| 摘 要： | 在考虑煤骨架吸附变形特性的情况下,得出了孔隙率、渗透率和膨胀变形之间的关系式。分析可知,煤层中瓦斯压力越大,产生的膨胀变形越大,孔隙度越小,煤层的渗透性越差,瓦斯流动越困难。 |
| 关 键 词： | 孔隙率 渗透率 膨胀变形 |

| Abstract: | This paper founds the relation of porosity, permeability and swelling deformation under considering swelling deformation made by coal adsorption gas, and by analysis it can be concluded that as gas stress in the coal bed increases, the swelling deformation becomes bigger, the porosity being much smaller, so as to weaken the permeability of the coal bed and make it difficult for gas flow. |
| Keywords: | porosity permeability swelling deformation |
