Identification of heat sources with the thermodynamic approach in the underground mine

Underground mining ventilation system is one of the supporting activities in underground mining activities. In general, underground mines have air inlet (intake) and air out (exhaust) to meet a variety of comfort for the workers, especially thermal comfort. But along with the development and increase in underground mining production, the number of production accesses and the increasing length of tunnels and production equipment will certainly provide a change in ventilation conditions in the mine. Changes in ventilation conditions in the mine to heat which is usually often found in underground mines. Such conditions will certainly have an impact on the comfort, health and safety of workers to work. Analysis through a thermodynamic approach is one effort to identify the presence of heat sources in the mine easily. This effort is one way that can be done to overcome the problem of heat. So that it can easily determine the right way to heat control.
