Abstract: In order to further accelerate the recognition and application of F5G technology in coal mines and promote the intelligent development of coal mines in China, based on the new F5G new technology, aiming at the advantages of large bandwidth, high reliability, flattening, easy deployment, easy management and other advantages of the PON network of the F5G all-optical industrial network architecture for mining, an intelligent coal mine construction scheme based on the Internet of Things, cloud computing, big data, artificial intelligence, automatic control, mobile Internet, and robots was constructed. This paper discussed the functions of F5G industrial optical network for mining, F5G+5G integrated networking equipment and architecture, and analyzed the application advantages of F5G+5G single network for mining underground; This paper focused on the advantages of the passive optical network of F5G intelligent construction scheme to meet the explosion-proof requirements of underground coal mine, the regular movement requirements of underground coal mine, and the business security of application scenarios; Four typical application scenarios of intelligent coal mine construction based on F5G architecture were studied: video monitoring+edge analysis, low delay real-time transmission of remote control network, monitoring transmission network, bearing network of mining 5G+ integrated communication system, which provides technical ideas and methods for intelligent coal mine construction based on F5G architecture. The characteristics, network architecture, application scenarios, advantages and ecology of the mine F5G network construction discussed in this paper are to promote the application of mining F5G+ intelligent coal mine scheme in underground coal mine and effectively 〖JP2〗promote the high-quality development of coal industry; At the same time, the in-depth promotion and application of coal mine F5G also needs the cooperation of the whole industry, including coal mine production enterprises, integrators, network equipment suppliers, etc., to build an innovative, collaborative, open and cooperative coal mine F5G application ecology.
