open pit mining how it works

Strip Mining, Open

The steps in strip mining are similar to open-pit mining. The steps are: The trees and bushes are pushed down through bulldozers. This waste, along with the filth or sand under it, is taken to a close area and dumped. Lots of minute holes are drilled from the rock.

Mining

Mining. The orebody in Kiruna is an inclined slab of magnetite that is around 80 metres wide, four kilometres long and extends at least two kilometres underground. LKAB mines iron ore both above and below ground, in open-pit mines and underground mines. The mining operation produces several million tonnes of crude ore each year, which is.

Open Cut and Underground Mining

Underground Mining is generally used for areas where the mineral seam is too far underground for open cut mining to be of use. A tunnel, called a decline, is created to allow workers and machinery to reach the location of the minerals. Stope mining is used for most hard rock mining of minerals such as copper, silver, lead and zinc.

Mining: Making the Most of Radioactive Caches

Open-pit differs from other types of surface mining, which remove topsoil in strips throughout the mining process. Underground mining calls for venturing deeper into underground mine systems, where miners use shafts or adits (vertical and horizontal tunnels) to move equipment and ….

Basics of an open pit mine

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.

Surface Mining Methods and Equipment

Open pit and open cast methods employ a conventional mining cycle of operations to extract minerals: rock breakage is usually accomplished by drilling and blasting for consolidated materials and by ripping or direct removal by excavators for unconsolidated.

 · Open-Pit Mining Methods. Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping.
