摘　　要：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.
