Abstract: In process of digital mine construction，information systems of mining production get large and complex，which produces such problems in mining information management as low supporting of real-time acquisition，separate and heterogeneous data formats，real-time sharing difficulties，complex mass storage and analysis difficulties.Therefore，in view of above problems，based on summarizing the status quo of the digital mine development，Nolan stage model of digital mining construction is analyzed，finding that our digital mining construction will face new challenges and more advanced demands in the information integration stage.With the help of systems engineering，database application technology，network technology，software architecture and cloud storage，a new concept of digital mining information integration mode is proposed，and the information integration model with characteristics of real-time storage，high sharing，reliable performance，and supporting intelligent data fusion among mining enterprises was established.According to the frame，integration of heterogeneous data is realized by adopting the Web Service and XML technology.
