Jet engines are used for mine rescue in our non-Hungarian neck of the woods. https://www.rnz.co.nz/news/pike-river-2010/66373/pike-river-gag-unit-to-be-handed-

  This is pretty awesome (in addition to this whole thread).

  For mine rescue? These seem designed to put out fires by suppressing O2 levels. Is this helpful in rescue situations or are these more about simply putting out stubborn underground fires?

    Sometimes you have to put out the fire that's trapped the miners before you can rescue them.
