In order to research thermal conductivity of fracture rock, fluid-heat coupling test and simulation are studied. Empirical equation of thermal conductivity is obtained and conductivity factor is ensured by test data. Based on the fluid-heat coupling model of heat-transfer, temperature field distribution of fracture rock is described. At the same time, the heat-transfer equation is discretized by using weighted residual Galerkin finite element. Combined with boundary condition and parameters, the temperature field in fractured rock mass is simulated by finite element method. The temperature of fractured rock mass under the action of the seepage is combined with the initial rock temperature, fluid temperature and the rate of the flow. Thermo-isoline is discontiguous at boundary of fracture, which shows that the seepage affects the distribution of temperature field. The change rate of temperture isoline is gradually reduced along the single fissure flow, therefore the rate of heat-transfer is decreased. The influence of fluid temperature to temperature distribution is small, but different fluid temperature obviously affects thermo-isoline.
