Coal type determines the composition of coal and it reflects the degree of oxidation during coalification. Based on the van Krevelen diagram (van Krevelen, 1993), coal consists of three key material groups including vitrinite, liptinite and inertinite, which are composed of distinct constituents called compares the key characteristics of coal macerals (van Krevelen, 1993).

Coal may be classified in rock types (or lithotypes) based on the presence of petrological components known as macerals. Based on maceral content and its appearance in a hand specimen, coal is classified into four principal types: clarain, durain, fusain, and vitrain. Coal may also be classified in grades using subjective terms (, "lowsulfur coal," "highash coal") with reference

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Conveyors or cars (railway wagons) transport the coal to vertical shafts for removal from the mine. After the coal is brought up to the surface by conveyors, it undergoes a process that removes sand and mud by immersing the coal in a solution of water and tiny magnetite particles. The different elements separate naturally. The coal floats while the other ores, called tails, sink to the bottom

· Coal and Transport . There are also close links between coal and transport, as the former needs a strong transport network able to move bulky goods. The roads in Britain before 1750 were very poor, and it was hard to move large, heavy goods. Ships were able to take coal from port to port, but this was still a limiting factor, and rivers were often of little use due to their natural flows
