摘要：

The law for permeability of coal body containing methane considering coupling effect of heat and stress has been experimentally researched in this article. Permeability measurement experiment has been done under different axial compression, confining pressure, pore pressure, and temperature by using the Triaxial Permeameter. Through analysis of the experimental results, the permeability of coal presents an increasing trend with the increase of pore pressure, and the increasing trend is more significant with the increase of temperature; the permeability of coal presents a decreasing tendency with the increase of effective stress, and the decreasing tendency is more significant with the increase of the temperature.
