The bulk of the world's minerals come from open pit mines where large volumes of rock must be moved while keeping costs low. Since profit margins depend on cyclical metal prices, optimal mine design and scheduling are vital. Drawing on our world-wide industry experience, we develop practical and workable solutions based on geological, geotechnical, hydrogeological, economic, and environmental

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

Operation designed to extract mineral deposits that lie close to the surface. It is used when the orebody is near the surface and little overburden (waste rock) needs to be removed. Large hole exposes the ore body. Waste rock (overburden) is

Get PriceOpen 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. In a hard rock mine, the bottom of the pit would be the
