The present paper deals with a new nodal-point method for the analysis of a mine ventilation network. The new method adapts a new approximation procedure of static pressure at each nodal point which is obtained by minimizing the total energy loss of flows around the nodal-point. The present method was successfully applied to a simple model of a ventilation network. The results of calculation were compared with already-reported methods by Inoue and Uchino and D. Scott and F.B. Hinsley. It has been found to possess simplicity of procedure and rapid convergence with high accuracy for the answer to any initial values of nodal-point pressures.
