Stope

In the
mine there are 'foot walls' and 'hanging walls'. On the
foot wall, the ore looks like it is lying. On the hanging wall,
the ore looks like it is hanging out or down.
To 'stope' is
to mine the ore between the hanging wall and foot wall from level to
level.
'Shrink stope' is a method of mining in which 1/3 of
the ore is taken out while 2/3 stays in the stope for staging. |
