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。
Aiming at the mining conditions of overlying thick and thick key bed, the similar material simulation experiment method was used to study the distribution characteristics of the mining fractures under the influence of thick and thick key layers. Based on this, the gas migration enrichment characteristics were proposed. The results can provide a theoretical basis for the prediction and prevention and cure of gas outburst in the working face under thick thick rock.
