Dear All,
If you haven't seen this it's worth looking at as (as the person who put it
up says), it's the only chance/way to see what an underground stope blast
looks like (longhole anyway). Look closely and you can see the sub levels, and
also that the ore is falling to a lower level ore bin. This opencast is
developing into a glory hole by this process - a technically interesting piece of
film.
Being very Pol.Crct.(!), Compliments of the Season to All on the List.
Regards, Bernard
