摘要
基于Knudsen方程,以瓦斯气体的平均分子自由程和煤体裂隙的平均孔径为突破点,根据二者在诸因素影响下的相对关系,重点分析了煤体含水率、界面张力、孔隙压力以及有效应力对瓦斯滑脱行为的影响。
Based on the Knudsen equation, the mean free path of the gas molecules and the average pore size of fractures in coal fissures are the breakthrough points. Based on the relative relationship between the two factors under many influencing factors, analyzed the effect of coal moisture content, surface tension, oore pressure and effective stress on aas sliDDaze behavior especially.
