为掌握采空区覆岩导气裂隙带瓦斯渗流规律,采用理论分析与物理模拟的方法,对导气裂隙带进行了侧向区域划分,并对各分区瓦斯渗流特征进行了研究。结果表明:根据采动应力分布特征,采空区覆岩导气裂隙带在侧向上可分为压裂裂隙带、“O”形圈裂隙带、裂隙闭合带;在压裂裂隙带和裂隙闭合带瓦斯流态为达西渗流,在“O”形圈裂隙带瓦斯流态为紊流状态。 In order to understand the gas seepage law of gas permeable fracture zone in mined-out area, theoretical analysis and physical simulation methods were used to divide the gas-permeable fissure zone in lateral direction and to study the gas seepage characteristics in each area. The results show that according to the characteristics of mining stress distribution, the gas-bearing fractured rock strata in the goaf can be divided into fracturing fractured zone, “O” shaped fractured zone and fractured closed zone laterally. In the fracturing zone and The fractured closure zone gas flow regime is Darcy seepage, and the gas flow regime in the “O” ring fracture zone is turbulent.
