Shaft sinking Wikipedia

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 winze or a sub-shaft.

Shaft Mining, Mining Techniques, Underground Mining

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.

In the past decade all of the producers have begun to mine the less attractive UG2 reef because of its cheaper mining costs. This UG2 reef contains significant quantities of chromite with typically a chrome-to-iron (Cr/Fe) ratio of 1.35.

Chromite ore was extracted from open-pit mines reaching depths of approximately 200 meters until 2005. In 2003, underground mining began. The underground mine is accessible either via an incline ramp or a mine shaft. Ore extraction started at level 500, from which the process proceeds upwards towards the bottom of the open-pit.

The choice of location of a vertical shaft in a narrow vein is shown above. Position 1 is favoured because in a dipping vein, the hanging wall is more apt to move into any mining operations than the footwall.. The disadvantage to this position is the increase in length of crosscuts as the shaft gets deeper

possible failure caused by the shaft itself or due to an old closure treatment. For abandoned mine shafts, some problems linked to deterioration of the sealing structure at the shaft head, or movement of backfilling material in the shaft have been observed. It is also common to find mine shaft opened even decades after mining activity.
