Open Pit Mining - an overview ScienceDirect Topics

Open-pit mining is probably most advanced because of developments in mining low-grade copper deposits and iron ore. It is suitable for much of the resource if it is done on a large scale and will allow low-cost removal of most of the resource. Research needs include studies of slope stability, dewatering on a large scale, methods of placement of spent shale in the pit, and a plan for location of pits for
