Coal explained Mining and transportation of coal

Mining coal. Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth''s surface, but others are deep underground.Modern mining methods allow U.S. coal miners to easily reach most of the nation''s coal reserves and to produce about three times more coal in one hour than in 1978.

The coal thus has to be first converted into coke. Coke is a more refined form of coal. Coal is heated to temperatures up to 1250°C in the coke ovens, in the absence of oxygen. This process is referred to as "dry distillation." It takes about 18 hours to convert 35 tonnes of coal into 25 tonnes of coke. The process involves burning coal to

How to Produce Green Coke? | Energy Proceedings

The main share is directly related to the use of fossil coke and coal as fuels and reducing agents. About four solutions can be adopted to address such issue: direct reduction with hydrogen or syngas, electric arc furnaces, carbon capture and storage and use of biofuels (so-called "biocarbon"). These solutions can also be integrated.
