摘要
根据某矿2315工作面实际情况构建了Fluent数值模型,对该工作面沿走向和倾向的瓦斯浓度分布进行了数值模拟分析,得出了采动裂隙"O"形圈内瓦斯运移规律。根据瓦斯浓度分布规律对工作面瓦斯抽放钻孔参数(钻场有效高度、钻孔有效长度以及钻孔与回风巷的水平距离)进行了设计,取得了理想的瓦斯抽放效果,对于类似矿山瓦斯灾害治理有一定的参考价值。
According to the actual situation of 2315 working face of a mine,the Fluent numerical model is established, so as to conduct simulation analysis of the gas concentration distribution of the strik- ing and tendency of the working face,the gas migration regularities of ＂ O＂ ring in mining fissme is dis- cussed. Based on the gas concentration regularity, the borehole parameters （drilling effective height, drill- ing effective length and the horizontal distance of drilling and air retum roadway） of gas drainage of the working face are designed, the ideal gas drainage effects is obtianed ,which can provide reliable reference for the gas drainage of similar mines.
