Abstract:Geological data management has great significance to the entire geological project management in geological exploration. Geological data management plays the role of connecting the past and the future and later geological data use during the whole project process. Through analyzing the significance and methods of geological data management, the safety of geological data management and the importance of big data integration in the whole process of a project have been discussed. Geological projects system construction can effectively promote specific management, enhance operability for geological data in practical use and make the most of existing geological data. It also makes better services to geological exploration,mining production, ecological environment construction and resource management.
