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.

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.

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.

In stark contrast to surface mining, underground mining ventures deep beneath the earth's surface to extract valuable minerals and ores. This method is favored when deposits lie at considerable depths or when surface conditions pose significant challenges to extraction.

Underground Mining Methods

Mining now proceeds underground, underneath the open pit. At first, both a raise and a network of tunnels are made. At different sublevels, jumbos are used for long hole drilling, drilling directly upwards into the roof.

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 ...
