Classification of Coal Engineering ToolBox

Coal is a readily combustible rock containing more than 50 percent by weight of carbonaceous material formed from compaction and indurations of variously altered plant remains similar to those in peat.. After a considerable amount of time, heat, and burial pressure, it is metamorphosed from peat to lignite.

coal classification Types & Facts Britannica

Coal classification, any of various ways in which coal is grouped. Most classifications are based on the results of chemical analyses and physical tests, but some are more empirical in nature. Coal classifications are important because they provide valuable information to commercial users (e.g., for power generation and coke manufacturing) and to researchers studying the origin of coal.

What are the different types of coal? American

The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or “ranks,” of coal are determined by carbon content.

Obtaining coal from the mines is a difficult job. First, the dirt above the coal deposit is removed. When the coal is exposed, explosives are used to break it into smaller pieces. The coal thus collected is loaded into wagons and lifted to the surface. The mines enter and leave the mine by an elevator through a vertical space called the shaft.
