Abstract: Underground coal mining is a complex giant system,and the important foundation of its intelligent mining is the high sharing and dynamic analysis of the whole business process information of safety production. However,there are some problems such as weak basic theory of spatial information management,serious data island,backward man- agement mode,lack of shared platform and so on. Based on the characteristics of intelligent information processing in coal mine,the system design of intelligent coal mine information sharing management platform based on “one map” is proposed,which lays the foundation for horizontal and vertical integration between production and management depart- ments. further the gray geographic information system theory is improved for managing coal mine spatial information,the reconstruction of business process and the construction of spatiotemporal database are described in detail,which re- alizes the dynamic modification of coal seam spatial information,the innovation of management mode and the integrated storage of all kinds of spatial and attribute data under the intelligent mining environment,which guarantees the dynam- ic,sharing,accuracy and reliability of information processing. The key contents and technologies of information sharing and collaborative processing mechanism,as well as visualization display are studied,which solves the problems of con- sistency,integrity,current situation and operability of data processing in the whole business process including mobile device applications. The platform and application systems with independent intellectual property rights in China have been developed and applied in Yangquan Coal Industry( Group) Co. ,Ltd. ,Datong Mining Group Co. ,Ltd. ,China Pingmei Shenma Group etc. ,and have been preliminarily realized the new management thought of “ one design,one network,one map,one library” and the high-tech goal of Internet+big data+coal mine.
