Abstract: To solve the many problems in the mine current geological data by way of mining information system engineering, the geological database of Makeng Iron Mine was established by SURPAC platform-based comprehensive analysis of the large amount of geological exploration data accumulated in the mine's many years' mining and supplementary exploration, standardization of the initial geological data, definition of four geological data structural tables and data entry of 85 effective drill-holes in the whole mining area, thus providing important basic data for the mine's rational mining and scientific policy-decision.

Key words: SURPA, Geological database, Drill-holes, Digital mine
