The benefits of continuous face haulage in underground continuous miner sections have long been recognized. These benefits include increased section production of coal and safety enhancements, and have been documented in some specific mine operations. Both private industry and the government continue to make technology improvements that will promote the greater use of continuous haulage in underground coal mines. Although the initial capital costs for continuous face haulage in some instances may be higher than batch-type transport, increases in shift production and productivity with continuous haulage shuld offset these costs. The goal is to increase shift production of coal and reduce operating and accident-related costs enough to justify the initial purchase and long term use of this technology. In some mining conditions, continuous face haulage may not be just an alternative to batch-type transport, but the only means by which some coal seams can be extracted. The overall goal of DOE is to increase average room-and-pillar miner production by up to 45% via continuous facehaulage. If reduced place-changing (RPC) mine plans can be employed via miner-bolter type schemes that mine break-to-break, a further section production improvement up to 27% is conceivable. Thus, the maximum combined impact of reliable continuous face haulage being used in RPC mine plans is to increase room-and-pillar miner production in thinner coal seams by almost 85% as compared to continuous miner/shuttle car units extracting about 20-feet (6.1 m) and then changing place. This ambitious goal can be achieved in the years ahead if progress continues to be made in these technological areas.
