三轴应力对煤层渗透性的影响

Influence of Triaxial Stresses to Permeability of Coal Seams

摘要:

在试验的基础上，结合岩石力学知识，探讨了渗透压、围压和轴压对煤层渗透性的影响规律，并对此进行了理论分析。论证了模拟试验对评价煤层渗透性的意义。

Abstract:

on the base of tests ,the influence of osmotic pressure,confined pressure and axle pressure to permeability of coal seams are discussed combining with rock mechanics,and theortical aralyses are conducted onthem,and the meaming of evaluating permeability of coal seams by using simulated test is demonstrated.
