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,至今对它的研究仍处于近似计算的水平。"大井法"预测矿井涌水量由于简单方便,经常被大家所使用。但是通过对该方法的理论及实践分析认为,它并不适用于大降深、不规则矿井的涌水量计算预测,并以锡林格勒盟××煤矿和山西省××煤矿为例进行了论证。最后,建议矿坑涌水量计算时,尽量采用数值模拟方法,并辅以其它类比外推方法等。
The calculation of mine water inflow is not only an important and complicated work in mine hydrogeological exploration, but also one of the fundamental missions in mine hydrogeological exploration. Because of the complexity of mine hydrogeological exploration conditions ,we can only study it in a proximate calculation way. Because of its simplicity, the＂ Open well method＂ predict of mine water inflow often appear in some exploration reports. However, after making an analysis on the theory and practice of this method, we find that this method is not appliable to the calculation predict of water inflow in irregular mine,and take two example to explain it. We advise that numerical simulation method and other analogy and extrapolation method etc ,be applied when making a calculation of mine water inflow.
