Abstract
A composite high pressure hose device for a mining machine has a flexible inner conduit 1 protected within a flexible outer sheath 10. An annular gap 12 is established between the sheath 10 and the conduit 11. Sensing means 14 built onto the device senses a change in the pressure in the gap 12 indicating leakage in the outer sheath 10 or the inner conduit 11 and can initiate a control sequence to shut-off a pump supplying the fluid or to actuate an isolating valve. <IMAGE>
