摘　　要：以勘查资料为基础,结合已有研究成果,从鄂尔多斯盆地的构造演化、区域构造背景、构造特征进行分析,认为苏亥图地区发育7条北东向断层和3条近东西向断层,主断裂为北东向,断裂构造控制了煤系的展布,将煤系地层切割为北东走向的断块状。根据煤系与构造形态之间的关系,苏亥图地区构造控煤类型可划分为单斜断块型和逆冲褶皱型两种,其中以单斜断块型为主。Based on exploration data, combined with available research results analyzed structural features in the Suhat area from structural evolution and regional tectonic setting in the Ordos Basin. The study has considered that in the area have developed 7 NE faults and 3 near EW faults. The main faults are NE stricken and controlled coal measures strata extending and cut them into NE strike fault blocks. The coal controlling structures can be partitioned into monoclinal blocks and thrusting folds two types and mainly the former type.
