This paper deals with application of the Sequential Unconstrained Minimization Technique (SUMT) for solution of the problems of partially controlled air distribution in mine ventilation networks. All papers in this area in Yugoslav mining literature [8], [14], [13] , and practice were based, particularly when use of contemporary computers are in question, on the well known Hardy Cross Iterative Method. Having in mind that the problems is related to nonlinear programming, the SUMT method can be used to find optimal solution.
