摘　　要：在地质与水文地质资料系统分析的基础上,以构造动力演化为主线,深入探讨了陕渑煤田构造发育、组合、性质及其分布规律,阐述了地质构造对地下水的控制机理。结果表明:印支期和燕山期构造运动奠定了陕渑煤田主体构造格局,构造运动不仅控制了含水系统的结构形态,而且直接影响到地下水动力条件,尤其燕山期形成的NNE向构造对含水层改造最为明显;地质构造越复杂,岩层富水性就越强,且富水区多位于断层端部或其两侧影响带范围内;矿井突水点在构造复杂区域分布显著增多,大部分的突水点位于小断层附近,褶皱轴部及转折部位也是突水的高发区域。On the basis of analyzing geological and hydrogeolgical data systematically,with structural evolution as the major line,this paper deeply discussed the regularities of development,composition,properties and distribution of structures,expounded tectonic controlling mechanism on groundwater.The result shows that tectonic movements not only controlled the structure of the aquifer system,but also directly affected the groundwater dynamic conditions,especially the NE-trending structure formed in Yanshan epoch transformated aquifers obviously;The more complex the geological structure is,the stronger the water abundance of rock became;The number of water inrush points in the complex structure region increased significantly,most of them were located near small faults,fold axis or turning position are also high incidence area of water inrush.
