Coal and Its Classification
Coal is the product of vegetable matter that has been formed by the action of decay, weathering, the effects of pressure, temperature and time millions of years ago.
Although coal is not a true mineral, its formation processes are similar to those of sedimentary rocks.
Structurally coal beds are geological strata characterized by the same irregularities in thickness, uniformity and continuity as other strata of sedimentary origin. Coal beds may consist of essentially uniform continuous strata or like other sedimentary deposits may be made up of different bands or benches of varying thickness.

152 Unit 6
Thus, in Fig. 3 one can see a seam limited by two more or less parallel planes, a shape which is typical of sedimentary rocks.
The benches may be separated by thin layers of clay, shale, pyrite or other mineral matter, commonly called partings (Fig. 4).
Like other sedimentary rocks coal beds may be structurally disturbed by folding and faulting.
According to the amount of carbon coals are classified into: brown coals, bituminous coals and anthracite. Brown coals are in their turn subdivided into lignite and common brown coal.
Although carbon is the most important element in coal, as many as 72 elements have been found in some coal deposits, including lithium, chromium, cobalt, copper, nickel, tungsten and others.
Lignite is intermediate in properties between peat and bitumi nous coal, containing when dry about 60 to 75 per cent of carbon and a variable proportion of ash. Lignite is a low-rank brown-to-black coal containing 30 to 40 per cent of moisture. Developing heat it gives from 2,500 to 4,500 calories. It is easily inflammable but burns with a smoky flame. Lignite is liable to spontaneous combustion. It has been estimated that about 50 per cent of the world's total coal reserves are lignitic.
Brown coal is harder than lignite, containing from 60 to 65 per cent of carbon and developing greater heat than lignite (4,000-7,000 calories). It is very combustible and gives a brown powder. Bituminous coal is the most abundant variety, varying from medium to high rank. It is a soft, black, usually banded coal. It gives a black powder and contains 75 to 90 per cent of carbon. It weathers only slightly and may be kept in open piles with little danger of spontaneous combustion if properly stored. Medium-to-low volatile bituminous coals may be of coking quality. Coal is used intensively in blast furnaces for smelting iron ore. There are non-coking varieties of coal.
As for the thickness, the beds of this kind of coal are not very thick (1-1.5 metres). The great quantities of bituminous coal are found in the Russian Federation.
Anthracite or "hard" coal has a brilliant -lustre containing more than 90 per cent of carbon and low percentage-fit volatile matter. It is used primarily as a domestic fuel, although it can sometimes be blended with bituminous grades of coal to produce a mixture with improved coking qualities. The largest beds of anthracite are found in Russia, the USA and Great Britain.
Unit 6153
Coal is still of great importance for the development of modern industry. It may be used for domestic and industrial purposes. Being the main source of coke, coal is widely used in the iron and steel industry. Lignite, for example either in the raw state or in briquetted form, is a source of industrial carbon and industrial gases.
There is a strong tendency now for increased research into new technologies to utilize coal. No doubt, coal will be used as a raw material for the chemical industry and petrochemical processes. All these processes involve coal conversion which include gasification designed to produce synthetic gas from coal as the basis for hydrogen manufacture, liquefaction (разжижение) for making liquid fuel from coal and other processes.

ТЕКСТ В
l.For along time coal has been the principal fuel, the main source of thermal and electric energy. Now it continues to play an important part in the economy.
Coal is the product of vegetable matter that has been formed
from the remains of plants and animals accumulated in swamp areas
millions of years ago. Although some coals were deposited
4,000,000,000 years ago during the Silurian period, most coals were
formed during the Upper and Lower Carboniferous geological
epochs about 250,000,000 years ago.
Coal formation processes are similar to those of sedimentary
rocks. Various coal seams can be studied and related geologically to
the sedimentary rocks with which they are associated. Coal contains
varying amounts of carbon and volatile material as well as impurities
such as sulphur, phosphorus, incombustible rock material and
moisture.
The physical characteristics of coal concern the structural
aspects of the coal bed and texture. Structurally coal beds are charac
terized by the same irregularities in thickness, uniformity and
continuity as other strata of sedimentary origin. Thickness varies
greatly. Coal beds may consist of essentially uniform continuous
158 Unit 6
strata or like other sedimentary deposits may be made up of bands or benches of varying thickness. The benches may be separated by thin layers of clay, shale, pyrite or other mineral matter, commonly called partings. Like other sedimentary rocks coal beds may be structurally disturbed by folding and faulting.
Many classifications of coal have been suggested: by geologic
age, coking properties, commercial application and chemical
composition.
There exist four main types of coal: anthracite, bituminous,
subbituminous, lignite and brown coal. When speaking about the
classification of coal based on its nature as rock mineral, scientists
distinguish (различать) the following rock varieties or lithotypes
such as vitrain, clarain, durain and fiisain. These are the four
constituents (составная часть) of coal.
Although the utilization of coal varies widely with rank, three
general fields of coal utilization may be distinguished. They are
combustion (domestic, industrial, railroads and public utilization),
gasification and carbonification (high-temperature coke for
metallurgical uses and low-temperature coke for producing smokeless
fuel).

Energy in the UK: Changing Demands
Coal was the dominant form of energy used in the UK for over a century. Coal was plentiful and cheap. It has a variety of uses:
fuel for steam engines,
fuel for homes, factories and offices,
the production of gas,
the production of chemicals.
British homes were designed to cope with coal. Near the back door would be the coal bunker. There were open hearths on which coal and wood fires were burnt.
Open coal fires look very attractive, but they have many problems. Coal is dirty, heavy and difficult to use. Rooms can fill with smoke when a door is opened. When the fire is finished, soot and ash are left.
Alternative forms of energy have become widely available in the UK since the 1960s. Oil, gas and electricity provide most of the country's energy. It is not all bad news for coal, however, because it is still the most important fuel used to generate electricity. New cleaner methods of using coal to heat houses have been developed.
Oil, gas and electricity are much cleaner and easier to use than coal. The price of the different forms of energy is also an important factor:
During the 1960s oil and gas became cheaper while the price
of coal rose. Demand for coal fell dramatically.
In 1973/74 the Oil Crisis made oil much more expensive. Gas
and coal were cheaper. Gas took a larger share of the energy market
as the North Sea gasfields were developed. There was even a revival
in the use of coal. This was reinforced by the great oil price
increases of 1979/80.
160
Unit 6
' In 1986 oil became much cheaper. Demand for coal fell • again.
Price and ease of use have been the major factors affecting the changing energy demand in the UK in the last forty years. In the future the exhaustion of energy sources will become important. The world's oil supplies may not last more than another forty years. Much of the world's oil and gas is located in areas which have suffered conflict, such as the Middle East. Supplies may be cut off from the UK for political reasons, as they were, briefly, during 1956 and 1973. Home energy source, of which coal is the largest, will then become more important for the UK again.
Past experience shows that there are no certainties in demand for energy within the UK. The future may hold many changes.
