Effect of temperature and humidity on salt mine environment

The temperature and humidity of intake air changes the temperature and humidity of rock salt mine. The general trend of climate of Jhelum was analyzed to see the general characteristics of meteorological parameters of the region. Hot and humid summers, dry and mild winters, average annual precipitation above 900mm are associated with the climate of Jhelum. In Khewra Salt mines, the rock salt accepts the effects of parameters of influx air and shows the changes with sensitivity immediately. For this reason, the walls of salt mines are deteriorating. Resultantly, the changes in appearance, shape of salt walls, re-crystallization and generation of brine solution was observed in different proportions depending upon the distance from the entry of the mines. In an enclosed chamber of hygroscopic salt, as the temperature fluctuates absolute humidity fluctuates more than the relative humidity. The calamitous effect of changes in parameters of air on salt chambers and manifestation in different parts of salt mines should be limited. It is proposed that to protect the geological layers of the salt inside the salt mines where the destruction is high, ventilators should be erected and regulated in such a way that the levels of temperature and humidity might be maintained for frequent exchange of the parameters of air with the influx air.
