Abstract
Air resistances are classified depending on their locality in underground mines. Three groups of local resistances are distinguished: shaft and mining horizon intersections; shaft and air channel intersections; stope and ventilation duct intersections in blind drifts. Influence of each group of the local resistances on the mine depression is evaluated as function of geometry and aerodynamics of underground openings. The criteria are proposed for estimating percentage influence of each group on the total mine depression are proposed. The calculation methods are determined for each group to be advisably used in quantitative analysis of air distribution in underground mine ventilation networks under the ventilation mode change.
