§ 49. Mr. Johnasked the Secretary of State for Trade and Industry if he will list the pits and the coal faces which do not meet the interim gravimetric standards at the latest convenient date.
§ Mr. EmeryI am pleased that the proportion of faces which fail to meet the interim gravimetric standard has been reduced from over 30 per cent, when the standard was first introduced on 1st April 1970 to 7.7 per cent, at 31st March 1973. The composition of the list changes from month to month due to varying geological conditions at individual mines, and I have asked the Chairman of the National Coal Board to write to the hon. Member with an up-to-date list and other relevant information.
