Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

The mine operating on a narrow margin must be prepared to survive periods of depressed metal prices. One tactic to deal with such a situation is to adjust the bound aries of the area being mined and draw these boundaries at a higher cutoff grade. This will increase the value of the runofmine product, and the mine will maintain its profit.
