By analyzing hydrogeological conditions of panxi coal, the coupling mathematical model of heat-transfer is developed in surrounding rock.Temperature field and seepage field distribution of fracture rock is described by using heat-transfer and seepage differential equations. Combined with boundary condition and parameters, the numerical solution is obtained by using numerical software. The results of numerical simulation show that the temperature of surrounding rock change under the influence of the seepage. Because of the temperature difference between the groundwater and the surrounding rock, heat axchange will occur on the coupling section. Eventually the temperature of water is similar to the surrounding rock and form the balance area of heat exchange. This indicated that heat transfer accompany the process of seeapge. At the same time, the balance area of heat exchange will move following leakage, and along with the seepage speed increasing, the balance area of the scope will enlarge. With the existence of the blance area, it becomes the watershed of the temperature vector change.
