Abstract: In order to realize the status monitoring，fault warning，preventive maintenance，remote maintenance，maintenance decision，optimized operation，overhaul guidance and other functions of the belt conveyor transport system and equipment，an expert system for intelligent operation and maintenance of belt conveyor equipment is built with the operation，maintenance，overhaul and equipment management of belt conveyor as the center. The system collects real-time data and fault records of the belt conveyor through underground ring network，and combines mechanical characteristics，equipment mechanism model and knowl⁃ edge base of the belt conveyor. Through data analysis and reasoning，the system provides maintenance plan and auxiliary decision for the operation and maintenance management of the belt conveyor，avoids major equipment failures，and effectively improves the operation efficiency and reliability of the belt conveyor.

Key words: intelligent operation and maintenance management, software design, auxiliary decisionmaking, data statistics and analysis, monitoring interface development
