The method involves both overhand stoping and ore caving. A chamber is
started as an overhand stope from the head of a chute and is extended up
until the back weakens sufficiently to cave. The orebody is worked from
the top down in thick slices, each slice being, however, attacked from the
bottom and the working extending from the floor of the slice up to an
intermediate point. The cover follows down upon the caved ore. Also called
caving by raising; block caving into chutes.
