Measurement and Analysis of Thermal Insulation and Evaporative Resistance of Coal Mine Ensemble by Thermal Manikin

In this paper, the thermal insulation and evaporative resistance of five ensembles from Huainan Dingji Coal Mine, Jining Anju Coal Mine, Lu'an Wuyang Coal Mine and Shendong Jinjie Coal Mine were measured by thermal sweating manikin in a climatic chamber. It is found that the thermal insulation and evaporative resistance of the ensembles for Dingji and Anju hot mines are larger than the ensembles for Wuyang and Jinjie Coal Mines; the thermal insulation of the ensemble worn for one year changes slightly from the new one, but the evaporative resistance decreases about 13%; the local thermal insulation and local evaporative resistance of these five mining ensembles vary significantly.
