Abstract

North Korean mines are known to be vulnerable to mining hazards. This study evaluated the occurrence and diffusion patterns of pollutants in the Musan mine, the largest iron mine in North Korea. Based on the time-series analysis of the Landsat images, continuous mining activities were confirmed. In addition, mining areas were classified using Sentinel-2 images. Areas where pollutants were deposited by the typhoon were identified through InSAR analysis using Sentinel-1 images. As a result of the GIS-based flow analysis, it was confirmed that pollutants can diffuse in four directions and flow into nearby rivers and lower areas. Therefore, in order to prevent the spread of pollutants and pollution of rivers, it is necessary to install facilities in vulnerable areas.

북한의 광산은 시설 노후화와 방지 시설 부족으로 인해 광해 발생에 취약한 것으로 알려져 있다. 본 연구에서는 북한 최대의 철광산인 무산광산을 대상으로 오염물질의 발생 가능성을 평가하고, 이동 경로와 확산패턴을 예측하였다. Landsat 영상의 시계열 분석 결과, 광산의 지속적인 개발을 확인할 수 있었으며 Sentinel-2 영상을 이용하여 광산 영역을 정량적으로 분류할 수 있었다. 또한, Sentinel-1 영상을 이용한 InSAR 분석을 통해 태풍 발생 이후 오염물이 적치된 영역을 파악하였다. 오염물질의 이동경로와 확산패턴을 분석하기 위해 GIS 기반의 흐름방향분석 기법을 적용한 결과, 4개 방향으로 오염물이 확산되어 인근 하천과 광산 남쪽 저지대로 유입될 수 있음을 확인하였다. 따라서 오염물의 확산과 하천 오염을 방지하기 위해서는 유출 가능지역에 확산 방지 시설의 설치가 필요할 것으로 판단된다.
