Open Cut Mining. There are many differences between open cut and underground mining. When minerals and deposits are found close to the surface and spread across a large distance, the best way to mine is to use the open cut mining method. In this process, the area is cleared of all topsoil and vegetation, this material is stockpiled and used ...
DISADVANTAGES OF THE SHRINKAGE STOPE. In a shrinkage stope, after mills have been made, the orebody is undercut. By setting up the machines on the broken ore and working around the perimeter of the stope, its height is increased until the top of; Open Stope Mining Method. the deposit is reached.
Rill-Cut Stoping Mining. Rill cut, or rill stoping, as shown at B, Fig. 2, has the principal advantage that when filling is used it can be run down through a raise at the apex of the stope and will fill the stope without shoveling. Its disadvantages, on the other hand, are as follows:
Advantages of Underground Mining are: * It allows minerals to be extracted from deep underground * It doesn't create a mess like open cut or surface mining * Does not affect the physical ...
Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.
Opencast mining is also known as open-put mining, open-cut mining, surface mining and also as strip mining, the later term being commonly used in the U.S.A. for opencast mining of coal. The overburden and the mineral, coal, are excavated in long strips of a few metres thickness and hence the operations are termed strip mining.
The open pit mining method (also known as opencast, open-cut, or strip mining) is not extractive; meaning that most of the time there no need to tunnel directly into the earth. Rather, it is a technique used when rocks and/or ore are discovered near the surface.
