近年来地方小井关闭数量迅速增加。闭坑之后小井本身形成大量的积水区，且积水空间分布、积水量和水压等情况不清楚。这些情况诱发了对邻近大型生产矿井水文地质条件的巨大变化，威胁了其安全生产。该类问题已成为我国很多矿区下一步面临的重特大水害事故的危险源。本次主要结合一些矿区实例对上述问题进行了深入分析，得出地下水系统演化规律，并给出了水文地质变化特征，如区域地下水水位抬升、地下水径流方式的改变等。

In recent years,the number of the local small closed-down coal mines increases rapidly.There is a lot of groundwater in the small mines after their closure,and the spatial distri-bution of water,water volume,water pressure and other conditions are not clear.These have in-duced the great changes of hydrologic geology of adj acent state-owned coal mines and threatened their production security.This kind of problem has become the risk sources of major water disas-ters in Chinese coal mines in the future.Combining with many mining areas as instances,the pa-per makes a deep analysis,and gets the evolution law of the groundwater system,and gives the changing characteristics of the hydrologic geology,for example,regional groundwater level rising and groundwater runoff way changing,and so on.
