channel slide rail
One of a pair of rails used in a method of temporary rail-track advance at a tunnel face. The rails comprise a pair of specially made channels with ramp ends. They fit over the rail section in use and are pushed forward periodically as a power loader clears the rock ahead. The permanent track is extended as space becomes available.
