Research and Application of Digital Twin System for Two Passages in Coal Mining Longwall Face
Abstract：Based on digital twin technology, this study designed and developed the architecture and functions of a digital twin system for two passages in a coal mining longwall face, using methods such as multi-source data fusion, 3D modeling, and dynamic simulation. A five-layer system architecture was constructed, including the physical layer, perception layer, network layer, platform layer, and presentation layer. Sensors were used to collect real-time data on equipment operation and environmental conditions, which were transmitted via 5G networks to the platform layer for analysis and processing, and then generated a full-element virtual scenario in the presentation layer. Functional modules such as global equipment overview, unit operation monitoring, fixed and free patrol modes were developed, achieving three-dimensional visualization of equipment status, fault early warning, and remote maintenance management. Application cases show that in Xiaobaochang Coal Mine, key data dynamic monitoring and intelligent early warning were realized, reducing the number of personnel for face inspections, and improving the level of intelligence and safety assurance in coal production.
