Abstract: With the deepening of the construction of smart mines，the traditional centralized cloud computing architecture faces challenges such as response delay and insufficient computing power in massive heterogeneous data processing. An intelligent mine data processing system architecture based on edge com⁃ puting technology is proposed. Through the sinking of computing resources and distributed intelligence，the real-time monitoring，efficient processing and safe storage of mine environmental data are realized. The sys⁃ tem adopts a three-tier distributed architecture，including smart terminal layer，edge computing layer and smart cloud. The intelligent terminal layer ensures the reliability of data transmission in complex environ⁃ ments through multi-network fusion technologies (LoRaWAN，WIFI，5G/4G and Beidou satellite communi⁃ cation). As the core hub，the edge computing layer relies on the edge gateway to realize data acquisition， preprocessing，anomaly detection (such as isolated forest algorithm) and local storage，which significantly reduces latency and improves security. The smart cloud integrates multi-source data and supports decision management through a visual interface. Typical application scenarios (environmental monitoring，slope warn⁃ ing，and personnel positioning) verify the effectiveness of the system in improving production efficiency and ensuring safe production. The edge computing technology can effectively solve the problems of real-time， stability and security of data in the construction of intelligent mines，and provide an innovative solution for the intelligent transformation of mines.
