Abstract: According to actual situation of Jining No.3 Coal Mine, a design scheme of integrated automation system platform of coal mine based on Wonderware IAS was proposed. Platform structure, IAS development, communication between the platform and interface protocol of other subsystem, HMI design method based on InTouch configuration software were introduced. The practical application showed that the platform is stable in operation, and improves coal mine informatization degree effectively, solves problems of self running and self management, which achieves goal of increasing efficiency by downsizing staff.
