突水系数理论在淮南矿区的应用

通过对华北矿区水害特点的分析，说明了突水系数理论应用的重要性；根据多年来我国煤矿区突水发生的特点，对突水系数应用的理论性进行了推导，并对华北煤田临界突水系数进行了统计分析，着重总结了淮南矿区突水系数理论的实际应用。结果表明：由于工程地质及水文地质条件的不同，华北煤田不同矿区的临界突水系数是不同的，矿区安全水头的确定要充分考虑矿区的岩性、地层组合特征、地下水赋存条件及岩溶程度等多种因素。

The Application Theory of Coefficient of Water Inrush and The Practice Foundation Applied in Huainan Coal Area

By brief analysis of water harm characteristics of northern china coalfield, the significance of the theories of Coefficient of water inrush is illuminated. According to the characteristics of many years of water inrush occurred in our country coalmine area, coefficient of water inrush is deduced. Statistic analyzed the critical coefficient of water inrush of northern china, the practical application of the theories of coefficient applied in Huainan coal area is emphasized conclude. The result express ： due to the different of engineering geology and hydrologic geology condition, the critical coefficient of water inrush applied in different coal area of northern china is different too. The determination of coalfields safety water head must sufficiently considered multifactor, such as lithology, assembled character of stratum, occurrence condition of groundwater and karst degree and so on.
