摘　　要：基于高河能源E1316工作面地质条件,利用Gambit软件建立综放面采空区的数值计算模型,用FLUENT数值模拟软件对高河能源Y+L型通风瓦斯流场特征及其分布规律进行了模拟分析。研究表明,工作面瓦斯含量主要集中在靠近回风顺槽一侧,且随联络巷间距的增加而下降,综合确定了合理的联络巷间距为30 m,为工作面巷道的布置与优化提供了科学依据。Based on the geological conditions of E1316 working face in Gaohe Energy,Gambit numerical calculation model for the goaf in the face is established.The characteristics and distribution law of the gas flow in the field of Y plus L shaped ventilation system are analyzed with FLUENT numerical simulation software.The research shows that the gas content of the working face is mainly concentrated on the return air side,and the gas content decreases with the increase of the distance between the crosscuts,and a reasonable distance between the crosscuts is determined to be 30 m,which provides scientific basis for the layout and optimization of the working face roadway.
