A Review of the Application of Electric UAV Fusion Intelligent Sensor Technology in Coal Mine Safety Mining

Coal, as a globally critical strategic resource, demands secure and stable production. However, the complex and harsh mining environment renders traditional manual operations inefficient and highly risky. With advancements in robotics, electric Unmanned Aerial Vehicles (eUAVs) have enabled non-contact operations, offering flexible and rapid deployment capabilities. Combined with multi-source data fusion from smart sensors they carry, eUAVs have significantly enhanced efficiency in exploration, inspection, and rescue missions. This review examines the current state of eUAVs integrated smart sensor technologies and analyzes their specific applications in mine safety production, including surface hazard monitoring and underground exploration and rescue operations. It emphasizes key challenges, such as robustness testing in complex environments. It also points out the new opportunities of reliability research and deep learning integrated application research in the field of coal mine safety mining. The fusion of eUAVs and smart sensor technology not only improves the monitoring efficiency per flight mission but also expands sensor data sources. This effectively advances mine intelligence capabilities, provides new safeguards for coal mining safety, and represents a crucial direction for the development of smart mines.
