About this document

Open Pit Mining Overview and Techniques by Mirko Cuaquira is a document available to read on EtoBox.

Open pit mining involves systematically removing overburden and extracting ore from a series of stepped benches to maximize slope stability and productivity. As the pit deepens, waste is removed from upper benches and transported to dumps while ore is processed. Eventually the stripping ratio makes further mining uneconomical. Key factors in open pit design include establishing pit limits based on the economic stripping ratio, and developing stripping strategies like declining, increasing, constant, or phas
