摘　　要：针对晋煤集团寺河矿二号井现采采空区瓦斯涌出量大且采用"并列双U"三进两回通风系统的特点,通过应用CFD模拟技术对采空区瓦斯分布进行了数值模拟,得出不同边界条件下采空区内高浓度瓦斯聚集区域和采空区瓦斯引排、抽采可行性研究结果,从而为该矿制定采空区瓦斯治理措施提供了科学依据。Aiming at the characteristics of large gas emission rate in mining gob and using ＂parallel two U-shape＂ ＂three-intake-two-return＂ ventilation system in No.2 well in Sihe Mine of Jincheng Anthracite Mining Group,the paper adopts the CFD simulation technology to conduct a numerical simulation on gas distribution in gob,and obtains the high-concentration gas accumulation regions under different boundary conditions and the feasible research results of gas draining and extracting in the gob,which provide scientific basis for the mine to make the gob gas control measures.

关 键 词：瓦斯运移 数值模拟 引排 抽采
