Abstract: Coal geological guarantee technologies are applied in the whole life cycle of the coal industry. The technologies are the basis and premise of realizing safe, efficient, intelligent and green mining of coal resources, and plays a key role in disaster prevention, hidden disaster-causing factor detection and intelligent mining of coal. Without any doubt, geological transparency is the crucial task to improve the ability of intelligent analysis and decision-making, automatic and precise control, and efficient coal mining. For the purpose of solving the problems faced by Wuhai Mining Area in the construction of coal mine intellectualization, such as complex geological conditions and weak ability of transparent geological support, intelligent detection technologies, represented by seismic detection while excavating and mining, are adopted to acquire the real-time geological data in the mining and excavating working face. On the basis of the results of multi-source data fusion, the 3D geological geometry model and multi-attribute model of water, fire and gas are constructed, and real-time geological data are used to drive the model update to realize digital expression of hidden geological laws and distribution characteristics of structure, water, fire and gas. The transparent geological guarantee system is constructed based on the geological model, integrating the spatial position, geometric size and attribute information of geological anomaly bodies, so as to realize the geological prediction of hidden disaster-causing factors, providing intelligent decision-making for safe and efficient mining of coal mines. The research results provide geological guarantee for realizing the intelligent mining in Wuhai Mining Area and have important referential significance for promoting the intelligent construction of coal mines in China.
