Strip mining is a mineral-extraction process in which a layer or seam of undesired material (called "overburden") is removed from the surface of an area to allow efficient access to a desired material existing underneath the layer being stripped. As the process suggests, it is a form of surface mining, and it is primarily used to extract ...

In addition to being safe and efficient, precision surface mining methods are helping miners create better sustainability practices. The vibrations caused by blasting can damage nearby infrastructure, including roads, utility lines, pipelines and buildings. To avoid this, mines are forced to abandon areas within close proximity to these obstacles.
Strip mining can extract minerals like coal, iron ore, gold, copper, and uranium. Some of its examples are underground, open-pit, and underwater mining. Below are detailed explanations of some examples of strip …
Fig. 5. Box cut, strip cuts and spoil piles (Humphrey, 1984). mining access are either taken through the over burden dump as a valley, dozed through the spoil pile parallel to the strip, created in the highwall either parallel or at right angles to the strip, or by a combination of these alternat ives. Draglines are ofte n supplemented by throw

When considering all the mining operations in the world, at least 40 percent of mining takes place at the surface reports Greenpeace International. ...
The actual mining occurs at this step. It is done in a narrow strip in an elongated form. First, the primary strip is mined for coal. After it is extracted thoroughly, the second strip is created by removing filth, rock, and waste from the top. This debris is dumped on top of the first and used strip. The process repeated till the last strip is ...
