The three-dimensional temperature field of the coal-bed methane with heat injection was numerically calculated by ANSYS. The calculated results revealed that the temperature, the thermal gradients and the thermal flux vector sum of the coal-bed near the injection well was higher, while was smaller at the other area of Coal-bed Methane (CBM), which indicated that the coal-rock was not affected by heat but maintaining the initial temperature in a more distant, In addition, as time increased, the radius of heat injection for CBM also increased, so the produce of coal-bed gas would increase and the desorption was easier in the range of heat diffusion after heat injection.
