Abstract: Current status of mine Internet of things technology and its industrial development pattern were introduced. It was pointed out that top-down design of mine Internet of things was for designing perception mine from the state safe production supervision, realizing objects connection of mine Internet of things, and confirming service essence of mine Internet of things. Development trend of mine Internet of things was discussed, namely key technologies would be broken through continuously, service carrying pattern would appear gradually, and the government and enterprises would promote development of mine Internet of things jointly. Following development fields of mine Internet of things were focused on: breakthrough of core and key technologies including intelligent equipments with micromation and energy capturing technology, mine network, communication and post-disaster reconstruction technology, cloud computing, big data and safe production management technology, mine semanteme and virtualization technology, and safety, privacy and credible network technology; five sensing application including sensing miner, sensing disaster, sensing equipment, sensing mine area and sensing management; construction of cloud service hierarchy; standardization construction. Safeguard measures and construction route of mine Internet of things were proposed.
