Underground Mining Methods — New Pacific Metals

This bulk underground mining method involves mining large amounts of material from a single stope – similar to cut and fill, this method starts at the bottom of a level and moves upward. Ore is removed from the bottom, and then more ore is blasted from a higher level that falls to the same level to be removed, with the process repeating up the orebody.
