Key Technologies and Implementation of a Digital Twin-Driven Shuttle Car Operation System for Coal Mines

To address the efficiency bottlenecks and safety hazards inherent in traditional operational modes of coal mine shuttle cars, while improving the excessive reliance on manual labor and insufficient intelligent capabilities, this paper proposes a digital twin-based operational system for coal mine shuttle vehicles. The system constructs a digital model of shuttle vehicles and enables bidirectional synchronicity through MQTT -based transmission of virtual-real twin data, achieving accurate virtual mapping of shuttle equipment. This implementation provides personnel with explicit real-time monitoring of transportation processes, thereby facilitating enhanced operational decision- making for shuttle control. Enterprise-conducted simulated field tests demonstrate the system's practical applicability in effectively improving safety and operational efficiency in coal mine transportation. This study not only validates the practical implementation value of digital twin technology in mining transportation equipment but also contributes to the future development of intelligent and unmanned operations in coal mine transportation systems.
