Opencast mine equipment selection using genetic algorithms
The excavating and haulage equipment selection to remove the overburden in an opencast mine is an essential and complex decision that requires Mining and Mineral Processing 3.1 Opencast Mines Opencast mining is extraction of commercial minerals from the Earth’s surface using open-pit workings. About 60 % of metallic ores, 85 % of non-metallic ores, 100 % of non-metallics, and 35 % of coal are produced by this method. The distribution of mineral resources of the world is shown Chapter 3 Mining and Mineral Processing Springer
