Abstract: In response to the challenges of complex geological conditions and dynamic changes in the supercritical CO₂（SC-CO₂） jet mining process, this paper studies the dynamic update method of 3D geological models and the development of a visual management and control platform. By integrating multi-source geological data and real-time monitoring information, a multi-field coupling model based on numerical manifold method is constructed to achieve dynamic simulation of the entire thermal mechanical chemical（TMC） process of geological structure, stress field, and seepage field. The platform adopts HOOPS Visualize engine and WebGL technology to develop a visual management and control system with 4D spatiotemporal features, supporting real-time monitoring, analysis, and optimization of SC-CO₂ jet operations.
