Abstract

Mine leachate discharge from mine waste rocks and tailings can cause many environmental problems when it is transported to soils and streams around mining areas. The purpose of this study is to analyze the mine leachate pathway with time using Geographic Information Systems (GIS). Digital Elevation Model (DEM), soil map, and land cover map were used to account for the effective rainfall and temporal variation of surface discharges. A new method which considers the measured hourly rainfall data was proposed to analyze the water level fluctuation and mine leachate migration. The application to the Samgwang mine showed that mine leachate from some areas with tailings-impoundment can flow into the Sindae reservoir. It is expected that the proposed method can be effectively used to analyze and prioritize the areas where detailed investigation is required for mine reclamation.

광산폐기물로부터 발생한 침출수는 광산지역 인근의 수계와 토양으로 유입되어 다양한 환경적 문제들의 원인이 될 수 있다. 본 연구의 목적은 GIS를 이용하여 광산폐기물에서 발생하는 침출수의 시간에 따른 이동경로를 분석하는 것이다. 수치지형모델, 토양도, 토지피복도 등의 자료를 사용하여 유효강우량과 유출량의 변화를 설명하고, 시간경과에 따른 수위변화와 침출수의 이동경로를 분석할 수 있는 새로운 기법을 제안하였다. 충청남도 삼광광산에 대해 사례연구를 수행한 결과, 강우시 광산폐기물로부터 발생한 침출수가 신대저수지로 유입되는 경로를 시공간적으로 분석할 수 있었다. 본 연구에서 개발된 기법은 광해방지사업 추진시 수질 및 토양의 정밀 오염조사가 필요한 지역들을 선정하는데 유용하게 활용될 수 있을 것이라 기대한다.
