The article considers questions of determination of basic features of ventilation system taking into account concrete aerodynamic properties of local ventilators. During task solution variants of use of polyvinyl chloride and rigid conduits were considered. The authenticity of the offered method is confirmed by numerical calculations. The practical value of the work consists in development of a universal ventilation system model for the dead-ended mine tunnel, allowing account taking of all of constituents of source of draught in different variants of ventilation.
