HC Deb 26 June 1984 vol 62 c375W
Mr. Deakins

asked the Secretary of State for Energy what is the cost of producing coal at each pit in Britain; and how many pits are within one and two standard deviations, respectively, of the mean cost.

Mr. Giles Shaw

This is a matter for the NCB. I will ask the chairman to write to the hon. Member.
