Abstract

Joint sets should be considered as an influence factor, when location of subsidence zone by stopes is predicted. And the mechanical properties and distribution patterns of joint set above stopes may be affecting subsidence occurrence. In this study, therefore, the orientation of joint sets is reanalyzed with the data from the previous research on prediction of defining the subsidence zone. From a correlated analysis, the influence of major joint set($J_1$) on subsidence location was analyzed by comparing the angle of assumption with the angle of major joint set($J_1$).

채굴적에 의한 지표에서의 지반침하발생 위치를 추정함에 있어, 절리군은 필수적으로 고려되어야하는 요소 중의 하나인 바, 각 절리군의 역학적 특성과 이들이 채굴적 상부 암반에 분포하는 양상은 지반침하발생을 가속시킬 수 있다. 따라서 본 연구에서는 침하발생 범위의 추정에 관한 선행연구의 근거자료로 이용된 자료 중 절리군의 방향성에 대한 조사정보의 신뢰성이 비교적 양호한 자료들을 선별하여 절리군의 방향성을 중심으로 지반침하 발생위치와의 상관관계를 재검토하였으며, 추정각과 침하 지역에 분포하는 주절리군 $J_1$의 경사각을 비교하여 주절리군 $J_1$이 침하에 미치는 영향을 분석하였다.
