Shaft Sinking - an overview ScienceDirect Topics

Conventionally mined rock caverns are underground cavities constructed by using conventional mining techniques (shaft sinking, excavation of cavities by blasting or cutting). Mined rock caverns can be constructed in a certain range of geological formations which need to allow for the construction and operation of large, long-term stable caverns.

Shaft Sinking - an overview ScienceDirect Topics

With underground mining, the objective is to move as little waste rock as possible in sinking shafts or declines and digging tunnels (drives and adits) accessing the orebody as fully as possible. Mining the actual orebody is then generally more selective. Various mining techniques are employed, but open stoping is common.
