HC Deb 15 November 1920 vol 134 c1535W

asked the President of the Board of Trade what was the average output per head per shift of the German mines in 1913 and 1920, respectively?


The output per man per shift in the Ruhr mines in 1913 was 883 kilogrammes and in Upper Silesia 1,144 kilogrammes or 17⅓ cwts. and 22½ cwts. respectively. I have no figures for 1920 for the Ruhr mines; for Upper Silesia the information available points to the output per man per shift in the first quarter of 1920 being about 620 kilogrammes or 12¼ cwts. I am endeavouring to get more precise information and shall be glad to supply the hon. Member with any further figures that I may be able to obtain.
