摘要
本文以山西省汾西矿区崔家沟井田断层构造的展布规律、断层面构造岩特征及断层滑动擦痕为依据，分析断层发育的力学机制及成生序次，应用赤平投影图解矿区两条主干断层，得出矿区三向主地应力轴方向的认识，提出一种在华北地区有代表性的煤矿区断层构造展布模式。这对断层的识别和预测具有指导意义。
A neo tectonic fault zone was discovered at Taihelingkou village of Daixian county,Shanxi province The main fault was developed between the bedrock and the Quaternary system,and the dip angle of fault plane shows a characteristic of the upper steep and the lower gentle On the downthrown side of the normal fault,there appears some reversely dragged anticline and normal fault.It indicates that the horizontal displacement and velocity of the fault may be greater than those of the vertical displacement.Therefore,it is a low angle normal fault possessing listric character and was formed in the course of rift extending
