    Open-pit mining Wikipedia

    Open-pit mining, also known as open-cast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an open-air pit, sometimes known as a borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.Open-pit mines are used when deposits of commercially useful ore or rocks

    Open-pit mining occurs on surface and is generally the cheapest way to extract ore. This is because rock doesn’t have to be moved far up hill against gravity, equipment used can be larger than underground, and it doesn’t require more expensive features like ventilation, communications, etc. that underground does.

    Basics of an open pit mine Mine Engineer.Com

    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.

    What are the different types of mining and how do they

    Open-Pit. As the name suggests, open pit mining involves mining minerals or ore that can be found near the surface layer of the site. That being said, some quarries can be over 1000 meters deep. This form of mining doesn’t require tunnelling into the earth and is a simple method of mining that yields high production rates.

    Green Mining Massachusetts Institute of Technology

    Although open pit mining (link to mining solution page) contributes about 85% of all mineral mining, it is one of the most environmentally taxing. About 73% of extracted rock goes to waste. Meanwhile, underground mining wastes only 7% of the extracted rock but is more expensive (Hartmann and Mutmansky, 2002).

    The Hidden Dragon: Nitrate Pollution from Open-Pit Mines

    elemental Nitrogen, the practice of open pit mining can lead to nitrification of shallow aquifers (Zaitsev,Mettänen, and Langwaldt, 2008). Similar to the processes leading to high sulphate concentrations in water, elemental nitrogen can be released as nitrate during excavations for mining, especially into local groundwater resources.

    Environmental Risks of Mining

    Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

    Environmental Consequences of Open Pit Mining

    An open pit mine is a type of excavation where surface and subsurface materials (soil and rock) are removed, typically through use of explosives and mechanical mining and hauling equipment, to gain access to commercially valuable ores or other buried natural resources, including coal and gemstones, that are relatively close to the surface.
