Strip Mining. Strip mining is a kind of surface mining. The ore is very near to the surface of the land but has one or more layers of rock and filth on top of it. To mine the ore, these layers have to be removed. The steps in strip mining are similar to openpit mining.
The majority of open pit mines in Australia currently operate using discontinuous shovel/truck systems. These systems are favoured as they enable; (i) mining capacity to be progressively scaled up over the life of a mine; (ii) the use of narrow benches that defer the high costs of stripping, and (iii) flexibility to rapidly adapt mine plans in the face of uncertainties caused by changing ...

The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also in operation around the globe. The decision for employing surface mining or underground mining is dependent on the proximity of the ore body to the surface.
When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This equipment can include the following: Draglines which ...
Open Pit Mining. Open pit mining, also known as strip mining, is the removal of surficial soils and uneconomic rock to get at the ore below. Ore grades are normally less than %. This is type of mining is only possible if the uranium ore is near the surface (normally less than 400 ft).
The mining area is literally shaped like a pit that can hold equipment and workers. Terrace Mining. Terrace mining is similar to openpit mining in that a large hole is dug as deep as 12 meters. In the terracemining method, though, steps or "benches" are created parallel to .
Mining Fleet Achieves 100,000 Hours and Beyond. FreeportMcMoRan Copper and Gold's Sierrita openpit mine is a lowgrade copper operation located in southern Arizona, USA, some 48 kilometers (30 miles) north of the Mexican border.
Openpit mining involves removing the layers of sand and rock found just above the kimberlite. Once exposed, the ore in the pit is broken up by blasting. A single blast can break approx. 3,000 tonnes of ore. Once the ore is broken, excavators load the ore into haul trucks and transport it to a primary ore crusher where the diamond extracting ...

Bingham Canyon Mine, located near Salt Lake City, is the world's deepest manmade open pit excavation. The mine is miles (4,5km) across and mile (1,2km) deep. Since mining operations started in 1906, Bingham Canyon Mine has been the granddaddy of all copper mines.
