I remember my first experience of air doors at Ashington underground training gallery. 'Right Lads' the instructor said, " Wa ganna cut through here to the supply road, it's a bit drafty so hing on te ya hats"..... he opened this sliding door which was about 2 foot square and 2 foot off the ground...Woosh! this open door must have been a direct short to the full pressure mine ventilation between intake and return air.. you could feel yourself being sucked towards this hole, it pulled your hat off and you got blasted through, you were lucky if you could keep on your feet.

I think it was the instructors way of having a good laugh, watching our surprised and shocked expressions.

The serious point he was making was of course to highlight potential danger around doors in some areas of the mine.
