#0183;#32;Shaft miningalso referred to as shaft sinkingis a type of mining process used to vertically gain access to an underground mining facility. There are many different components which make up the shaft, all of which play a very important role in the mining process.
Shaft Sinking for SmallScale Mining in Africa Steven Rupprecht1 1 University of Johannesburg Small vertical shafts can play a significant role in small scale mining as they represent a quick and efficient method to gain access to veins located 20 to 50 m below surface. Historically, in central Africa, colonials effectively used vertical

As mining became more mechanized in the mid 20th century, the use of trolley or rail cars and vertical hoist systems led to the addition of trolleycarrier and hoistropebased communication systems.
There is nothing called Shaft mining. Shaft sinking is the term for accessing mineral deposits present deep inside the earth. In this process, a shaft is being driven in the middle or side of the ore. in underground mining where the access is thro...
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.
that process is called deep miningquot;. When it comes to design of a mine shaft, there are two options: circular shafts and horizontal shafts (Figure 1, Figure 2). Circular shaft is the most commonly used one. If the shaft should be deep and shaft diameter is supposed to be more than meters, circular shafts are the best choice.
The major issues of underground mining are improper communication, locating miners positioning, and need of an efficient process for disaster relief. shaft communication system,

The Palabora underground mining project is a stateoftheart shaft mining system that will prove to be a benchmark in its field for years to come. An integration of modern technologyboth in application and developmenthas resulted in a shaft system that is intrinsically holistic.
In Europe, mining situation is different depending on country and it is possible to find areas where shafts are all abandoned or in contrary still active. In these two cases, the most important point is to ensure their long term stability and avoid all possible failure caused by the shaft
Shaft mining or shaft sinking is excavating a vertical or nearvertical 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 the top of the excavation is the ground surface, it is referred to as a shaft; when the top
