Sizing equipment for open pit mining - a review of critical parameters

摘要: AbstractOver the past century, open pit mines have steadily increased their production rate. Larger equipment and new technologies make it possible to mine larger batches of materials in a shorter time. Low commodity prices forced companies decrease unit cost, by using improving productivity. In late 20th with facing low competing strong rivals globally, lower costs ensured survival. As result, geometry mining dramatically size. To date, terms productivity, industry continues adhere 'bigger is better' mentality. There are indications that this strategy may not always be advantageous. This paper will discuss on-going research into understanding effects size on surface mining. The includes investigation mill construction operating costs, design, economic optimisati...
