Based on the equivalent continuous medium model and the multi-field coupling theory, the physical model of temperature field calculation of roadway surrounding rock under the action of fracture water, the seepage field and temperature field of the rock, and the coupling control equation are established. Through the parameter of boundary conditions, the numerical simulation is carried out with software FLUENT. The temperature distribution of roadway surrounding rock under the action of fracture water is revealed. The analysis shows that the migration of fracture water accompanies the heat exchange and the action of fracture water changes the temperature distribution form of roadway surrounding rock. The influence of seepage velocity of fracture water on the temperature distribution of both fracture water and roadway surrounding rock is analyzed quantificationally. In the flow direction of fracture water, the smaller the seepage velocity is, the greater the temperature rise of fracture water and surrounding rock are. When the flow velocity is greater than 2×10-8 m/s, the changes of seepage velocity have a significant impact on the temperature distribution of roadway surrounding rock. However, when the flow velocity is smaller than 2×10-8 m/s, the effect is slight.
