在矿山开采过程中会存在矿坑涌水，为了使矿坑涌水得到合理的利用与疏排以及防止突水事件发生，需要对矿坑涌水量进行预测。以安徽省涡北煤矿为例，使用数值法与解析法分别预测其开采中产生的涌水量，并对两种方法预测结果进行分析比较。对数值法的应用是根据矿区水文地质条件，利用Modflow软件对矿区地下水进行模拟计算；解析法则主要依据地下水动力学的研究，使用解析公式计算矿坑涌水量。结果表明，两种方法都是合理的，这两种方法的结合增加了矿坑涌水量预测的可靠程度，可相互佐证。

In order to make reasonable use of pit mine water which occurs with the mining process , and prevent the occurrence of water inrush , pit mine water needs to be predicted.Take Guobei coal mine in Anhui Province as an example , numerical method and analytical method are used to forecast mine pit water and analyze two kinds of result.Application of numerical method based on hydrogeo-logical conditions in mining areas is using the software named modflow to carry out simulated calcula-tion.While analytical method based primarily on studies of groundwater dynamics is using analytical formulas to calculate mine pit water.Results indicate that both methods are reasonable , the combina-tion of these two methods increasing the reliability of the forecast , they can support each other.
