INTRODUCTION. In open-pit mining, there is a clear trend of excavating mines of increasing depths (Figure 1a).Owing to the increased efficiency of mining equipment and improved exploration techniques and technology, the ore bodies left to be exploited are deeper (Figure 1b).The deeper a mine is, the higher the effect of pitwall …

mine [10,11]. As open pit mining operations mature and additional resources are discov-ered, extensions to mine life are common. This results in greater pit depths and thus longer hauls. Ultimately, the cost of material transportation takes a larger and larger share of the operational costs of the site [6,11]. For this reason, one of the ...

Open pits are generally much wider than they are deep to ensure the stability of the pit walls (see Figure 2.3). The stripping ratio (the ratio of waste rock to ore) varies dramatically over the life of an open pit mine and depends on the geometry of the ore body, ore grades, slope stability, site geology, and variations in the price of the metal.

Open-pit mining technology. Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.

1.1.3.1 Open-pit mining Open-pit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden. The
