HC Deb 31 May 1938 vol 336 cc1852-3W
Mr. Sexton

asked the Secretary for Mines whether he will state the number of mines in England and Wales with electricity installed underground for purposes of coal-cutting, haulage, etc.; the annual output of such mines; the number of persons engaged below ground; the number of explosions occurring in those mines, and the number of fatal and nonfatal accidents which have resulted from explosions during a period of the last available 10 years; and. similar statistics for coal mines where no electricity is installed below ground?

Captain Crookshank:

As this information is not fully available, and the collection and extraction of that which is available would involve a great amount of time and labour, I am communicating with the hon. Member in the matter.
