The purpose of mechanized cut and fill mining is to safely extract relatively high grade ore from an irregular orebody with minimum dilution. In cut and fill mining, the ore is excavated in horizontal in horizontal slices, starting at the bottom (sill) of a stope and advancing upwards (crown).
Compare Stoping Methods of Mining
It is used frequently as an auxiliary to other methods, as for mining pillars between filled or caved stopes, crown pillars over completed stopes that have been filled, or sections of cut-and-fill stopes where the ground is too heavy to be mined by cut-and-fill. As with cut-and- fill stoping, it does not lend itself to forcing of production.
