Vertical shafts play an important role in the safe operation of mines. The stability of vertical shafts has always been a difficult problem in mining engineering, especially with the increasing of mining depth. In order to keep the engineering works stable, it is necessary to make the deformation failure mechanism of vertical shafts clear. This paper describes a case study of the deformation ...

Shaft mining synonyms, Shaft mining pronunciation, Shaft mining translation, English dictionary definition of Shaft mining. n. A vertical or sloping passageway made in the earth for finding or mining ore and ventilating underground excavations.
Some of the development components of an underground mine are illustrated in the figure. Vertical openings shafts and raises. The principal means of access to an underground ore body is a vertical opening called a shaft. The shaft is excavated, or sunk, from the surface downward to a depth somewhat below the deepest planned mining horizon.
