摘要
通过对实际资料分析，研究了影响煤层底板突水的主要因素。依据试验获得的参数，建立了华北地区带（水）压开采评价准则及预测模式；并举例说明了应用方法。最后对华北典型大水矿区进行了总体分区。
Through the analysis of practical data,the main factors influenced on the water gushing of seam floor are studied.Based on the parameters obtained from the tests,the evaluation criteria and prediction model of mining under water pressure in North China are established,and the application method is illustrated with examples.Finally,the overall division of typical mining district with large water yield in North China is given ,and the corresponding control measures are presented.
