Abstract: In order to improve the intelligent level of mine construction in Daheng Coal Industry, aiming at the main problems existing in the intelligent construction, the goal of intelligent mine construction based on GIS （geographic information system） is put forward. The basic framework and key technologies of intelligent system based on GIS are analyzed. The intelligent system of “one map integration” based on GIS technology is established and applied in Daheng Coal Industry. The results show that by integrating multi-source information, a variety of data processing and storage are completed; a high-precision three-dimensional model of three-dimensional space framework, coal seam occurrence form and geological structure distribution of the whole mine is constructed. By establishing the real-time mapping relationship between the mining progress and the model data, the synchronous matching between the model update cycle and the production progress is realized.
