Abstract: Prospect of mine internet of things was given, which was realizing connection among objects in mine, decreasing even eliminating monitoring blind area, and adopting could computing and big data technologies to get useful monitoring information, so as to realize intrinsically safe mine. Development trend of mine internet of things was sorted out from aspects of technologies and service mode. Corresponding concepts were expounded including fog computing technology, network fractal structure, ontology of mine things and intellectualization, cloud computing and big data technologies and so on as well as their application and development in mine internet of things, and cooperative working mode and buying services mode were expected.
