HC Deb 01 May 1947 vol 436 c2146
5. Mr. W. Shepherd

asked the Minister of Fuel and Power the percentage of total output which is consumed by coalmines; and what steps are being taken to reduce this consumption.

Mr. Shinwell

Six per cent. of the output of coal mines is consumed by the collieries. The National Coal Board inform me that it is their intention to intensify and extend the work done hitherto to improve the efficiency of utilisation of coal at collieries.
