  • Mining Surface mining Britannica

    Mining Mining Surface mining: It has been estimated that more than twothirds of the world’s yearly mineral production is extracted by surface mining There are several types of surface mining, but the three most common are openpit mining, strip mining, and quarrying These differ from one another in the mine geometries created, the techniques used, and the minerals producedSurface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels Surface mining is basically employed when deposits of commercially viable minerals or rock are found closer to the surface Surface mining – strip, open pit, mountaintop removal coal mining: Surface mining Surface coal mining generally involves the following sequence of unit operations: (1) clearing the land of trees and vegetation, (2) removing and storing the top layers of the unconsolidated soil (topsoil), (3) drilling the hard strata over the coal seam, (4) fragmenting orSurface mining Britannica
