. As shown in Figure 5, the test block of CTB (38 cm×12 cm×50 cm) used in the experiment has embedded copper tubes and thermocouples. Tailings and cement were used as aggregate to prepare filling slurry...-temperature water in water tank into embedded copper pipes. Taking the central point of CTB as the research object, the temperature value of experimental test is compared with the simulation result. Figure......
