outside the mining area for placement and storage. In the Midwest, where the surface topography and coal seams are generally flat, it is common to employ area strip mining in which the fragmented overburden is placed directly by large draglines in the space created where coal has been mined ().In some situations in the eastern United States, a coal seam occurring near the top of mountains is ...

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, ia, and West ia.
The Hardgrove grindability index HGI is closely related to the power consumed in crushing coal and may be used to optimize crushing in the coal-preparation shops at coke plants, as shown in [1–7].The factors affecting HGI for Ukrainian and imported coal were studied in [].The results showed that HGI depends on the carbon content and structural order of the coal's organic …
