Abstract: Many problems exit in manual dispatching diagram,such as waste of time and manpower,low efficiency and lack of error correction methods.The system functions and a new failure-handling business process were determined by taking standardization,modularization,smartness,visualization as the targets.And then,technology solutions of database,graph drawing,fault index statistics and visualization were designed.Based on visual C# 2013 integrated development platform and SQL Server 2008 database,a computer-based equipment dispatching diagram and management system in open-pit mine was developed.The system showed strong expansibility and practicability,and it achieved visualization of the dispatching diagram.It also improved the capability and the accuracy of the real-time statistical information harvesting.Tests were conducted in Fushun west open-pit mine,with the satisfied result achieved.

Key words: Open-pit, Equipment management, Dispatching diagram, Availability ratio, Utilization ratio
