ZigBee 기반 실시간 가스 모니터링과 CFD 기반 센서 배치를 활용한 지하광산 원격 안전관리 시스템 개발

초록

Owing to their confined environments, underground mines are highly vulnerable to accidents such as hazardous gas leakage and roof collapse. Moreover, the rapid detection and response of conventional safety management systems relying on on-site personnel remain limited. This study developed an ESP32-based smart safety management system capable of the real-time monitoring of CO, CO2, NO2, and O2 concentrations and remote control of ventilation and drainage facilities. Sensor locations were determined using Computational Fluid Dynamics (CFD) based airflow analysis combined with field installation feasibility and communication connectivity. Field validation further confirmed real-time data transmission, database storage, mobile monitoring, and remote switching functions. In summary, these results demonstrate the feasibility of a low-cost Internet of Things (IoT) based safety manage ment platform for underground mines and its potential for enhancing safety through continuous environmental monitoring and remote facility control.
