a. A method of stoping wherein the wall rock on one side of the vein is
removed before the ore is broken. Employed on narrow veins, less than 30
in (76 cm), and yields cleaner ore than when wall and ore are broken
together.
b. A method of stoping in which the ore is broken down first and then the
waste or vice versa; usually the one which breaks easier is blasted first.
The broken waste is left in the stope as filling, and the ore is broken
down on flooring laid on the fill to prevent admixture of ore and waste.
Resuing is applicable where the ore is not frozen to the walls and works
best if there is considerable difference between the hardness of the ore
and of the wall rocks.
