Overview of Underground Metalliferous Mining | SpringerLink

A mine should have minimum two primary access. Sometimes, tertiary access is also made as chute, ore pass or manway. The overview of different access to an underground mine is shown in Fig. 2.1. Once the access to the mine is made, the excavation of the orebody is carried out. The ore extraction takes place using different stoping methods.

Understanding Underground Mining Methods

The three main types of underground mining are room-and-pillar, cut-and-fill, and block caving. The process of underground mining is aimed at ensuring safety, economic viability, and minimal waste. Access to an underground mine can be via a horizontal or vertical tunnel, referred to as an adit, shaft, or decline.

Underground Mining – Prisma Training Solutions

Underground mining courses Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies.

The stages of mining: 5 lifecycle processes explained

Development of the mine itself is different for an open pit to an underground mine and will require different experience and equipment. Porphyry deposits are often large and many of the deposits are near the surface and mined as open pits with large mining equipment; however, at depth some may have suitable characteristics to convert to large ...

Underground Mining Methods

Sublevel stoping is a mining method in which ore is blasted from diferent levels of elevation but is removed from one level at the botom of the mine. Before mining begins, an ore pass is usually drilled from a lower to a higher elevation. Jumbos selectively drill holes into the roof of the drift and fill them with explosives.

Beginners Guide to Stope Mining

Once the area is surveyed and mining engineers develop plans for the underground mine, construction will begin. The shaft, a vertical tunnel used to move from the surface to different levels of the mine, is created.. By drilling holes and inserting explosives inside, miners blast openings into the rock.

Back - The ceiling or roof of an underground opening. Backfill - Waste material used to fill the void created by mining an orebody. Background - Minor amounts of radioactivity due not to abnormal amounts of radioactive minerals nearby but to cosmic rays and minor residual radioactivity in the vicinity. Back sample - A rock sample collected from the roof or …

Coal Mining and Processing Methods

Underground mining is usually by the room-and-pillar mining or longwall mining method . Even in mines where the longwall method is the principal extraction method, the development of the mine and the longwall panels is accomplished by room-and-pillar continuous mining. ... Different cleaning processes are used on different sizes of coal ...

Differences Between Surface and Underground Mining

Surface mining occurs on the Earth's surface, where minerals and resources are located close to the topsoil. Underground mining, on the other hand, involves creating tunnels and shafts to extract resources buried deep beneath the surface.

The method to be used for underground mining depends on the concentration of ore, strength of the surrounding rock, and the various risks involved. ... In this mining technique, a series of horizontal tunnels, or sub-levels, are excavated one above the other, to access different levels of a vertical ore deposit. At the bottom of the stope is a ...

The Environmental Impact of Mining (Different Mining …

Some mining techniques — like in-situ leaching, which uses acid and water to remove minerals from a site without significantly disturbing the surface — have much less environmental impact. In-situ mining techniques can use less water than open-pit mining and underground mining, and also reduce the risk of releasing ore dust into the atmosphere.
