  • On the Dynamics of Mining Operations in Open Pit Mines

     · In this paper mining dynamics is defined as the relationship between the mining rate and movement of mining operations conducted on the benches of a surface mine. This relationship describes the intensity of the pit development in space in order to meet ore demand at the mill over time.

    MiningMiningSurface mining It has been estimated that more than two-thirds of the world s yearly mineral production is extracted by surface mining. There are several types of surface mining but the three most common are open-pit mining strip mining and quarrying. These differ from one another in the mine geometries created the techniques used and the minerals produced.
