Abstract

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 management platform for underground mines and its potential for enhancing safety through continuous environmental monitoring and remote facility control.

지하 광산은 밀폐된 구조로 인해 유해가스 누출, 붕락 등 중대재해 위험이 크며, 기존 현장 인력 의존형 관리 방식은 신속 대응에 한계가 있다. 본 연구는 ESP32 기반 오픈소스 하드웨어를 활용하여 CO, CO2, NO2, O2를 실시간 모니터링하고, 환기 및 배수장치를 원격 제어할 수 있는 스마트 안전관리 시스템을 개발하였다. CFD 기반 기류 해석 결과를 고려하여 저속 정체 및 재순환 가능 구간을 우선 감시 후보로 선정하고, 현장 설치 가능성과 통신 연결성을 함께 반영해 센서 배치를 결정하였다. 현장 실증에서는 데이터 전송, 데이터베이스 저장, 모바일 화면 표시 및 원격 스위치 조작을 확인하여 제안 시스템의 현장 적용 가능성을 평가하였다.
