In order to solve the problems of complex multi-source data management, insufficient intelligent graphics rendering, low system integration and abstract results expression in coal mine underground drilling and geophysical exploration engineering, a "two-exploration" data fusion application system for transparent geological construction is constructed. A dual-engine architecture based on multi-dimensional cloud GIS platform and 3D model cloud rendering platform is proposed, and a two-3D integrated transparent geological support system including "digital-graphic-mode" triple linkage mechanism is developed. Through the establishment of a unified data center, the standardized filling and reporting of the "two-probe" data of 14 mines was realized, the geological attribute field was constructed by the improved anisotropic inverse distance weighted interpolation algorithm (AIDW), the high-precision modeling of geological bodies was realized by combining the Loop subdivision surface optimization technology, and the differential linkage model of drilling parameters and the three-dimensional picture space mapping algorithm were innovatively designed. The application shows that the system can increase the interpretation efficiency of geophysical exploration results by 40%, reduce the design time of water exploration and drainage holes by 65%, control the response time of 3D seismic data cutting analysis within 200ms, and the accuracy rate of hydrogeological anomaly identification reaches 92%. The triple linkage mechanism and spatial interpolation optimization algorithm proposed in this paper effectively solve the technical bottleneck of "two-probe" data fusion modeling in coal mines, and provide a scalable geological transparency solution for the construction of intelligent mines.
