Surface mining methods: Strip Mining involves stripping the surface away from the mineral that's being excavated (usually coal). Soil, rock, and vegetation over the mineral seam is removed with huge machines, including bucket-wheel excavators.
Recently, new approaches using a method developed in the field of data science are actively applied for microstructure characterization. For example, the support vector machine (SVM) [8], a popular data mining algorithm for classification, is used to detect various defects of steel alloys [9], [10], [11].Further applications of SVM are given by Gola et al. [12], where steel …

Underground mining involves creating tunnels deep into the Earth that can access a deposit and extract it with ease. While this type of operation is time consuming and expensive due to the need for specialized equipment and skilled personnel, it often yields higher quality results than alternative mining methods due to its ability to access hidden deposits deep within a rock face …
In the longwall mining method, mine development is carried out in such a manner that large blocks of coal, usually 100 to 300 metres wide and 1,000 to 3,000 metres long, are available for complete extraction (see photograph).A block of coal is extracted in slices, the dimensions of which are fixed by the height of coal extracted, the width of the longwall face, …
