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

Copper mining is usually performed using open-pit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted into the drill holes to blast and break the rock. The resulting boulders are then ready for hauling; specialized haul trucks, conveyors
