摘要
In order to study the temperature distribution of deep field,mathematical mod- els of temperature field in field and surrounding rock were built based on heat transfer and seepage theory.Combined test data with mathematical model,the temperature distribution under heat-transfer and underground-water coupling was studied by using Golden Soft- ware Surfer and Matlab.The results show that distribution law of most isothermal lines is very similar in deep field,and temperature gradient is equal in general.At the same time, temperature distribution is influenced by underground-water and fault.In surrounding rock, seepage changes symmetrical distribution of temperature field and vector,and the tem- perature field may divide into inward-diffusion area and outward-diffusion area.Peripheral temperature of working will approach to the temperature of airflow.In inward diffusion area the distribution of temperature and temperature vector is symmetric,and the direction of temperature vector point to the center of working.The action of airflow is stronger than seepage in inward diffusion area,however,the case opposite is true in outward diffusion area.
