Reasons for the British coal mining is called a “sick” industry today.
Today the coal industry in Britain is on the decline，the number of miners， collieries and the total output have been falling.
The reasons for the decline are as follows： exhaustion of old mines， costly operations of extraction， poor old equipment， little investment， fall in demand due to imports of cleaner， cheaper and more efficient fuels， etc.
Britain‘s oil and natural gas
Natural gas was discovered in 1965 and oil in 1970 under the North Sea. Today Britain is not only self-sufficient in oil but also has a surplus for export. The transport and domestic heating systems mostly depend on oil. So does the food supply， because most agriculture is highly mechanized. Modern farming requires things which are all oil-based.
Main problems associated with Britain‘s iron and steel industry today.
British iron and steel industry is declining for the following reasons：
1. Local supplies of iron ore have become exhausted；
2. Old fashioned furnaces for making coke cannot recover valuable by-products；
3. Blast furnaces， steelworks， and rolling mills are often separated from each other and thus cannot perform as well as more compact operation；
4. Many steelworks have to be closed down， causing major unemployment in an area.
