Abstract. Most coal requires some preparation before use. Preparation may range from simply crushing to provide a size consist suitable for certain types of boilers to extensive size reduction and cleaning to remove sulfur and ash-forming mineral matter.

A coal preparation plant typically operates with multiple cleaning circuits to clean individual size fractions of run-of-mine coal.

Surface mining techniques are categorized as either strip, open pit, or mountaintop removal. Strip mining is a method used on flat terrain and involves removing soil or rock above a layer of coal, exposing the coal seam for mining. One type of strip mining is contour mining, where extraction activities occur on a hillside.
