Abstract: Aiming at the problems of data islands,closed systems,and difficulties in information fusion in the construction of integrated mine management and control platforms,a datadriven mining big data fusion technology oriented to "Ore Stream" was proposed.According to the requirements of "ore stream" data source,data integration and data analysis,research on key technologies of mining big data system such as data collection,storage and standardized management technology,multisource data integration technology,and "ore stream" wholeprocess correlation technology were carried out.Taking the development of big data control platform of Sanshandao Gold Mine as an example,the whole process of mine “ore stream” was analyzed in detail,combined with the existing business processes of the mine,the Huawei big data platform was adopted to associate the data of resource reserves,mining,ore drawing,transportation and lifting,surface transportation and beneficiation and other technological links,an industrial platform of mine big data integrated control system based on "ore stream" was established,the unified optimization command and dispatch and the whole process control and control analysis of the whole process were realized on the unified platform,the timeliness,effectiveness,optimal allocation of resources and comprehensive strength of mine production and management were improved,and the coordinated operation and standardized management of mine were promoted,which could provide reference for the construction of intelligent mine.
