dc.description.abstractThe control of thermal environment in underground structures has always been a subject of great concern. In this paper, the influence of initial surrounding rock temperature (ISRT), ventilation temperature (VT) and ventilation volume (VV), as well as internal heat source intensity (HSI) on the temperature control of ventilation risk in underground closed space is explored by building a 50-person Mine refuge chamber (MRC) model with internal heat source. The model is verified according to the experimental data, and the relative deviation is less than 4.3%. The simulation results show that the indoor temperature (IT) is proportional to the ISRT, HSI and VT, but inversely proportional to the VV. When there are 30 people in the MRC, the ISRT and the initial IT are 32°C, the VT is 20°C, and the VV should exceed 450 m3/h to meet the temperature control requirements of 96h. Taking into account the comfort of personnel, it is recommended that the air volume of 900 m3/h is more appropriate for 30 people.en
