Abstract
A mining machine is controlled by a fiber optic controlled remote control system that includes one or more fiber optic cables that extend from a remote control station through a hose supplying water to the mining machine. The fiber optic cables exit the water hose for connection to electrically operated equipment onboard the mining machine. Connectors having sealing glands with apertures therethrough allow for insertion of the cables into the water hose and exiting of the cables from the hose at the mining machine while preventing the escape of water from the hose at the points of insertion and exiting. The fiber optic cable is supported and positioned for movement in the hose to relieve tension on the cable when the hose is stretched.
