| 摘 要： | 在经典瓦斯流动理论基础上，将瓦斯在采动工作面前方煤层中的流动视为流动边界不断变化的一维流动问题，利用动坐标变换，求出在这种情况下瓦斯压力分布的解析解，比较了不同的工作面推进速度对瓦斯压力分布及瓦斯涌出量的影响。

| Abstract: | In this paper,the gas flow in the coal seams which are in front of advancing coal face is considered as the one--dimension flow problem in Which the flow boundary is constantly changing.Take advantage of the transformation of moving coordinate, the analytical solution for the distribution of gas pressure in the above case is sought. Furthermore,the influnces on the distributionof gas and gas discharge by various speeds of face are compared. |
