[0002] A mine is an independent production and operation unit that extracts ore within a defined mining boundary. A mine mainly includes one or more mining workshops (also called pithead, mine shaft, open-pit mine, etc.) and some auxiliary workshops. Most mines also include ore dressing plants (coal washing plants). Mines include coal mines, metallic mines, non-metallic mines, building material mines, and chemical mines, etc. Mine size (also called production capacity) is usually expressed in annual output or daily output. Annual output is the quantity of ore produced by the mine each year. Based on output size, mines are classified into three types: large, medium, and small. The size of the mine should be commensurate with its economically reasonable service life; only in this way can infrastructure costs be saved and costs reduced.
