Abstract

In this paper, we investigated the subsidence possibility and countermeasures according to the current mining method through investigation of the subsidence condition in operation mine. Most of the metal mine were broken, investigating to subsidence pattern of the Sink-hole. Coal mines are becoming more and more deep, investigating to Trough type subsidence patterns in existing mining areas. History of nonmetallic mines have not been developed for over 30 years, but large and small ground deformation problems have been investigated. Mining also has ground subsidence functionality due to time dependence by relying more heavily on empirical methods than technical methods. Therefore, it is necessary to carry out the various researches on systematic development method and prevention of subsidence of nonmetallic mines.

가행광산 지반침하 실태조사를 통하여 현 채광방법에 따른 지반침하 가능성과 대책을 분석하였다. 금속광산은 대부분 휴·폐광 상태로서 싱크홀의 침하양상을 나타내고 있다. 석탄광은 점점 더 심부화 되어가고 있으며, 기존 채광지역에서 트러프형의 침하양상을 보였다. 비금속 광산은 대규격 광산개발 이력이 30년 이내로서 크고 작은 지반변형의 문제가 조사되었다. 채광 또한 기술적 방법보다 경험적인 방법에 더 의존함으로써 시간 의존성에 따른 지반침하 가능성이 상존하였다. 따라서 비금속 광산 위주의 체계적인 개발방법과 지반침하 방지에 대한 다양한 연구가 수행 되어야 할 것으로 본다.
