May 13, 2019 Advantages of deep shaft coal mining. The advantages of open pit mining sciencing. mar 13, 2018 open pit mining does offer some advantages over traditional deep shaft mining. pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly. the working conditions are safer for the miners because there is no risk of cave in or toxic.
Apr 03, 2018 Differences between open pit and underground mining. -Higher productivity. Greater concentration of operations and easier management of human and material resources. High mechanization, there are no limitations for the size of the machines. -Flexibility to respond to increases in demand. Higher production per mine.
Differentiate between open cast and shaft mining Open cast miningEssentially, overburden is removed, the exposed ore is recovered, and the pit is filled, progressively, by the next tranche of overburdenThe ing footprint of an opencast mine like Macraes in Otago would typically be up to 300 ha although the total area mined over time would be much greater than that Shaft mining

Oct 10, 2016 Strip mining is done on the surface underground mining is done below the surface. In strip mining, the ore is extracted from the surface in layers resulting in a deepening artificial valley. This is done when the ore is relatively near the surface. In underground mining, mine shafts are bored or dug from the surface to the underground layers where the ore is located, and ore extraction takes ...
What is open pit mining . Open pit mines are those mining operations that take place on the surface , unlike the underground mines. This is possible when the reservoir sprouts on the surface or at a very small depth. It began to be realized in the middle of the XVI century and it is used all over the world.
