Abstract: According to the information features of Jiahe Mine and the demo project design requirements of the sensory mine internet of things, a study and plan de sign were conducted on the sensory mine internet of things in Jiahe Mine .Based on the 1 000 MB Industrial Ethernet link network as the backbone and the wireless net work with SmartMesh functions as the supplement, the wireless network was covered the full mine Based on the three sensory conceptions of the internet of things, a m obile target continuous positioning in underground mine was realized based on GIS.The positioning accuracy would not be over 5 m and the sensory and pre-warning C ould be conducted on the around environment parameters.The working status and health information of the equipment could be integrated and the health status sensor y of the equipment could be realized .Finally the paper pointed out that the disaster pre-warning to be solved should be applied with the distribution type disaster sensor y mode based on the internet of things.
