In many ways, excavating concepts have changed little since the introduction of the first steam shovels into mining in the late 1800s. And, while that was revolutionary in terms of how mines were designed, and the types of orebody that could be mined profitably, developments that have come since have essentially been focused on the technology used rather than the concepts. Rope shovels and draglines, the key mining machines up to the 1970s, were then joined by the first generation of large hydraulic excavators -- some of which worked, while others did not. Today, the market for mining excavators is wider than it has ever been, with continuous cutting technology having been transferred successfully from the construction industry. What is more, manufacturers are now pushing the boundaries with systems that have been confined to soft-rock applications, bringing closer the possibility of high-volume continuous production in harder material.
