将避难硐室内围岩结构与空气的耦合传热过程划分为升温期和恒温期两个阶段，结合半无限大物体传热理论推导出恒温阶段内围岩与空气的耦合传热计算公式。借助Fluent计算流体软件，模拟分析了避难硐室内围岩与空气传热规律及硐室内空气温度场的变化分布。%The coupling heat transfer process between air and surrounding rock in refuge chamber was divided into heating stage and constant temperature stage.The calculation formula of coupling heat transfer between air and surrounding rock in refuge chamber in the constant tem-perature stage was deduced in combination with the heat transfer theory of a half infinite obj ect. Fluent software was used to simulate the heat transfer law between air and surrounding rock in refuge chamber as well as the distribution of air temperature field in the refuge chamber.
