Environmental Code of Practice for metal mines: chapter 2
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.

Similar to open-pit design and planning, the main motivation for long-term production scheduling of sublevel stope mines is maximizing the NPV over the life of mine. The first attempt of this occurred in 1995, when Trout (1995) developed a new mathematical model based on MIP for scheduling optimisation of a sublevel stoping operation in Mount ...
