초록
채광작업으로 채굴적의 체적이 증가되어 공동주위에서 응력집중과 응력크기가 변한다. 노출된 표면에서는 풍화가 진행되어 절리표면과 절리의 충전물에서 변화가 일어나 불연속면의 특성이 변한다. 또한 채굴에 따라 반복되는 발파도 암반에 영향을 주고 새로운 균열의 형성과 기존의 불연속면에 영향을 준다. 이러한 영향들이 암반강도의 감소로 이어져 채굴적 주변에서 넓은 범위에 걸쳐 불안정해 질 수 있다. 따라서 지하광산에서의 암반분류법의 적용은 일반적인 터널과는 달리 지하갱도 및 채굴적의 체적, 유지시간, 공동의 수 등은 광산의 수명과 함께 계속적으로 변화된다는 점을 고려해야 한다. 이 논문의 목적은 광산적용 암반분류법이 어떻게 적용되고 있고 차후 국내 광산적용을 위한 암반평가방법에 대한 정보를 제공하고자 한다. 특히 여기서는 MRMR에 대해서는 상세하게 소개한다.
Abstract
With the increase of underground openings caused by mining operations, the stress concentration and stress intensity change around the openings. The weathering makes the surfaces and the filling of joints change the natures of discontinuities. The repetitive blastings also generate new fractures. Since these effects have led to a large reduction in rock strength, the rock mass around the openings may be unstable. Thus, for the application of the rock mass classification system to the mine it should be considered that the volume of underground openings and the number of stopes constantly change with the life of mine. The goal of this paper is to provide the informations of how the rock mass classification is being applied to the underground mining and how it will be applied to the domestic mines in the future. Here, especially the MRMR is introduced in detail.
