A system for providing utilities and support infrastructure on a continuous basis from the surface to the cutting face of an underground operation. A flexible belt structure system incorporates water supply and discharge lines (102, 106), power and communication cables (112, 120), hydraulic supply and return lines (116), bulk lubrication delivery systems, and belt support structure for underground coal haulage. The system consists of modular components (26) that are added at the surface and connected underground to form a continuous support structure to the working area, such that the infrastructure necessary for th e mining operation is expanded or reduced to keep up with the position of the mining face without interruption of operation. The belt structure is mounted on a stationary rail (28) fixed to the roof of the mine and is rolled forward or backwards in the belt entry as the mine advanc es or retreats, as applicable.
