摘　　要：补给模数大井法通过调整引用影响半径计算值,看似解决了利用裘布依大井法公式计算矿坑涌水量常常偏大较多的问题,但问题的症结似乎不在于此,而是:裘布依公式明显不适用于矿坑排水水文地质条件,难以反映复杂的地下水动力场特征;大降深排水不仅改变了含水层水力性质,也不能保证有一定的渗出段厚度。利用能够反映地下水三维流特征的地下水动力学公式等方法来计算才是解决此类问题的合理途径。The calculated value of water yield of mine is normally larger than actual with traditional Dupuit large-well method. The problem can be solved with recharge modulus large-well method by adjusting the value of substitute influence radius. However, it is obviously not applicable for the complicated hydrogeological conditions with the Dupuit large-well method and it is difficult to reflect the complex hydrodynamics of groundwater; meanwhile,the deep drawdown changed the hydraulic properties of aquifer and there is no guarantee the certain thickness of exudate section. Therefore,it is advised to solve this problem with groundwater dynamic formula which is able to reflect the three-dimensional flow characteristics.
