Abstract: As a core supporting technology for intelligent mining in Coal Mines, transparent geology enables high-precision visualization and dynamic advance prediction for underground complex geological conditions by integrating multi-source geological data of geological exploration, well and tunnel detection, geophysical exploration and drilling, optimizing detection methods and modeling techniques, combining high-precision 3D geological modeling with dynamic updating algorithms. The technology provides reliable geological support for intelligent decision-making in mining processes, disaster risk warning, and collaborative control of mining systems, and is a key foundation for achieving safe, efficient, and green coal mining. On the basis of systematically sorting out the connotation and technical architecture of transparent geological concepts, this paper focuses on the research progress of core key technologies such as multi-source data fusion, fine detection technology, dynamic modeling and visualization, and geological information service platform. Based on typical application cases, the practical effectiveness of transparent geology in intelligent mining, advanced detection of excavation and disaster prevention in working faces was analyzed. this paper deeply analyzes the prominent problems in data standardization, real-time modeling, cross-scale fusion and intelligent decision-making linkage, looks forward to the development direction of deep integration of cutting-edge technologies such as transparent geology, digital twin, artificial intelligence and big data, so as to provide theoretical support and engineering reference for the construction of an intelligent geological support system for coal mines.
