Abstract

Hot and humid mine atmosphere can produce a strain on the human body. The study of water vapor in air is known as psychrometry and psychrometric properties of mine air allows to calculate the heat and moisture content. The psychrometric conditions of mine air have a great effect on the health, safety and productivity of employees. When considering the climatic conditions of a mine, the high temperature and humidity problem must be considered. Thus, it is possible to find out the heat and moisture content of air by making psychrometric calculations. In this study, measurement studies have been carried out to determine the increase of heat and humidity in a coal mine using mechanized production method in Turkey and then, heat and moisture exchanges in mine air were calculated. At the end of the study, according to EN ISO 7243: 2017, the amount of required air flow to provide the acceptable climatic conditions was calculated.
