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.
