Experimental study of phase change material's application in refuge chamber of coal mine

We identified the main heat source of the refuge chamber was hedge staff by analyzing the heat source of the refuge chamber. We identified the calculation method of the heat released by the hedge staff and calcium hydroxide when absorbed CO2. We designed the experimental program of temperature control of phase change material according to the estimate of heat dissipating capacity in 96 hours. Ultimately, we conducted simulation experiments and verified the effect of temperature control of the phase change material. (C) 2012 The Authors. Published by Elsevier Ltd.
