HC Deb 10 January 1977 vol 923 cc349-50W
Mr. Wigley

asked the Secretary of State for Energy what proportion of the United Kingdom's known reserves of recoverable coal lies in Wales.

Mr. Eadie

The proportion is 25 per cent., but the proportion that would be economically recoverable, under current market conditions and using present mining techniques, is lower at 8 per cent.
