Abstract
One of the most important parameter in mine ventilation planning is the friction factor (K). Accurate values of friction factors are critical especially when carrying out mine ventilation simulations. No computer simulation of a mine ventilation network is meaningful if the airway resistances are not accurately estimated or measured. The friction factor between the airflow and the lining in an excavation in a typical mine is the aim of this research . This paper describes the measurement techniques and results from friction factor measurements taken during ventilation surveys at various Algerian’s mines with different support systems. A comparison between experimental and numerical values is also presented.
Keywords: Friction factor, résistance, ventilation, simulation, Algerian’s mines.
