There is no unified principle for the description and storage of metadata in the current information system which the coal mine enterprise exists in, neither does it benefit the management and maintenance of system, nor the integration with other system. According to the standards of relevant metadata and the characteristic of coal and gas outburst factors data, this paper proposed the data storage framework. The metadata obtained is described by the Unified Modeling Language (UML), and part of datasheet in a coal mine are described practically, it makes good preparation for the establishment of data warehouse.
