Abstract (en)
The present invention refers to an ultrafast insulation device for mining galleries, operating automatically, for delimiting and securing fresh air circuits from areas contaminated by burned gases, toxic and/or explosive gases, produced as a result underground events such as explosions fires. The ultrafast gallery insulation device is automatically triggered by an explosion overpressure sensor (6) or by an infrared radiation sensor (5), activating the pyrotechnic gas generator (4) which expels the shutter from the storage block (1) with subsequent inflation against the walls of the gallery. The shutter's central membrane (8) is provided with zipper (9) allowing the passage of workers.
