How does a surface miner work?
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through …
What is strip mining in business?
Strip mining, removal of soil and rock (overburden) above a layer or seam (particularly coal), followed by the removal of the exposed mineral. Such spoil areas are now routinely reclaimed and permanent vegetation reestablished as an integral part of surface-mining operations.
Which of the following equipment is used in mines?
Underground specialized mining equipment such as trucks, loaders, diggers etc. are used to excavate the material and are normally hauled to the surface with skips or lifts for further processing. Drilling is normally required to place explosive charges to liberate the minerals from the overburden material.
What are the disadvantages of strip mining?
Strip Mining Cons to Consider. 1. It requires an investment gamble. The processes of strip mining are cheaper. The actual investment into those processes, however, are typically higher than in other forms of mining. From equipment to staffing to distribution, it may not always be possible to gain an exit out of this investment.
What is the cause of strip mining?
Usually, it is because of the mining of fossil fuels or other precious stone or mineral. When it comes to extracting coal, underground mines and strip mines, or otherwise known as surface mines, are the two techniques at our disposal. Both are damaging, but strip mines, which represent 40% of the world’s mines, are the most damaging of the two.
What are the steps of strip mining?
The steps in strip mining are similar to open-pit mining. The steps are: The trees and bushes are pushed down through bulldozers. This waste, along with the filth or sand under it, is taken to a close area and dumped. Explosives are put in the holes and blazed. This breaks up the rock which is taken to the dumping area.
Why is strip mining used?
Strip mining is a form of surface mining that is usually employed for the recovery of materials such as coal and tar sand, which are relatively near the surface of the earth. Surface vegetation, soil, and rocks are removed in strips, often in conjunction with controlled explosions, to make removal more efficient.
