Abstract: In view of problems of bad image effect of video monitoring and control in process of automation production on fully-mechanized coal mining face, a monitoring and control system based on virtual reality technology was designed, and function design, structure composition and key technologies of the system were introduced. The system uses virtual reality technology to build up a high-fidelity virtual mine operation scene, and realizes functions of collection, transmission, display, warning and reverse control of real-time state information of production equipment on fully-mechanized coal mining face. The system meets needs of automatic production and monitoring on fully-mechanized coal mining face.
