Application of “one network one station” wireless communication system in coal mine

For problems of disperse management and difficult maintenance of each informatization system in Shendong Coal Mine, as well as difficult recovering and inconvenient emergency rescue after accidents, a “one network one station” wireless communication system was proposed. The system integrates multi systems for unified accessing, carrying, management and linkage including 3G wireless communication system, personnel positioning system, video monitoring system, voice broadcast system, dispatching control system, etc. Application in Daliuta Coal Mine and Shangwan Coal Mine shows that the system realizes functions of integrated dispatching, remote monitoring, linkage of multiple dispatching terminals and video of coal mine.
