    • Abstract
  • Based on raw coal specimens of No.9 seam of Linhua Coal Mine in Guizhou Mining Area as study objects, it carries out triaxial seepage tests under different pore pressure and temperature with independent triaxial seepage device that the outlet pressure could be adjustable. It shows that when the inlet gas pressure is constant and the pore pressure changes between 1.8 and 2.4 MPa, the permeability of raw coal containing gas changing with pore pressure is the exponential function relationship; when the pore pressure is constant, the permeability of raw coal containing gas decreases with the increase of temperature. But the degressive extent varies according to the increase of temperature. The two obey the power function distribution; if the pressure difference is constant, the permeability of raw coal containing gas decreases with the increase of temperature. When the temperature is constant, the permeability of raw coal containing gas decreases with the increase of pressure difference; by means of the above experimental results, the functional relation between the permeability of raw coal containing gas and the coupling effect of pore pressure and temperature is derived.
