Zusammenfassung:In this study, a survey of structural geology and discontinuities were carried out on the space in a limestone mine where the construction of crushing facilities is in planning. The stability of the site was analyzed by rock mass classifications and numerical analysis. Through these analyses, it could be known that removal of pillars could make the stability problems in the mine and the supports for pillars must be considered. 파쇄시설의 갱내 구축을 검토 중인 석회석광산의 예정 부지에 대한 지질조사, 불연속면조사를 실시하고 암반분류와 수치해석을 통해 안정성 평가를 수행하였다. 공간 확보를 위한 광주의 제거는 채굴 갱도의 안정성을 저하시킬 것으로 판단되며 광주의 내압강도 증가를 위한 보강이 필요할 것으로 나타났다.
