steps involved in underground mining

Mining - Underground mining Britannica

Mining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the ...

What is Underground Mining? (with pictures)

2020-12-11  Underground mining is a technique used to access ores and valuable minerals in the ground by digging into the ground to extract them. This is in contrast with techniques like open pit mining, in which the surface layers of ground are scooped away to access deposits, or mountaintop removal, in which the top of a mountain is simply shaved off to access the ore inside.

Stope mining Britannica

Other articles where Stope is discussed: mining: Underground mining: of extracting ore are called stopes or rooms. There are two steps involved in stoping. The first is development—that is, preparing the ore blocks for mining—and the second is production, or stoping, itself. Ore development is generally much more expensive on a per-ton basis than stoping, so that every effort

The Mining Process – Waihi Gold

Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers. Dump trucks haul the rock to the primary ...

How Underground Mining Works HowStuffWorks

Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.

Underground mining – block caving, bore hole, drift

Underground mining is carried out when the rocks, minerals, or precious stones are located at a distance far beneath the ground to be extracted with surface mining. To facilitate the minerals to be taken out of the mine, the miners construct underground rooms to work in.

Digging deeper: Mining methods explained Anglo

The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.
