Open Cut Mining Ppt Pit Design
open cut mining ppt pit design
Open pit mine design is a multistep process applied to determine a number of technical parameters and the design of a number of aspects of the operation. In that process, cutoff grade is the most significant aspect, as it provides a basis for calculating the quantity of ore and waste in a given period.

Green Mining
Although open pit mining (link to mining solution page) contributes about 85% of all mineral mining, it is one of the most environmentally taxing. About 73% of extracted rock goes to waste. Meanwhile, underground mining wastes only 7% of the extracted rock but is more expensive (Hartmann and Mutmansky, 2002).

Abstract: De Beers is currently developing closure plans for two open pit mines. At first glance they appear quite similar; both are relatively remote, have operated for 10 years, have similar pit dimensions (250–300 m deep and km wide) and have Palaeozoic sedimentary host lithologies with weak upper units overlying more competent lower materials.

Open Pit Mining
Openpit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow. Figure Openpit mine [16]. Surface mining is usually used to develop coal seams and deposits of many other minerals, but their feasibilities vary with the nature of the body ore.
