Shaft sinking

Shaft mining or shaft sinking is excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom. Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects. When the top of the excavation is the ground surface, it is referred to as a shaft; when the top of the excavation is underground, it is called a winze or a sub-shaft.

Unit 16 Mine Development Mining and Blasting

Shaft Sinking (Soft Ground) Method: a) Wood/Steel Piling The first set of piles, forming a circle around the shaft site is started at the surface. As the piles are driven down, the ground is excavated, and a circular crib is put in every few feet. In this way the shaft is sunk in a series of short wooden cylinders.

Shaft Sinking Methods: Caisson Method and Cementation
