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