Suglo 1 CUT-AND-FILL STOPING METHOD In cut-and-fill mining the ore is excavated in horizontal slices, starting from the bottom of a stope and advancing upwards. The blasted ore is loaded and completely removed from the stope. When the full slice has been excavated, the corresponding volume is filled with waste material.

Underhand cut and fill QueensMineDesignWiki

Geological Setting. Underhand cut and fill is a versatile mining method; it can be used in orebodies of varying widths and dips, from vertically dipping to flat lying.It is most useful in ore where the wall rock or vein is unconsolidated and cannot be safely mined using traditional cut and fill.Underhand cut and fill has been particularly successful in rockburst-prone areas.
