Rock and Soil Mechanics
In order to investigate the influence of temperature in deep coal mining area on coal seepage and pore fracture structure deformation, 3D CT reconstruction technology and ANSYS were used to simulate the process of conjugate heat transfer and thermal deformation of coal microstructure respectively. The conjugate heat transfer simulation results show that water was initially injected into the 80℃ coal wall at 20℃ was heated to 37.13℃ when it flows out. The temperature of the coal gradually decreases along the wall facing the fluid center. Pore fracture structure has an important influence on the velocity and the temperature of the …
