This report describes the installation and operation of a computer- based belt-monitoring and control system at the Barnes & Tucker Coal Company Mine No. 20 In Ebensburg, Pennsylvania. The system installed was the National Coal Board's mine operating system (minos) coal transport monitoring and control system. The program objective was to document (1) the installation requirements for a conveyor control system, (2) the operating experience with the system, and (3) the impact of monitoring and control on mine operation. Analysis of the system operation indicates that monitoring and control did improve belt availability significantly and reduced downtime associated with belt delays. Economic analysis showed the increased belt availability would potentially result in significant production increase and excellent payback of the initial investment. The system performed satisfactorily, was well accepted by the work force, and did not increase the maintenance workload.
