Jul 15, 2019· The grade of coal and its caking ability are determined by the coal''s rank—a measure of volatile matter and degree of metamorphism—as well as mineral impurities and the ability of the coal to melt, swell and resolidify when heated. The three main categories of metallurgical coal are:
What are Minerals? All rocks except obsidian and coal are made of minerals. (Obsidian is a volcanic rock made of glass and coal is made of organic carbon.) Most rocks contain several minerals in a mixture characteristic of the particular rock type. When identifying a rock you must first identify the individual minerals that make up that rock.
The Division of Geology and Mineral Resources (DGMR) has mapped five major coalbearing geologic formations within this sequence of rocks including from youngest to oldest the Harlan, Wise, Norton, Lee, and Pocontas Formations (Nolde, 1994). The coal beds vary in thickness from less than 1 foot to about 11 feet (Brown and others, 1952).
