Abstract Mine production is along with water, fire, gas and coal dust, roof and other complex natural disasters and with the characteristics of poor, dangerous working conditions. Internet of Things (IOT) as an emerging technology provides a new technique for safety and security to underground production. According to the needs of mine safety production, key technologies of Internet of Things are introduced. That the technologies are RFID technology used to label things, sensor technology used to percept things, intelligent technology used to think about things, and intrinsic safety technology. Mine IOT key technologies and the research content are analyzed in-depth which have provided a direction for the research and application of mine IOT. Emphasis on IOT fundamental theories research, breakthrough in core technologies and strengthen research on key technologies that all these will effectively promote technology innovation in mine safety production.
