Key Technologies of Comprehensive Monitoring of Safety Production in Networked Coal Mine

Digital mining and unmanned mining have become the development trend of the coal industry at present. Aiming at the deficiency of the existing safety monitoring technology in coal mine in the aspects of progressiveness, reliability and real-time, this paper puts forward the key technology of networked coal mine safety production monitoring. The structure of the communication mode based on “one network one station” is discussed in this study, and the design method of the specific network is analyzed. The accurate locating method of mine moving target based on TOF is studied. The technology of mine fire monitoring system based on wireless self-networking is studied. This paper is of theoretical and practical value to improve the development of coal mine safety monitoring technology and the level of mine safety control.
