Abstract：Aiming at the problems that poor sense of reality,ineffective monitor,and poor reliability of the traditional monitoring system in mechanized mining face,a method of 3D online monitoring was proposed based on WPF technology. This method used 3D visualization technology to establish the simulation model of fully mechanized mining equipment and environment. Some key issues of the model driving were elaborated,such as data acquisition and data communication in detail,the data server was added in the data communication system,which makes the communication system configuration and data push more convenient,and improves the data security of the monitoring system. The test results show that the 3D online monitoring system realized by this method has the advantages of simple operation,high reliability,high reliability and wide application prospect.
