Abstract
The article describes evaluation of natural draft (thermal drop of ventilation pressure) and determination of its direction in a mine. The measurements taken on main mine fan are processed based on the methods of mathematical statistics. The results allow evaluating the natural mine draft at the preset confidence coefficient, and the offered algorithm enables on-line control of mine ventilation.
