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.

Mountaintop removal is strip-mining on steroids. Massive dump trucks, huge bulldozers, and ten-story-high draglines can undo in months what geological processes took millions of years to build. Typically, multiple coal seams are exposed as a mountaintop-removal operation dismantles the .

What causes acid drainage? 1) The acid is already present in trapped underground pockets and is released by mining equipment. 2)Concentrated acids used to dissolve metals from the rock are picked up in rainwater. 3)Abandoned mining equipment leaks acids from batteries.

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.

Mar 12, 2017· Surface or strip mining damages and pollutes ecosystems to a great degree.

The major drawback of surface mining is the method destroys large areas of land, demolishing landscape and natural habitat to recover coal. Is deep drilling worth the cost? While underground mining requires an array of resources, equipment and financial backing, the method is best suited if the environment and coal potential harmonize.

Auger mining can be used for coal outcrops on a hillside or in strip mines where the stripping ratio has become too high to be economical for strip mining (Schobert, 1987). In auger mining, an auger drills it way into the face of the coal seam, and the coal is removed via conveyor and loaded directly onto a truck.
