摘　　要：结合五阳煤矿7605高瓦斯综放面地质生产条件,通过建立三维CFD模型对全岩瓦斯尾巷瓦斯抽排效果进行了对比分析。数值模拟对比分析与现场实测结果表明:全岩瓦斯尾巷能有效将上隅角及回风巷瓦斯浓度降低到0.8%以内,减少了断电次数,为工作面稳定生产提供了保障。Gas concentration has important influences on mine production. According to the geological conditions of 7605 high gas fully mechanized caving face in Wuyang Coal Mine, this study constructed three dimensional Computational Fluid Dynamics （CFD） models for analyzed whole rock gas tail roadway drainage effect. The results of numerical simulation and site measurement show that the rock tail roadway can effectively lower the gas concentration to less than 0.8% at the upper corner and ventilation roadway, which reduces the number of power off and enables stable coal production.
