Development of Thermodynamic Based Network Analysis Program for Designing Underground Mine Ventilation Systems

The paper presents the development of a thermodynamic based network analysis model. It uses transient heat flow algorithm for computing the heat flow from strata and predicts the environmental condition in different branches of the network. Along with the environmental condition, the mass flow distribution in network is computed by using nodal pressure method based on linear theory approach. The algorithm has been coded using object oriented programming approach and it has been validated in actual field condition. The correlation is satisfactory.
