摘　　要：针对工作面上覆巨厚关键层的开采条件,采用相似材料模拟实验方法,研究了巨厚关键层影响下采动裂隙的分布特征,并以此为根据提出了瓦斯运移富集特征。研究结果可为巨厚岩层下工作面开采瓦斯突出的预测与防治工作提供一定的理论基础。According to the working face and thick overlying key strata mining conditions, using the method of similar material simulation, the distribution characteristics of fissure effect of thick key strata under mining, and then puts forward the characteristics of gas migration and enrichment. The results of this study can provide a theoretical basis for the prediction and prevention of gas outburst in the face of mining under thick strata.
