| Summary: | Underground ventilation system, hold important roles as quantity, quality and temperature-humidity controls to create and maintain a proper working condition, based on regulation employed. As mining processes are continuous and dynamic, it is necessary to maintain continuously and dynamically planned ventilation system as well as its processes. Before the ventilation system was developed, assessment of current ventilation system should have been conducted previously as guidance. <br />

As the complexities and many of parameters that have to be taken into consideration, the use of microprocessor was necessary in order to provide more rapid and accurate calculation. A computer software, Mivena (Mine Ventilation Analysis) has been developed since 1986 at Akita University, Japan, applied Nodal Flow Potential approach instead of Hardy Cross Method that have been widely used recently. Mivena was also designed to be able to predict influence of heat transfer and/or evaporation to psychrometric condition of Underground environment such as Natural Ventilation Pressure, change of specific volume, etc. <br />
