5G communication technology and its application conception in coal mine

Abstract

In recent years, WiFi and 4G communication technology are preferred in coal mine wireless communication system in China. With development of intelligent construction of coal mine, the performance of coal mine wireless communication system cannot meet needs of intelligent development of coal mine. The paper described key technologies and performance advantages of the fifth generation mobile communication technology (5G) by comparing with previous generation mobile communication technologies. It also discussed composition and networking mode of mine-used 5G wireless communication system. Combined with characteristics of 5G communication technology and needs of coal mine intelligentization development, it put forward application scenarios of 5G communication technology in coal mine, such as underground unmanned driving and intelligent transportation, whole mine location service, equipment remote control, fault remote diagnosis, large broadband service data transmission, coal mine robot cloud control, whole mine safety monitoring information collection, virtual reality/augmented reality mine. It is pointed out that 5G technology application scenarios for coal industry still need to be continuously explored and improved, and since 5G network has high requirements for carrying network, coal mine should estimate deployment cost, and build mine 5G communication network based on its own development status and needs.
