ANSWER-

USA:

The United States of America is the second largest producer of coal in the world. It produces about 17 per cent coal of the world. The coal regions of USA are distributed in whole of the country as shown in Figure 9.3.

Coalfields of the USA

The main coal-producing areas of USA are as follows:

The Appalachian Coalfields:

The Appalachian Coalfields, reaching almost without a break from northern Pennsylvania into northern Alabama, contain the finest bituminous coal lands of the world. On this basis this coalfield is also known as Eastern Interior bituminous coalfield. This coalfield falls into three groups:

The Northern Appalachian Coalfield:

Pittsburgh is the most important mining centre in north Appalachian Coalfield. The Pittsburgh Coalfield has an area of about 1200 sq km with many workable seams which are 2 to 4 metres thick.

The Central Appalachian Coalfield:

The Central part of this Appalachian Coalfield in West Virginia, eastern Kentucky, Tennessee, and part of Virginia was not developed so early because it was more difficult to access, but many mines were opened there after 1915. The Central Appalachian Coalfields have several fairly thick seams.

The Southern Appalachian Coalfield:

The Southern most of these Appala­chian Coalfields is in Alabama near Birmingham. This coalfield and the nearby deposits of iron ore and limestone are the basis of Birmingham’s steel industry. This Coalfield is very accessible to adjacent markets and hence has greater devel­opment than any other field South of Kentuky.

Eastern Interior Coalfields:

The Eastern Interior Coalfield is situated in Southern Illinois, Southern Indiana and Western Kentuky of USA and is famous for bituminous coal. The bituminous coal is not of as good quality as that of the Appalachian fields, but it is useful for steam and domestic purposes.

Northern Interior Coalfields:

Michigan State is now the centre of coal mining in the interior province, but Chicago remains the organizing centre of the iron and steel industry, not only of the Lake Superior region but in North America as a whole. Gary is another iron and steel town in Michigan coalfields.

Western Interior Coalfields:

This field, like its counterpart, the Eastern Interior field across the Mississippi, has important coal deposits of bituminous and subbituminus. The coal in Western Interior field is below average in quality. The Principal Coalfields being worked in Western Interior are Arkansas, Oklahoma, Kansas, Missouri, Eastern Nebraska and south western Iowa.

Southern Interior Coalfields:

The Southern Interior Coalfield is of little importance even locally because of the poor quality. Southern Interior is the extension of western fields in Texas. In the western interior and south western fields extending from Central Iowa to Central Texas are beds of bituminous coal that crop out along the eastern margin, where small quantities are mined for local consumption.

It is traversed by the Mississippi and its tributaries, in the bed of which the coal crops out in numerous places.
