Annotation:

The questions of determination of basic features of the ventilation system in dead-ended mine workings are examined taking into account concrete aerodynamic descriptions of ventilators of local ventilation. Variants using flexible conduit for solving the problem are considered. Authenticity of the offered method is confirmed by numerical calculations. The practical value of work consists in development of universal model of the ventilation system of the dead-ended mine working, allowing to take into account all of constituents of source of draught with different variants of ventilation.
