Overburden management in open pits: options and limits in large
The exploitation requires the removal and disposal of about 50 million cubic metres (Mm3) of overburden material during the 20-year quarry lifespan. Limestone deposit is covered by a 50–70 m thick layer of soil–clayey sand and clay–which has to be removed by means of excavators/shovels and chain bucket excavator.
