Parandalim dhe mbrojtje nga shpërthimi në minierat nëntokë - Sisteme mbrojtëse - Pjesa 1: Struktura e ventilimit rezistente ndaj një shpërthimi prej 2-bar

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

Scope

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.
