Intelligent comprehensive mining working face is the trend of future development in mining. According to the basic situation of Dongjiang Mine comprehensive mining working face, the overall scheme of intelligent management system was designed and studied. The network framework of the scheme was divided into three levels, and key technologies such as high-definition video monitoring, remote control of coal mining machine and hydraulic support, and equipment linkage shutdown were introduced. The designed intelligent management system of working face was applied to the practice of mining engineering, and the test showed that the operation process was stable and reliable, which significantly improved the intelligence level of the mine.
