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. Open-Pit Mining is a technique of extracting rock or minerals from the earth by their removal from an open-air pit.

The operation of the fine crushing plant is independent, to a large degree, of the performance of the primary crusher. A great deal of thought has been given to the problem of attaining maximum efficiency in this type of operation. Efficiency is measured by the work of reduction on the ore per unit of time and by percent running time.

Coal is a combustible rock mainly composed of carbon along with variable quantities of other elements, mostly hydrogen, sulphur, oxygen and nitrogen. Coal occurs as layers, called coal beds or coal seams, that are found between other sedimentary rocks. Coal is slightly denser than water but less dense than most of the rocks of the Earth's crust.
