Wirtgen supplies surface miners in a variety of performance classes for the selective mining of commodities, such as coal, limestone, bauxite, gypsum, salt and phosphate (Fig. 2). In addition to mining, these machines can also carry out routing operations for constructing roads and railway tracks, rehabilitating roadways and installing tunnel floors.
In most surface coal mines with near horizontally burial strata, inpit dumping will cover the end-wall slope of the previous mining district, causing increased secondary stripping amount when the ...
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.

For example, in coal and other soft rock mines, continuous miners break and load the mineral to eliminate drilling and blasting; boring machines perform the same tasks in medium-hard rock. The cycle of operations in surface and underground mining differs primarily by the scale of the equipment.

Coal Operations We deploy surface miners for the difficult applications – partings and thin seams. Partings that are deemed inseparable result in discarded or lower-quality coal. Our 35-year association has evolved into a true partnership based on trust, shared
Mining - Mining - Surface mining: It has been estimated that more than two-thirds 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 open-pit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced. Open-pit ...
