摘要
通过对鄂尔多斯盆地西北部断裂特征的统计和分析,总结得出研究区由西至东断裂逐渐发育,断层走向由以东西向为主逐渐转变为以北北东向及近南北向为主,且断层性质由以正断层为主逐渐变为以逆断层为主的变化规律,并分析了其形成的内在因素;揭示了研究区从北到南断裂分布的分区特性;研究区内含煤岩系和煤层现今分布与构造形态之间的关系,结合实例详细分析了各类构造样式的控煤作用,为今后本区煤炭资源开采及构造活动研究提供借鉴意义。
On the statistics and analysis of fracture features in northwest Ordos basin, the fracture in research area gradually develops from west to east. The fault strike gradually changes from east-west dominated direction to north-northeast and trending near north-south dominated direction. The most faults also gradually transform from normal faults to thrust faults, which intrinsic factors are studied. The study discloses the partitioning features of north-south fault distribution and the relationship between the distribution and structural configuration of coal-bearing formation and coal seams. The coal control action of different structures were studied based on cases, which could be helpful for the future coal resources mining and tectonic activity study in the area.
