Coal mining Wikipedia
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine a pit, and the

What Is Surface Mining? Convergence Training
These mining categories are: strip mining, open-pit mining, mountaintop removal, dredging and high wall mining. All methods of surface mining will remove the waste material, or overburden, above the desired resource. Surface mining is often preferred to sub-surface (underground mining) by mining companies for several reasons.

Strip Mining, Open-pit Mining, Surface Mining, Mining
Strip Mining. Strip mining is a kind of surface mining. The ore is very near to the surface of the land but has one or more layers of rock and filth on top of it. To mine the ore, these layers have to be removed. The steps in strip mining are similar to open-pit mining.

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.
