NTIS: PB/86-239795 :225 pages
The auto-track bridge conveyor train (abct) is a continuous haulage system designed for underground coal mines. The abct is made up of identical "units," each of which consists of a wheeled mobile bridge carrier and a bridge conveyor. Microprocessors located on each carrier enable the entire train to follow precisely a predetermined course along the section's haulage route with minimal operator control requirements. Sensors determine each carrier's position with respect to a signal cable. This cable is automatically deployed on the mine floor as the system advances behind the continuous miner. This report summarizes system design efforts, prototype testing, and subsequent redesign and prototype modifications.
