HC Deb 04 June 1962 vol 661 c11W
Mr. Spriggs

asked the Minister of Power what he estimates the effect will be upon coal production of the proposals made by the Chairman of the National Coal Board to cut out uneconomic pits.

Mr. Wood

None, apart from a reduction in costs. Tonnage lost through closures can be replaced by tonnage from other pits, including new and reconstructed pits.
