The monorail bridge conveyor (mbc) is a prototype continuous face haulage system that was surface tested and evaluated by the Bureau of Mines. The mbc consists of a series of cascading belt bridge conveyors suspended from roof-supported monorail track. Tests were conduted to determine mbc haulage capability, maneuverability, power consumption, and reliability using rigid and chain-suspended monorail track installations. Subsequent modifications to improve operation and reliability made during surface testing are described. Mining plans were devised to show potential mbc installations for room-and-pillar, longwall development, and shortwall mining sections. Compatibility tests were conducted with the Bureau's prototype hopper-feeder to provide additional surge capacity and lump-breaking capability. Results from the surface test program, along with modifications to improve system operation and reliability, indicate that the mbc has the potential to perform successfully in an in-mine trial.
