Research on Ambient Temperature Change Law in Mine Refuge Chamber during Temperature Rise
ZHOU Fangnian
Abstract：To counter to the influence of thermal environment caused by the heat produced by human bodies and equipment on the persons in the mine refuge chamber, study was made on the dynamic coupled heat transfer regularity of air and surrounding rock wall in a sealed refuge chamber without any cooling measures. By using the theoretical analysis and tests, the calculation method for heat produced by human bodies and equipment and the temperature rise regularity in the refuge chamber in the escape period were obtained. This research result has a certain theoretical guiding significance for the control of the hot-moist environment in the mine refuge chamber.
