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
Traditional surface mining has left untold tons of minerals underground, simply because there was no way to get to it safely and efficiently. The Vermeer innovative Terrain Leveler ® surface excavation machines can work where explosives can’t, with top-down cutting that lets you reach valuable mineral seams and get the most product out of the ground as possible.
The Cat® product line for surface mining is unmatched, with equipment for drilling and digging, loading and hauling, and maintaining efficient mine sites. Cat equipment is designed to lower cost per ton by providing productive and reliable performance. But what happens beyond the iron is what makes Cat surface equipment stand out.

The U.S. Government's Official Website for the Office of Surface Mining Reclamation and Enforcement (OSMRE) Western Region (WR). OSMRE's business practices are to reclaim abandoned mine lands (Title IV), regulate active coal mines (Title V), and apply sound science through technology transfer.
May 31, 2017· Colossal earth-moving machines became symbols in the 1960s-1970s environmental battles over surface coal mining, also known as “strip mining.” These machines some capable of scooping two-to-three Greyhound bus-size equivalents of earth with each bite laid waste to tens of thousands of acres as they uncovered near-surface coal to
A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.
Another highlight of Anglo American Platinum’s just released 2019 report was the revelation that electric narrow reef mechanised equipment is set for trials at its Tumela 15E underground platinum mine, part of the Amandelbult Complex in Limpopo province. These new narrow reef machines use lithium-ion batteries which can achieve up to 2,000 charging cycles.
Surface mining process somewhat varies depending on how the target mineral deposit is situated, e.g. horizontal, inclined, or interbedded, but commonly includes the following four steps: 1) top soil removal, 2) overburden removal, 3) extraction of ore, and 4)
Surface 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
Oct 17, 2020· Surface mining is a method of mining used to extract minerals and metals which are near the surface of the Earth. There are three basic types of surface mining: open pit mining, strip mining, and quarry mining.These methods are much more economical than underground mining, yet they can have a more significant impact on the surrounding environment unless efforts are taken to
