Abstract: Aiming at continuous water gushing accident of metal mines in our country，and applying with the technology of internet of things，the system with combination of automatic monitoring and intelligent recognition about water inrush with software and hardware is build，which can automatically monitor the height of underground gushing-water，and intelligently recognize the composition of gushing-water and its surrounding.All of these can reduce gushing-water accident.The production practice proved that this system is simple and feasible with a stable operation.Its good monitoring，alarming and intelligent recognizing functions make it own a brilliant foreground of application.

Key words: Internet of things, Water inrush, Monitoring, Intelligent recognition
