摘　　要：矿井涌水量计算是矿床水文地质勘查中一项重要而复杂的工作,也是矿床水文地质勘查中的根本任务之一。由于矿床水文地质条件的复杂性,至今对它的研究仍处于近似计算的水平。"大井法"在预测矿井涌水量方面具有简单方便的特点,故一些勘查报告中经常用采用该方法。但是,通过理论分析及实践,认为该方法并不适用于大降深、不规则矿井的涌水量计算预测,建议矿坑涌水量计算时,尽量采用数值模拟,辅以其他类比外推方法。The esti marion of mine water inflow is not only an important and complicated work, but also one of the fundamental missions in mine hydrogeological exploration. Because of the complexity of mine hydrogeological conditions, we can only study it in approximate computation way. Because of its simplicity, the ＂virtual large diameter well＂ method to predict mine water inflow is often appearing in some exploration reports. However, after making an analysis from theory and practices of the method, we have found that the method is not applicable to estimate water inflow of large drawdown and irregular shaped mines, and take two examples to explain. We advised that to use numerical simulation method when possible and supplemented by other analogy and extrapolation methods.
