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, through the integration of multi-source information, various types of data are successfully processed and stored. A high-precision three-dimensional model is constructed for the entire mine, including the spatial framework, the occurrence morphology of coal seams in working faces, and the distribution of geological structures. By establishing a real-time mapping relationship between mining progress and model data, the model update cycle is synchronized with the actual production schedule.
