slight modification. Vertical walls of buildings have vertical compression and horizon-tal tension due to potential wind loads. Since the lining would have horizontal com-pression, the requirements must be flipped. Similarly, it may be interpreted that the shaft lining is a compression member requiring minimum 1% reinforcement. This is

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 ...

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.
