HC Deb 24 January 1967 vol 739 c235W
Mr. Concannon

asked the Minister of Power what would be the rate of increase in productivity in the coal industry by 1970 if 330,000 men at 320 pits produced 170 million tons of coal that year.

Mr. Freeson

If there were no significant change in the number of hours worked, output per man shift overall would be 48 cwts. in 1970, compared with 36 cwts. in 1966. This would be an increase of about 7½ per cent. per annum.
