摘要
Abstract
To study the temperature field of surrounding rock during its heat transfer process,25 sets of numeri-cal experiment models were established to simulate the heat transfer process of heat -adjusting layer.The origi-nal rock temperature,heat -adjusting radius and thermal conductivity was selected as influence factors,and the roadway wall temperature was considered as target factor.According to the orthogonal analysis,it is concluded that the effects on the wall temperature were ranked in the order of original rock temperature >thermal conduc-tivity >heat -adjusting layer radius.Based on the statistics analysis,the wall temperature thermodynamic cal-culation formula was fitted,and its correlation coefficient was 0.996.Finally,the ventilation time factor was broaden,then the relationship formula between heat -adjusting layer radius and ventilation time was fitted.The two calculation formulas can be used for evaluating roadway wall temperature.关键词
