摘要
结合目前的采煤实践,设想了突水系数公式的发展趋势。通过磁西一号井田实例,证实了突水系数法在预测开采深部煤层突水危险性评价中的局限性。表明在深部煤层突水危险性评价应用时,其它方法作为突水系数法的补充,可为含水层富水性较弱而突水系数较大的深部开采底板突水安全评价提供参考依据。
The development tendency of formula of the method of water inrush coefficients was pointed out by combining with the current practice of mining.Taking well field of CIXI for example,the limitation of water inrush coefficients for evaluating risk of floor water inrush in deep mining was proved.Other methods can be a supplement for evaluating water inrush coefficients for evaluating risk of floor water inrush in deep mining.The achieved results can be provided for evaluating water inrush risk of floor in deep mining of some mining areas,in which the water-enriched properties of aquifer are not obvious but water inrush coefficient is larger.
