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.

A mine shaft is a is a vertical access hole that is several meters in diameter and stretches down to the location of the ore. It is where miners, supplies, equipment, water and air are conveyed to gain access to the ore. Ore is conveyed to the surface through mine skips that move up and down the shaft.

The shaft is equipped with elevators (called cages) by which workers, machines, and material enter the mine. Ore is transported to the surface in special conveyances called skips. Shafts generally have compartments in which the media lines (e.g., compressed air, electric power, or water) are contained. They also serve as one component in the overall system of ventilating the mine.

 · The establishment of an air shaft is essential to any type of mining that requires workers to be underground. The establishment of an air shaft is extremely important to any type of mining operation that requires humans to actually go underground, such as in a coal mine. Usually, an air shaft is drilled into the tunnel, creating a vertical .

The ventilation system for the shaft-sinking operation used refrigerated air to cool the miners as they worked. That system, however, was designed for hot rock, not hot water. “As a result of the heat load coming into the shaft, we have had to suspend shaft-sinking operations and upgrade the ventilation by as much as three times,” Goodell said.

Underground mining is used when the deposit is too deep for surface mining or there is a restriction on the use of the surface land. The deposit is accessed from the surface by vertical shafts, horizontal adits, or inclines . The deposit itself is developed by criss-crossing openings (called levels, cross-cuts, raises, etc.) in the orebody, not only to create blocks of ore to be extracted according to a …

 · In most shaft mining practices, the shaft will be split into different sections. Each section is vertical, as they run parallel to the service cage. In most shaft mines, most of these sections are used for lifting purposes. The service cage itself usually contains a large elevator, which is used to transport mining personnel up and down the .

 · Well, yes and no. From the ninth century AD (though the historians are still uncertain about the exact date of its invention) to the mid-1800s, black powder was the only explosive available. A single type of explosives was therefore used as a propellant for guns and for blasting purpose in any military, mining and civil engineering application.
