杂区、中部褶皱叠加区和南部构造复杂区3个构造分区，断裂构造的组合形式主要有“入”字型、“Y”型、堑垒式及阶梯式。②矿区构造的形成及演化受区域构造控制明显，印支期NS向构造挤压作用形成了近EW向的五沟断层，末期形成五沟复向斜构造；燕山期NW-SE向强烈的挤压作用形成了区内最为显著的NE向断裂及褶皱构造；喜马拉雅期的构造伸展作用造成拉张性构造发育，同时也使区内大、中型主控断裂转变为正断层性质。
