Abstract: Through analyzing the existing problems of map management of digital mine in China, combined with the development trend of international geographic information system and the specific requirements of safety production management platform of Yangquan Coal Industry Group, “one map” management theory is proposed in this paper, and the corresponding information management mode and technology system is studied and applicated in detail. Practice has proved that the management and technical methods of “one map” meet the requirements of data processing and visualization in intelligent mining area.
