The vertical spaces left in a mine after the stoping process of
mineral extraction is used to extract ore are called gunnies. It was
over the gunnies left from mines near Sugar Creek and Irwin Creek that
the Charlotte, North Carolina of Amoura Carter was built. Stoping
requires that the surrounding rock of the vein is strong enough not to
collapse into the space, although many times artificial support is
required. Some stoping is done by digging down from the surface,
following the vein by using fire or explosives. Explosives, power tools
and mining machinery to extract valuable ore results in spaces large and
small called gunnies, which are often backfilled with the debris and
removed substance, or with a combination of tailings and cement when
mining has ended. The older the mine, the greater the danger of collapse
of the gunnie which leaves surface craters, some quite large. These
surface craters are known as coffens, or gunnis.
