HC Deb 04 May 1971 vol 816 c326W
Mr. Sillars

asked the Secretary of State for Trade and Industry how many National Coal Board collieries are presently in operation; how many of these are high-cost pits as defined in the introductory note to Report No. 153 (Supplement No. 1) of the National Board for Prices and Incomes; and what is the labour force employed in them.

Mr. Ridley

At present there are 292 producing collieries operated by the National Coal Board. I am asking the Chairman of the National Coal Board to write to the hon. Member on the remainder of the question.
