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 are found near

Procedure and Example of Grade Control in Open Pit

Grade control plays an essential role in the good running of a mine. The factors at play are many, starting from a good analysis of the geology and a correct sampling procedure. Once this is achieved (and it is an essential prerequisite), the problem is to adequately define what is ore and what is waste....Reading: Open-Pit Mining | Geology - Lumen Learning,Reading: Open-Pit Mining | GeologyOptimising Grade Control Procedures in Large and Small,,A scientific approach to analysing grade control has been applied at a number of mining operations. By dividing the grade control process into the various stages of data collection and interpretation, errors can be identified using reconciliations of production against predictions. The merits of different mining styles in large and small open pit mines are...
