§ 50. Mr. LEE
asked the Secretary for Mines if he can give the percentage of collieries in the various districts of the British coalfields where coal-cutting and conveying machinery is in use at the coal face, giving the output per man per shift in comparison with the output previous to the introduction of such machinery?
§ The SECRETARY for MINES (Commodore Douglas King)
As the reply involves a number of figures, I will, with
|District.||Number of Collieries at work in 1927.||Percentage of Collieries using Coal Cutting Machines and/or Conveyors at the coal face.|
|3.||Cumberland and Westmorland||35||29|
|4.||Lancashire and Cheshire||234||41|
|12.||South Staffs and Worcester||116||2|
|16.||Forest of Dean||57||7|
|20.||South Wales and Monmouth||638||24|
|22.||Fife and Clackmannan||68||76|
|23.||Lothians (Mid and East)||31||68|
|24.||Lanarkshire, Linlithgow, Stirling, Renfrew and Dumbarton.||284||58|
|25.||Ayrshire, Dumfries and Argyll||79||42|
§ I regret that as the machinery has been introduced very gradually over a long period, it is not possible to fix a basic date which would enable me to answer the last part of the question.
