초록

폐광산에서의 지표침하의 영향범위를 추정하기 위하여 많이 적용되어 왔던 도식법은 수평탄층에서 흔히 발생하는 트러프형 침하의 영향범위를 추정하는데 그 적용성이 높은 것으로 알려져 왔다. 그러나 국내 광산의 광체들은 대부분 급경사이며, 침하 형태 또한 함몰형의 빈도가 상대적으로 높은 것으로 보고되고 있기 때문에, 국내 침하지에 도식법을 직접적으로 적용하는 것은 바람직하지 않다. 따라서 본 연구에서는 국내 폐광산 지역에서 발생한 총 163개의 지표침하 발생지에 대한 사례분석을 실시하여, 채굴적의 위치를 기준으로 광체의 경사방향 및 광체의 경사반대방향으로의 지표침하 발생범위를 규명하였다. 또한 이를 토대로 채굴적의 심도를 고려한 지표침하 발생범위에 대한 추정각을 산정하였으며, 기존의 도식법과의 비교분석 및 지표침하 발생 사례 적용분석을 통해 최종적으로 이 추정각의 범위를 제안하였다.

Graphical method has been widely applied to the prediction of subsidence area, and is known to have advantages in analysis of trough subsidence which is common in horizontally seamed mine area. However, it is reported that most of the ore bodies in Korea are geologically inclined from sub-horizontal to steep, and therefore, the sinkhole subsidence is frequent in abandoned mine area. For these reasons, it is not to be desired that graphical method is applied for predicting the subsidence occurrence. This paper describes the results of subsidence zone prediction considering the dip direction and the opposite direction of inclined ore bodies from the case studies on the 163 subsidence occurrence regions. The results show also the assumed angle which can define the range of subsidence in the surface area. In conclusion, the limit of this angle is suggested after taking into account the comparison with graphical method and the application to the case histories.
