Abstract

A supply system for an underground mining machine, requiring both electricity and fluid (e.g. water), in which an insulated electric cable 10 is contained within the fluid conduit 6, affording protection for the electric cable. The cable may be supported in the conduit by a number of spacer members 12. <IMAGE>
