HC Deb 01 February 1937 vol 319 c1298W
Mr. Batey

asked the Secretary for Mines whether he can state the number of coal mines in operation in Great Britain; the number of separate undertakings; and the amount of capital invested on the latest available date?

Captain Crookshank

There are 1,893 pits at work and about 970 separate undertakings. I regret that I have no information which would enable me to make an estimate of the amount of capital invested.
