Abstract

The system involves securing lengths of fixed conduit 14 to parts 8, 10 of the conveyor assembly, prior to the assembly of said parts at the underground mine working. When the conveyor assembly has been assembled, the length of fixed conduits are inter-connected, either by straight length of flexible conduit 16, or by branched lengths of flexible conduit, where take off for fluid under pressure is required for the machinery, for example a roof support unit. <IMAGE>
