In surface mining, the ore is accessed directly from the Earths surface, and contact is maintained with the surface throughout the operation. Underground or subsurface mining is accomplished with the help of tunnels going into the Earth, and does not occur on the surface. Working Principle. In surface mining, the topsoil and bedrock is
Mining Mining Surface mining It has been estimated that more than twothirds of the worlds 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 produced. Openpit
SURFACE MINING Surface mining is done by removing stripping surface vegetation, dirt, and, if necessary, layers of bedrock in order to reach buried ore deposits or surface mining is the process of extraction of minerals by removal of overburden . Overburden
Surface mining, including strip mining, openpit 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..
