Structural control mechanism on groundwater in Shanmian coalfield

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.
