Variation Law of Infrared Radiation Temperature of Unloading Fracture of Composite Coal-Rock

Figure 2

Cloud map of temperature distribution of composite coal-rock. When the simulation time is 25 s, 60 s, 90 s, 130 s, 146 s and 175 s, cloud maps of temperature distribution of composite coal-rock at different times correspond to different stress stages in Figure 1, in which 146 s is the time point after unloading confining pressure.
