Based on the mathematical model for rock temperature distribution in a geothermal field
the properties of rock temperature distribution in geothermal field for four kinds of surrounding rock cross-sections of deep mine tunnels
has been simulated by using finite element method. It is shown that the relationship for rock temperature distribution varied with the geothermal parameters
time and space. Namely
2-dimensional time-dependent isograms clearly showed the process for rock temperature variation and distribution in a geothermal field which has been redisplayed with visualization numerical simulation.
