Coking coal of the United States—Modern and historical ...

Coking coal, or metallurgical coal, has been produced in the United States for nearly 200 years. Coking coal is primarily used in the production of coke for use in the steel industry, and for other uses (for example, foundries, blacksmithing, heating buildings, and brewing). Currently, U.S. coking coal is produced in Alabama, Arkansas, Pennsylvania, Virginia, and West Virginia.

What is the process of coal mining? - R4 DN

What is the process of coal mining? The surface rock (called overburden) covering the coal is then blasted with explosives and removed by excavators. Some coal is mined by the Bord and Pillar method. This is where a machine continually cuts into the coal. It tunnels through the coal seams leaving pillars supported by roof bolts to hold up the roof.

Carbonization of Coal - EOLSS

2.1 The Coking Process of Coal in the Oven Chamber When coal is charged into a hot coke oven, that portion of the coal directly in contact with the walls is heated very rapidly. When its fusing is reached, the thin layer of heated coal softens and fuses. Destructive-distillation reactions proceed rapidly in the plastic

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".
