In this paper, a hypothetical open pit copper mine is considered, which needs to produce 30 million tonnes of waste and 25 million tonnes of ore based on its annual planning. This mine works 340 days a year, on which the drilling and blasting operations can be carried out. Thus, the time scale of the dynamic model is set as these …

1. Introduction. Since the 20th century, the heights of slopes in open-pit mines have increased all over the world (Zhang et al., 2012).Examples include the Bingham Canyon copper mine, with a slope height of about 1000 m in the United States; the Udachnaya pipe diamond mine, with a slope height of about 600 m in Russia; and …

Mining - Strip, Open-Pit, Quarrying: 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 …
