Abstract： To study the influence of airflow temperature by surrounding rock, this paper discussed the periods of heat regulating ring formation and the factors influencing the heat regulating ring. The airflow in dry roadway affected by surrounding rock is simulated by FLUENT. The study finds that the temperature of airflow under the influence of surrounding rock is obvious with the slow airflow. With the increasing distance of the airflow the changing temperature of airflow is related to the radius of heat regulating ring. The process of the airflow temperature changing can be divided into three stages: preliminary stage, stroll stage and the stabilization stage. The ratio of each stage in roadway based on length shows that preliminary stage 77.2%, stroll stage 11.55% and the stabilization stage 11.25%.
