1. Open cast mining in which large pits are dug to excavate the ores lying at shallow depths beneath the surface of the earth. Minerals that lie near the surface are also dug out by the process of quarrying. 2. Deep shaft mining in which deep holes are made to reach the ore lying at
Differentiate between open cast mining and shaft mining 2 See answers arc555 arc555 Open cast mining Essentially, overburden is removed, the exposed ore is recovered, and the pit is filled, progressively, by the next tranche of working footprint of an opencast mine like Macraes in Otago would typically be up to 300 ha although
What is the difference between open cast mining and. Minerals that lie at shallow depths are taken out by removing the surface layer, this is known as open cast mining. deep bores called shafts, have to be made to reach mineral deposits that lie at great depths. this is called shaft mining. hope it helps.

Shaft mining or shaft sinking is excavating a vertical or nearvertical tunnel from the top down, where there is initially no access to the bottom.. Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining the top of the excavation is the ground surface, it is referred to as a shaft; when the top

Difference between open cast mining shaft access exists at the bottom of the proposed shaft and ground conditions allow then raise boring may be used to excavate the shaft from the bottom up, such shafts are called borehole shafts.
Mar 20, 2010#0183;#32;Both are forms of surfacemining. Out here in the western states of America, stripmining is largely associated with coal; openpits more with metal mines of various kinds. I know of a small copper mine in Ut and a phosphate mine in northern Ido that kind of operates in the area between the two, however.
This form of mining doesnt require tunnelling into the earth and is a simple method of mining that yields high production rates. The Fimiston Open Pit and the Newmont Boddington Gold Mine are two of the largest openpit mines in the world, measuring over long, wide and 570m deep.
Differences between open pit and underground mining Main Difference. In surface mining, the ore is accessed directly from the Earth''s surface, and contact is maintained with the surface throughout the operation. Underground or subsurface mining is accomplished with the help of tunnels going into the Earth, and does not occur on the surface
