根据阳泉煤层瓦斯流动符合达西定律的特点,建立了瓦斯流动方程。探讨了低透性煤层瓦斯抽放参数和抽放率的计算问题。煤层瓦斯含量由游离瓦斯量Γ_1,和吸附瓦斯量Γ_2两部分组成:(?)
According to the characteristics of gas flow in Yangquan Coal Mine meeting Darcy’s law, gas flow equations are established. This paper discussed the calculation of gas drainage parameters and drainage rate of low permeability coal seam. The gas content in the coal seam is composed of the amount of free gas Γ_1 and the amount of adsorbed gas Γ_2: (?)
