이 연구에서는 옥동광산 광물찌꺼기 적치장을 대상으로 IoT 기술을 활용한 실시간 모니터링 시스템을 구축하고 옹벽 구조물 변화 및 침출수 유출량 등을 확인하여 계측기기의 현장 적용 가능성을 평가하였다. 구조물 경사계의각도 변화는 계절 및 온도 변화에 따라 X축, Y축 경사가 모두 변화를 보였다. 이는 수축·팽창에 의해 구조물 길이가미세하게 변화되는 것으로 그에 따라 각도가 변화하고 있다. 침출수의 유량변화는 강우에 따라 증감하고 있으며, 건기에도 침출수가 지속적으로 유출되고 있어 관리가 필요한 실정이다. 향후 추가 계측기기 설치 및 계측기기별 축적된데이터를 활용하여 예보·경보등급 설정 등을 마련하면 최적의 적치장 안전관리를 할 수 있을 것으로 판단된다.
Abstract
In this study, a real-time monitoring system using IoT technology was established in a tailings dam of the Okdong mine, and the structural variation of the retaining wall structure and the leachate flow rate from the dam were examined to evaluate the field applicability of the measuring equipment. The slope of the structure’s inclinometer showed change of both the X-axis and Y-axis inclination with the change of seasons and temperature. This might have been due to slight change caused by shrinkage and expansion of the structure length, resulting in variation of those angles. Variations in the flow rate of leachate from the dam resulted from increased precipitation amounts in the rainy season and decreased amounts in the dry season, although leachate was flowing out continuously. In the future, both the establishment of forecast and alarm grade systems and the installation of additional measuring devices along with the data accumulated from them will enable optimal safety management in tailings dam sites.
