工作区处于近东西向短轴向斜东部扬起端, 位于区域上两个深断裂之间, 受此影响, 该向斜较为开阔、平缓。北西翼宽缓, 地层倾角一般2°～10°; 南东翼较北西翼陡, 倾角一般8°～20°; 为一不对称向斜。向斜核部位于工作区的南部, 出露地层白垩系下统清水河组地层, 两翼出露侏罗系下统三工河组、八道湾组地层上海竞博JBOapp苹果版下载公司。
The working area situates in eastern raising end along nearly east-to-west minor axis, between two deep fractures of the area, under this influence, the syncline is spacious and gradual. Northwest wing is spacious and gradual, dip angle is normally 2°～10°; the southeast wing is steeper than northwest wing, inclination angle is normally 8°～20°, is a asymmetry syncline. The syncline core situates in the south of the working area, exposed stratum cretaceous system lower series Qingheshui form stratum, two-wing exposed Jurassic System lower series Badaowan form and Sangonghe form.
因受卡拉麦里深断裂和阿克朔克南深断裂的影响, 普查区内大断层与其次级地表断层较为发育, 在区内北部, 大断层与其次级地表断层以北西～南东向为主, 断层面倾向北东, 倾角65°左右。断层多以压性为主, 其性质不明。南部大断层与其次级地表断层以南西西～北东东向为主, 断层面倾向南, 倾角60°--75°, 断层多以压性、压扭性为主, 其性质为逆断层。这些断层均在工作区边界的石炭系及其泥盆系地层中, 对区内含煤地层影响不大北京竞博JBOapp苹果版下载公司。
Subject to effect of Kalamaili deep-seated fault and Arkeshuokenan deep-seated fault, major fault and its secondary near-surface fault in the enumeration area are comparatively developed, in the north of the area, major fault and its secondary near-surface fault are mainly of northwest-southeast direction, fault inclines towards northeast by approximate angle 65°. Most faults are mainly of compression nature, its property is unclear. Southern major fault and its secondary near-surface fault are mainly of south-west-west to north-east-east direction, fault inclines to the south by approximate angle 60°--75°. Most faults are mainly of compression nature and compression/torsion nature, its property is reverse fault. These faults are in the carboniferous system and its devonian system stratum on the boundary of the working area, effect upon coal-bearing stratum is not large.
