Abstract: In view of the problems of the collapse and unnormal use of integrated automation system of coal mine caused by network information transmission congestion and fault of network cable in the current network construction of Yanjing mining network, a new idea and feasible scheme of mine network construction based on mine automation is presented. According to the situation of Yanjing Mine, a multiple redundant network mode is established to prevent network failure caused by the total segment of the cable, and the safety law such as VLAN is designed, which ensures the normal transmission of network information. The site simulation test and long-term operation show that the network of Yanjing Coal Mine has the characteristics of high safety and high reliability.
