    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 winzeor a sub-shaft.

    Drifts/Inclined Shafts. The angle at which a drift becomes an inclined shaft is somewhat subjective, but there is some agreement that anything above 30 o to the horizontal is a shaft, not a drift.. A major advantage of drift or inclined shaft access versus vertical shaft access is the ability to move large volumes of equipment, materials and personnel in a properly designed
