    • Abstract:
      The basic linear resistance is often applied to the resistance systematization as the specific resistance of a 100 meter length of an underground ventilation airway. In standard environment the characteristics of such specific resistance are influenced by the room dimensions and relative roughness value that includes hydraulic friction factor of the airway. To determine the specific resistance value, the calculation results obtained after measurements in situ in the mine in question are herewith analysed. For approximate determination the nomogram in Fig. 4 of this paper can be used (the paper is published in Croatian).
