The design of auxiliary ventilation system (AVS) and optimal equpment selection can be a problem, especially in case of very long drivages and high rock temperature.Algorithms for calculation of AVS parameters are basically developed by use of essential relationship from fluid mechanics. In a leaky duct, in addition to the variation of pressure, the flow rae varies along the duct and calculations are not straightforward. In the paper some of most successful models have been generalized and algorithms for calculations presented.Two basic models of leaking ducts are discussed:1st model for a duct with leakage through the flange joints: 2nd model for a duct with an equivalent longitudinal aperture.The presented analytical system has been successfully applied to developing a computer program, named DAVentS.A sample problems are used to illustrate the efficiency and accuracy of DAVentS software in solving most common problems in the process of designing AVS and especially in the process of equipment selection.
