what is the coal mining process
Metallurgical coal
Metallurgical (met) coal (or coking coal) is a naturally occurring sedimentary rock found within the earth's crust. Categories of met coal include hard coking coal, semihard cokingcoal, semisoft coking coal and pulverised coal for injection (PCI). These apply to the different quality grades of met coal, all of which are used to make steel.
