Abstract: Using self-developed temperature-pressure (T-P) coupling gas migration experiment system, we carry out uniaxial compression experiment for coal samples from Sichuan Furong Baijiao Coal Mine under different engineering temperature (20 ℃, 25 ℃,30 ℃, 35 ℃ and 40 ℃) to study the influence laws of temperature on the physical and mechanical properties of deep coal rock. The results show that the uniaxial compressive strength and elastic modulus decreases with the increase of temperature; the higher the temperature, the greater the falling gradient of mechanical parameters. According to the variation trend of gas escape amount in constant temperature stage under different temperature, we think that the desorption migration of adsorption gas has very important role to affect the coal rock mechanics properties.
