Abstract:

Abstract: The technology such as condition monitoring, automatic control and fault diagnosis used in armored face conveyors on longwall coal mine was studied. A monitoring and fault diagnosis system has been developed. The structure and function of the system were briefly described. Based on the pressure and path of the tensioner cylinder mounted on the tail-end of the armored face conveyor, the system achieved the pretensioning, manual control and automatic control function. Combined neural network with data fusion, the paper expounded fault diagnosis procedure. The result of field operation indicates that the system has stable operation. The system can satisfy the demands to monitor and diagnose running state of armored face conveyors and to control tensioning force of chains.
