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 - Systemes de protection - Partie 1 : Sas d'aérage résistant a 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.

Overview

EN 14591-1:2004 - published by CEN - defines requirements for 2-bar explosion proof ventilation structures used in underground mines. The standard applies to air shutter frames and air doors designed to remain functional after the passage of explosions with overpressures up to 2 bar, enabling continued ventilation, escape and rescue operations following an explosion.

Key topics and technical requirements

  • Scope and purpose: ventilation structures as protective systems to limit the impact of explosions on mine ventilation flow and to preserve escape and rescue routes.
  • Design loads: verified performance for explosions up to 2 bar overpressure.
  • Materials: use of non-combustible, underground-approved components; hydraulically bonded materials with a specified minimum tensile bending strength (7-day value).
  • Air shutter frames:
    • Minimum frame length calculated from the standard equation.
    • Set into strata with an all-round depth of at least 250 mm; yielding compression inserts permitted to absorb strata movement.
    • Rib thickness requirements provided in tabulated form depending on roadway cross-section.
  • Air doors:
    • Two types: pressure-relief travel way doors (designed to open with the pressure wave) and non-pressure-relief haulage way doors (designed to resist and stay closed against the wave).
    • Door leaves must allow simultaneous opening up to 90°.
    • Sealing bars must be hardly combustible and antistatic (referencing EN 13478 and EN 13463‑1).
    • Examples of verifiably tested constructions are given in Annex A (travel way door - a = 700 mm, h = 1 800 mm) and Annex B (haulage way door - a = 1 600 mm, h = 2 000 mm).
  • Control systems: control lines and actuating contacts must be protected from explosion effects and must not be triggerable by the blast pressure wave.
  • Marking: doors must be permanently marked with year of manufacture and manufacturer’s stamp in accordance with Directive 94/9/EC (ATEX-related).

Applications and who uses it

  • Target users: mine safety engineers, ventilation designers, equipment manufacturers, installation contractors, and safety assessors working in underground coal and metal/non‑metal mines.
  • Practical uses:
    • Specifying and procuring explosion-resistant air doors and shutter frames.
    • Designing ventilation regulators and airlocks to preserve post‑explosion ventilation flow.
    • Performing compliance checks and static verification when dimensions diverge from tested examples.
    • Integrating ventilation protective systems into mine safety and emergency response planning.

Related standards and references

  • EN 10025 (structural steels)
  • EN 13463‑1 (non-electrical equipment for potentially explosive atmospheres)
  • EN 13478 (safety of machinery - fire prevention)
  • ISO 2768‑1 (general tolerances)

EN 14591-1:2004 is essential for ensuring ventilation safety and explosion protection in underground mining environments where maintaining airflow after an explosion is critical for evacuation and rescue.

Frequently Asked Questions

SIST EN 14591-1:2005 is a standard published by the Slovenian Institute for Standardization (SIST). Its full title is "Explosion prevention and protection in underground mines - Protective systems - Part 1: 2-bar explosion proof ventilation structure". This standard covers: 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.
