Mining - Underground mining | Britannica.com

Underground mining. When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered.

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.

Cost of Stoping for Underground Mining

T and T represent mines where the stringer-set-and-fill method, using large quantities of timber, is employed under very heavy hanging-wall conditions that require cautious mining. At SS the higher cost is due to the use of considerable square-set stoping in conjunction with cut-and-fill stoping.

Shrinkage stoping - QueensMineDesignWiki

Shrinkage stoping is a mining method used for steeply dipping, narrower ore bodies with self supporting walls and ore. It is an overhand mining method that relies on broken ore being left in the stope to be used as the "working floor" and to support the walls. During the mining cycle, only 30 – 35% of the ore blasted is extracted being equivalent to the swell factor of in-situ ore to ...
