Abstract: By using self-developed triaxial servo-controlled seepage equipment for thermo-fluid-solid coupling of coal containing methane, the permeability of moulded coal and raw coal under different effective stress are determined. Based on that, the effect of temperature on the two kinds of coal is discussed. For there are significant differences among the permeability of coal samples, temperature sensitivity coefficient is defined to eliminate individual differences, and temperature sensitivity coefficient can reflect the sensitivity of coal to temperature. Based on the definition, the sensitivity of the two kinds of coal to temperature is studied. The experimental results show that, if the effective stress is kept constant, the permeability of the two kinds of coal will decrease with the increase of temperature, and they approximately follow negative exponential function; the sensitivity of moulded coal and raw coal to temperature both decrease with the increase of temperature, and the sensitivity of raw coal to temperature is higher than that of moulded coal.
