Abstract

Control circuit failures contribute significantly to continuous miner downtime. The time required to put the machine back into production is a function of the time required to diagnose the problem, obtain parts and make the repair. Of these, the diagnostic time is often the largest. A microprocessor-based system with the ability to diagnose all of the common control circuit failures was designed, installed on a continuous miner and tested. This paper summarizes the development of the diagnostic system and provides examples of the system's diagnostic capabilities. Implementation issues and the hardware used for the prototype are briefly described. Comments on the system's performance are also presented. -Authors
