The objective of this research was to design a method to continuously convey coal from a mining machine to a main haulage belt with the fewest operators. The multiple-unit, continuous- haulage (much) system was designed to provide the capacity to convey the coal. The much system has one operator who steers the lead vehicle, following the mining machine. All the remaining vehicles follow the path of the lead vehicle with their conveyors automatically lining up between the lead vehicle and mine section panel belt. This is accomplished by linkages on the vehicles that are interconnected by steering bars. An operator steers the discharge vehicle when outby travel is required. Surface tests indicate the system should track and retrack successfully in square- pillar underground room-and-pillar mines with 18-ft-wide entries and slopes up to 10 pct. For 60 deg. Pillar plans, the minimum entry width required is 15 ft. The tests also indicate the system will convey over 8 ton/min of coal around 90 deg corners without excessive spillage.
