With the advancement of intelligent underground operations, there is an increasing demand for efficient and reliable communication systems. The collaborative networking of multi-mode communication (UWB/fiber/5G) has become crucial for addressing communication challenges. This study analyzes the characteristics of UWB positioning and communication, fiber transmission, and 5G communication. It explores collaborative network architecture design, investigates adaptive switching mechanisms for different communication modes, and examines key technologies such as signal interference suppression and synchronization. Through this research, seamless coverage and high-speed stable transmission of underground communications are achieved, meeting diverse operational needs while supporting safe production and intelligent operations in underground environments. This work drives technological innovation in underground communication systems.
