§ 5. Mr. TINKER
asked the Secretary for Mines how many coal conveyors were in use underground in the coal mines of Great Britain in December, 1930; how many tons they will carry over a given period; and will he give corresponding figures for 1924?
§ Mr. SHINWELL
During 1930 the number of conveyors in use at the coal face was 2,991 and elsewhere below ground 756. No information is available as to the total capacity of these conveyors, but the quantity of coal so conveyed in 1930 was 421 million tons. Similar figures for 1924 are not available, except that the number of face conveyors then in use was 1,373.
§ Mr. FREEMAN
Can my hon. Friend say if these conveyors are proving highly satisfactory and how many mines now use them entirely to the exclusion of pit ponies and horses?
