| 摘 要： | 利用NetpathXL 2．14对皖北矿区典型煤矿（朔里矿、张庄矿、杨庄矿和刘二矿）太灰水的地球化学特征进行了模拟。并结合与区域构造有关的地貌特征和水文地质条件对该区深层地下水径流规律、控制因素、地下水子系统划分及煤矿开采过程对深层地下水的影响进行了讨论。模拟结果表明：皖北矿区太灰水径流受不同的地下水子系统控制．其中朔里矿-张庄矿-杨庄矿与刘二矿处于不同的水文地质单元．朔里矿-张庄矿-杨庄矿太灰水径流主要与区内北高南低的地形有关自北东向南西流动的；朔里矿-张庄矿段太灰水的补给和排泄可能受到了矿井人工排泄的影响，但太灰水主体径流方向并未明显改变；对张庄矿-杨庄矿段而言，需要着重考虑区内太灰水的补给和排泄情况。以防止相关突水事故的发生。

| Abstract: | The Taiyuan Formation limestone aquifer groundwater characteristics have been simulated for typical coalmines （Shuoli, Zhangzhuang, Yangzhuang and Liuer mines） in the northern Anhui mining area, through the use of the Netpath XL 2.14, combined with landform features and hydrogeological conditions of the area, discussed groundwater runoff pattern, controlling factors, subsystem division and deep groundwater impact to coal mining. The simulated resuhs have demonstrated that the Taiyuan Formation limestone groundwater runoff is controlled by different groundwater subsystems, in which, Shuoli, Zhangzhuang and Yangzhuang coalmines situated in a hydrogeological unit different from the unit Liuer coalmine situated, runoff of the former is flow from northeast to southwest, in accordance with the high north and low south relief; in Shuoli-Zhangzhuang sector, the recharging and discharging of the limestone water may be influenced by coalmine artificial drainage, but the principle direction of runoff has not been changed obviously; as for Zhangzhuang-Yangzhuang sector, the recharging and discharging of limestone water need to be considered emphatically, in order to prevent related water burst hazard. |
