Where is coal found? | World Coal Association

Reserves that are not only considered to be recoverable but can also be recovered economically. This means they take into account what current mining technology can achieve and the economics of recovery. Proved reserves will therefore change according to the price of coal; if the price of coal is low, proved reserves will decrease.

Coal - Wikipedia

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

Alaska Coal Resource: Potential for future development

For coal to count as part of recoverable reserves, it must first be well-studied, with densely spaced boreholes or documented outcrops. Also, it must be economically feasible to extract it with current technology. Recoverable reserves are reported by various governments to the World Energy Council (WEC) and then are compiled into various reports.
