§ 57. Mr. BROMLEYasked the Secretary for Mines how many coal mines and which, if any, in Great Britain have mechanical haulage installed underground, and consequently use no pit ponies for that purpose?
§ Colonel LANE FOXThere are approximately 1,300 mines where horses are not used below-ground. These include many small mines where the absence 823 of horses does not necessarily imply the presence of mechanical haulage. Nearly all mines employing horses make use of mechanical haulage as well. The number of mines at which no horses are used but which have an electrical haulage system underground is 324.
