Abstract

A mineral winning installation employs a longwall scraper chain conveyor 17 at the mineral face a winning machine 19, such as a shearer or plough, and an independent constructional assembly arranged at the roof or floor for supplying facilities to the machine. These include a multi- sectioned rail or plate 21 carrying a toothed rack 23 in which a drive pinion 33 meshes. In addition, the rail or plate supports a sealed guard housing 24 containing an electric live track 26 and a further sealed housing 31 containing pressurized water. The machine has a pickup arm 29 which engages with a contact sliding along the electric track to supply electric power to the drive means and a conduit 32 which has a water collector displaceable along the water housing to supply water to the machine for dust suppression. <IMAGE>
