Shaft sinking - Wikipedia

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 …

Shaft Mining. Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earth's surface. It is found mostly all over the world. Shaft sinking refers to shallow shafts and it is different from a deep shaft. The …

Shaft vs. Ramp Access - QueensMineDesignWiki

Shaft access can also be utilized through an internal shaft, or a winze. This type of access is most commonly utilized in the case of deep lenses that extend past the initial mine life. The top of the winze is located underground and usually offset from the initial mode of access in order to get access to deeper pockets of the orebody. The development of a winze can differ slightly from that of a conventional …
