Surface mining planning and design of open pit mining

The first step in designing a dump is the selection of a site or sites that will be suitable to handle the volume of waste rock to be removed during the mine's life. Site selection will depend on a number of factors, the most important of which are: i) Pit location and size through time. ii) Topography. iii) Waste rock volumes by time and source.
