Underground Mining and Its Methods

Cut and Fill. It is a short-hole mining method, used in ore zones that are irregular or steeply dipping. The ore is dug out in slightly inclined slices or horizontally. And sand will fill it, waste rock, or tailing. This method is a selective and expensive one. It has the advantages of low ore dilution and loss.
