Stoping | mining | Britannica

Stoping is practiced in underground mineral mining when the surrounding rock is strong enough to permit the drilling, blasting, and removal of ore without caving. In mines where the rock requires no artificial support, the operation is known as open stoping.

OPTIMIZATION OF MECHANIZED MINING LAYOUT WITHIN

Create focused mining on primary development from the production stoping, thus having Anglo American Platinum currently has underground mechanized mining methods at a small percentage of its mines. These methods are: • Bord and pillar (1.8 m–2.2 m stope widths using low-profile (LP) mechanized equipment) • Breast mining (1.3 m stope width using extra-low profile (XLP) mechanized

Major Mines & Projects | Zimplats Mine

At Rukodzi and Ngwarati mines, the broken rock is loaded onto trucks by LHD and trucked to a surface crusher while Mupfuti and Bimha mines have underground crushing plants and ore is tipped into the crusher and conveyed to surface. The production target for each fleet varies from 16 000t in the Upper Ores I and more than 21 500t of ore per month, in the flats depending on the particular mine

Stillwater and East Boulder Platinum and Palladium Mine

The shallow to intermediate level underground platinum and palladium mines are located within the Custer and Gallatin national forest and near the Nye and McLeod towns. Stillwater and East Boulder mines were initally operated by Stillwater Mining Company, which was acquired by Sibanye-Stillwater for $2.2bn in May 2017. The annual production from the Stillwater mine is approximately 380,000oz

Underground mining (hard rock) Wikipedia

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. Soft rock mining refers to excavation of softer minerals such as salt, coal

Shrinkage stoping QueensMineDesignWiki

Shrinkage stoping is a mining method used for steeply dipping, narrower ore bodies with self supporting walls and ore. It is an overhand mining method that relies on broken ore being left in the stope to be used as the “working floor” and to support the walls. During the mining cycle, only 30 – 35% of the ore blasted is extracted being equivalent to the swell factor of in-situ ore to

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

Optimisation of a Mechanised Platinum Mining Section

The introduction of Extra Low Profile (XLP) mechanised equipment within Anglo Platinum is an important strategy to improve safety and minimise the cost of their mining operations. The purpose of this project is to analyse and improve the XLP section’s production performance at Waterval Central Shaft. In this project the XLP section is considered to be a business unit which forms a small but

Underground Mining, Underground Mining Equipment

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. The mining company selects the best feasible way to get the minerals extracted out.
