Coal Production
Coal production continues to grow globally due to the demand for low cost energy and iron and steel, as well as cement. Coal, based on the current extraction rates, will last about 115 years longer than conventional oil and gas reserves, with an estimated 1.1 trillion tonnes of proven coal reserves worldwide. Ten countries are responsible for 90% of the total …
Estimating carbon dioxide emissions from coal mines
For coking coal, the Production Gap report estimated 0.645 (64.5%) of the carbon dioxide should be "excluded", meaning these emissions will be counted in the process fuel or industrial category (e.g. metallurgic coke used in iron and steel production) rather than as power sector emissions.

Coking Coal: Explained
Coking Coal. Coking coal (or metallurgical coal) is a bituminous coal with a suitable quality that allows the production of metallurgical coke, or simply named coke. Coking coal has a higher carbon content than steam coal, as well as a lower level of sulphur, phosphorous and alkalis (World Coal Institute 2009).
Coal
The widespread use of kerosene reduced the use of coal oil in the 20th century. Coking coal is used in large-scale industrial processes. The coal is coked, a process of heating the rock in the absense of oxygen. This reduces the moisture content and makes it a more stable product. The steel industry relies on coking coal.

Coking Coal – IspatGuru
The term 'coking coal' is used to designate certain types of bituminous coals which, when heated at high temperatures (over 1,000 deg C) in the absence of air (carbonization), soften, liquefy, and then re-solidify into a hard but porous mass known as coke, used mainly in the production of hot metal in a blast furnace.

What are the types of coal? | U.S. Geological Survey
There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard …
