主　　题：high-temperature environment heading face dehumidification thermal comfort WBGT 

摘      要：In order to improve the thermal environment of high-temperature heading face,moisture content of supply air is reduced by dehumidification, and the relative humidity ofenvironment air of the heading face is also ***, according to the coefficient ofperformance of dehumidifier, the capacity of dehumidification was ***, inthe engineering example of the heading face, quantitative changes of WBGT (Wet BulbGlobe Temperature) were compared between with dehumidification and without *** on WBGT standards, the thermal comfort of high-temperature environmentof heading face was evaluated between with dehumidification and without *** relative humidity of airflow through dehumidification, the thermal comfort of ahigh-temperature environment of heading face can improve *** if dry bulb temperatureof airflow is not decreased, the thermal comfort of heading face environment isalso improved to some extent.
