| Abstract: | The complex state of gas flow in goaf was simplified. The nonlinear seepage equation of mixed gases in a three-dimensional goaf was established and three different boundary conditions were given. In the light of the velocity field acquired, a mathematical model of the temperature field in the goaf was established, which provided theoretic bases for realization of a three-dimensional steady flow field and computer simulation of the temperature field in the goaf. |
