| 摘 要： | 为了优化煤层钻孔瓦斯抽放参数,结合质量守恒定律和煤层瓦斯运移理论,以煤层抽放钻孔附近的瓦斯流场为研究对象,建立了瓦斯运移的数学模型。并以薛湖煤矿2307机巷掘进工作面为例,采用MATLAB对煤层钻孔瓦斯流场进行了数值模拟,并与矿井的实际瓦斯抽放情况作了对比分析,得出了适应该矿区煤层的瓦斯抽放参数。

| Abstract: | In order to optimize the parameters of gas drainage,a mathematical model about gas migration law was established to study the gas flow field around boreholes,based on the law of mass conservation and the gas migration theory in coal seam.No.2307 working face of Xuehu Coal Mine taken as an example,MATLAB software was used to simulate the gas field around boreholes.The gas drainage parameters suitable for the coal mine were obtained by comparison with simulated results and those from the practical gas drainage. |
