Abstract: Coal mmes are hazardous working environments where the presence of toxic gases, oxygen-deficient atmospheres, high temperatures, and humidity variations can pose serious risks to worker safety. Conventional monitoring methods often rely on manual inspections, which may expose personnel to dangerous conditions and fail to provide continuous environmental surveillance. To address these challenges, this project proposes an loT-Based Smart Coal Mine Safety Monitoring and Inspection System Using LoRa Communication for real-time environmental monitoring and hazard detection. The proposed system integrates multiple environmental sensors, including gas sensors for detecting harmful gases, an oxygen sensor for measuring air quality, and a DHTII sensor for monitoring temperature and humidity. An ESP32 microcontroller acts as the central processing unit, collecting and analysing sensor data. To minimize human exposure to hazardous !~cations, the sensing unit is mounted on a mobile robotic platform driven· by DC motors, enabling remote inspection of underground mining areas. The collected environmental data is transmitted wirelessly through LoRa communication technology to a Node MCU-based receiver unit. The received information is uploaded to a cloud-based loT platform, allowing mine operators and safety personnel to monitor environmental conditions remotely through a real-time dashboard. The system also incorporates automatic hazard detection and alert mechanisms to notify users when unsafe conditions such as toxic gas leakage, oxygen deficiency, or abnormal temperature levels are detected. By combining environmental sensing, robotic mobility, loT connectivity, and long-range wireless communication, the proposed system provides a reliable, cost-effective, and scalable solution for enhancing mine safety. The system reduces worker exposure to hazardous environments, enables early detection of dangerous conditions, and supports safer and more efficient coal mining operations.
