Abstract: In view of the aging of the existing communication system in Longhua Coal Mine, the limited development of technology, the weak wireless signal and the small amount of information transmission, based on the analysis of the existing mine communication technology, a set of 4G+5G+Wi-Fi6 communication system which can integrate the existing communication system is established. The system adopts the mine-specific 5G core networking architecture, and the data is communicated internally, which ensures the high security and low latency of data transmission. The system integrates the existing communication system of the mine, realizes the business functions of voice call, video call and mobile business functions, as well as the non-business functions of recording, conference and integrated communication, and meets the information transmission function requirements of large data transmission in each working area of the mine.
