Abstract

L’invention concerne une installation de ventilation (1) forcée à relais pour assurer la ventilation de plusieurs fronts d’attaque souterrains, basée sur l’interposition d’un plénum (3) entre une ou plusieurs lignes primaires (2) alimentant en air extérieur le plénum (3) à l’aide d’une ou plusieurs unités ventilateurs primaires (Vp) et plusieurs lignes secondaires (4) partant du plénum (3) et prélevant chacune de l’air dans le plénum (3) pour l’amener jusqu’à un front d’attaque respectif par une unité ventilateur secondaire (Vs) montée sur la ligne secondaire (4), la ou les unités ventilateurs primaires (Vp) et la ou les unités ventilateurs secondaires (Vs) étant commandées en débit de façon à obtenir les débits volumiques d’air souhaités aux fins des lignes secondaires (4).The invention relates to a forced ventilation installation (1) with relays for ensuring the ventilation of several underground attack fronts, based on the interposition of a plenum (3) between one or more primary lines (2) supplying air outside the plenum (3) using one or more primary fan units (Vp) and several secondary lines (4) starting from the plenum (3) and each drawing air from the plenum (3) for the fed to a respective leading edge by a secondary fan unit (Vs) mounted on the secondary line (4), the primary fan unit(s) (Vp) and the secondary fan unit(s) (Vs) being flow controlled so as to obtain the desired volume flow rates of air at the ends of the secondary lines (4).
