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

[] Reconciliation principles for the mining industry

Abstract Reconciliation involves the collection of tonnage, grade (quality) and contained metal (product) data from disparate and hopefully independent sources. Examples are exploration data, production sampling data from blast holes or draw points, and process plant data. These data may be compared by means of ratios (factors). The F1 factor usually relates short term (ore control) model
