Explosion prevention and protection in underground mines - Protective systems - Part 1: 2-bar explosion proof ventilation structure

This document applies to air shutter frames and air doors for ventilation structures which are to remain functional after the passage of explosions with overpressures of up to 2 bar.
Ventilation structures are protective systems to provide the ventilation flow after the occurrence of an explosion such that the effects of an explosion on the ventilation system can be limited and adequate possibilities remain for escape and rescue.
NOTE   These structures may be used when ventilation studies indicate that the air flow in the work place would be reduced considerably providing no safe escape for workers in cases where the structure is destroyed. Explosion proof ventilation structures will be individually evaluated for directional stability of ventilation flows and in order to ensure adequate ventilation flows.

Explosionsschutz in untertägigen Bergwerken - Schutzsysteme - Teil 1: 2-bar-Wetterbauwerk

Diese Norm gilt für Blendrahmen und Wettertüren für Wetterbauwerke, die nach Durchlauf von Explosionen mit Überdrücken bis 2 bar funktionsfähig bleiben.
Derartige Wetterbauwerke sind Schutzsysteme zur Sicherstellung der Wetterführung nach Explosionen, so dass die Auswirkungen von Explosionen auf die Wetterführung in Grenzen gehalten werden können und ausreichende Möglichkeiten für Flucht und Rettung bestehen bleiben.
ANMERKUNG   Derartige Wetterbauwerke werden eingesetzt, wenn wettertechnische Untersuchungen zeigen, dass im Falle der Zerstörung des Bauwerks der Wetterstrom am Arbeitsplatz erheblich reduziert wird, so dass eine sichere Flucht für die Belegschaft nicht mehr möglich ist. Die Wetterbauwerke werden einzeln hinsichtlich der Richtungsstabilität der Wetterströme sowie zur Sicherstellung eines ausreichenden Wetterstromes bewertet.

Protection contre l'explosion dans les mines souterraines - Systèmes de protection - Partie 1 : Sas d'aérage résistant à 2 bar

Le présent document s'applique aux bâtis dormants et aux portes d'aérage des sas d'aérage devant rester opérationnels après une explosion provoquant une surpression jusqu'à 2 bar.
Les sas d'aérage de ce type sont des systèmes de protection qui ont pour fonction de garantir la ventilation après une éventuelle explosion, de telle manière que les effets de l'explosion sur la ventilation puissent être maintenus dans des limites spécifiées et que des conditions suffisantes pour l'évacuation et le sauvetage des personnes soient maintenues.
NOTE   Ces sas d'aérage sont installés lorsque des simulations de ventilation ont démontré qu'en cas de destruction de leur structure, le débit d'aérage dans l'espace de travail est considérablement réduit ne permettant pas une évacuation en toute sécurité du personnel. Les sas d'aérage sont évalués individuellement quant à leur aptitude à assurer la stabilité directionnelle du courant d'air et à garantir un débit d'aérage suffisant.
