| 摘 要： | 本文研究了钻孔周围的扰动应力对瓦斯渗透性的影响.还研究了瓦斯的实际状态方程,并通过对这些复杂关系的线性简化,首次提出了考虑岩压作用和瓦斯实际状态的抽放瓦斯渗透方程。计算结果表明:(1)对于低透气性煤层,本文模型较旧模型更能反映实际.(2)理想气态方程因会带来较大误差而不宜采用。

| Abstract: | In the paper,the influences of the disturbing stresses around a borehole on the permeability of the gas in coal seams and the real gas state are studied. Based on linearizing the complicated relationships,the pumped gas permeation equation containing rock pressure and real gas state is first presented.The results of computation indicate: (1)the new model for the hypotonic coal seams mirrors the reality more than the old one. (2)the equation of the ideal gas state would not be used because of its greater errors. |
