Evaluation Method Applying to Miner Thermal Comfort

By establishing the mathematical model of body thermal equilibrium,the paper analyzed the relevant factors which affect miner thermal comfort.It is thought that the skin average temperature is determinant to control the heat exchange between body and environment.Taking three representative miners in Dongtan coal mine working face for example,the PMV and PPD values are calculated when the miners are in different positions.Miner thermal comfort is evaluated by the corresponding thermal sensation.
