Strip mining Britannica

Strip mining, removal of soil and rock (overburden) above a layer or seam (particularly coal), followed by the removal of the exposed mineral.. The common strip-mining techniques are classified as area mining or contour mining on the basis of the deposit geometry and type. The cycle of operations for both techniques consists of vegetation clearing, soil removal, drilling and blasting of

Strip Mining an overview ScienceDirect Topics

Strip mining process is most suitable for fairly flat shallow single-seam coal, lignite and other bedded deposits. The mineral layer is covered by an even thickness of overburden composed of soft topsoil and weathered rocks in succession. The soft and unconsolidated overburden can be stripped and removed either by dragline or shovel to expose a coal seam and certain metallic ores. The

Strip Mining, Open-pit Mining, Surface Mining, 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. Lots of minute holes are drilled from the rock that is above the coal or mineral bed [vein] Explosives are put in the holes and blazed. This breaks up the rock which is taken to

Surface mining Wikipedia

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 shafts or tunnels. Surface mining began in the mid-16th century [dubious

What Is Surface Mining? Convergence Training

Strip mining is the process of removing a thin strip of overburden (earth or soil) above a desired deposit, dumping the removed overburden behind the deposit, extracting the desired deposit, creating a second, parallel strip in the same manner, and depositing the waste materials from that second (new) strip onto the first strip. And so on.

Strip mining Academic Kids

Strip mining is the practice of mining a seam of mineral ore by first removing all of the soil and rock that lies on top of it (the overburden).It is similar to open-pit mining in many regards. Strip mining is also used to extract the oil-impregnated sand in the Athabasca Tar Sands.. Strip mining is only practical when the ore body to be excavated is relatively near the surface.

Returning Mined Land to Productivity Through

Each coal mine has a limited life span due to the finite nature of the resource being extracted. Eventually the resource is exhausted, or the point is reached at which it is no longer profitable to extract for any number of reasons, such as increasing mine depth, increasing strip ratios, changing regulations, or market pressures.

Open-pit mining Wikipedia

Open-pit mining involves the process of disrupting the ground, which leads to the creation of air pollutants. The main source of air pollutants comes from the transportation of minerals, but there are various other factors including drilling, blasting and the loading and unloading of overburden. These type of pollutants cause significant damage to public health and safety in addition to
