mechanized cut and fill mining method

Conventional versus mechanized cut and fill mining ...

2021-4-5  Mechanized cut and fill generally requires slightly wider veins to accommodate jumbos and load-haul-dumps. As you see in our examples, the mechanized model works on the basis of a vein that is 1 metre wider than that for conventional cut and fill. Grade – Ore grades must support the mining method.

REVIEW OF FILL MINING TECHNOLOGY IN CANADA by

mechanized cut-and-fill replaced conventional cut-and-fill. A specific example of the evolution in mining methods is in the recovery of rib pillars between backfilled stopes. In the 1960's undercut-and-fill replaced square set mining and by the late 1970's vertical retreat mining started to replace undercut-and-fill methods.
