Open-pit mining Britannica

Deposits mined by open-pit techniques are generally divided into horizontal layers called benches. The thickness (that is, the height) of the benches depends on the type of deposit, the mineral being mined, and the equipment being used; for large mines it

Open Pit Mining IntechOpen

Oct 08, 2019 Open pit mining is defined as the method of extracting any near surface ore deposit using one or more horizontal benches to extract the ore while dumping overburden and tailings (waste) at a specified disposal site outside the final pit boundary. Open pit mining is used for the extraction of both metallic and nonmetallic ores.

Open-Pit Mining Definition Anglo American

Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Open-pit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. This surface mining technique is used when mineral or ore deposits are

Surface mining Wikipedia

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

Digging deeper: Mining methods explained Anglo American

Open-pit is one of the most common mining methods used and starts from the earth's surface, maintaining exposure to the surface throughout the extraction period. The excavation usually has stepped sides to ensure the safety of the miners and a wide ramp where equipment can travel, allowing the product to be removed efficiently from the site.

is similar to open-pit mining. It is used to collect mineral deposits that are close to the surface in horizontal beds. In strip mining, the overburden is removed, and then lots of small holes are drilled in the rock just over the ore. Explosives are then placed in the holes to break up the rock so that it is easier to find the mineral.

There are several different ways to mine underground. You can build spiral tunnels that circle the deposit, sink vertical shafts adjacent to the ore, or create adits, which are horizontal excavations into the side of a hill or mountain. Unlike open pit, underground mining requires that you take into account a wide variety of added requirements
