mining block depends among other factors on its metal content metal prices and foreign exchange rates. In conventional open pit planning block values are estimated using a single point estimate of metal content ore grade a fixed flat metal price and a fixed exchange rate for example Caccetta and Giannini 1988; Ramazan 2007.
Jul 24 2012 The most common surface mining methods such as strip mining open pit mining opencast mining and quarrying start from the earths surface and keep exposure to the surface during the extraction period. Disruption of the surface significantly affects the soil fauna flora and surface water thereby influencing all types of land use.
