摘要: 以王家岭煤矿12311工作面瓦斯抽采为工程背景,在分析高位钻孔抽采瓦斯理论的基础上,采用FLUENT软件对工作面采空区抽采瓦斯的分布运移规律进行了研究,并据此确定了最佳的瓦斯抽采钻孔布置方式。现场实际抽采试验验证了数值模拟分析结果的合理性,为相似工程条件下瓦斯抽采工作提供了依据。

Abstract: Taking the gas drainage of 12311 working face of Wangjialing Coal Mine as the engineering background,based on the analysis of the theory of gas drainage by high position borehole,the FLUENT software is used to study the gas distribution and migration in the goaf of working face.According to the simulation analysis results,the best gas drainage borehole arrangement method is determined.The rationality of the above simulation resutls is verified by the actual gas drainage results,which can provide realiable reference for the gas drainage under the similar engineering conditions of Wangjialing Coal Mine.
