What is the difference between open cast mining and shaft mining Class 8? Minerals can be extracted by mining, drilling or quarrying (Fig 3.3). 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 …

difference between open cast mining, shaft mining and drilling Share with your friends. Share 2. 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.

Answer: Open cast mining-. Essentially, overburden is removed, the exposed ore is recovered, and the pit is filled, progressively, by the next tranche of overburden.The working 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 …

Opencast mining or quarrying of minerals is easier than mining by underground methods. During quarrying the alluvium and rocks below which the minerals lie, are removed and dumped, in the initial stages, in a place which is not required in future for quarrying, residential or other purposes. The mineral exposed is completely extracted. Opencast ...

Open cast mining. Open cast mining is also known as strip mining and is used for bedded deposits, and most commonly for coal. Although it is similar to open pit mining, the distinguishing characteristic is that the overburden is not hauled away to waste dumps; but rather, it is immediately cast directly into the adjacent mined-out cut.
