Information
This study was performed to find the way that is alternative utilization of the drift that had been abandoned by coal industry promotion. To determine whether abandoned drift would be maintained without supports or not, the safety inspection that consists of drift survey, laboratory tests, rock mass classification and numerical analysis was performed. According to the result, there were discontinuity sets those had unfavorable orientation to the drift and rock mass around the drift had generally poor condition. So, it would be much difficult that abandoned drift is maintained without supports.
본 연구는 석탄산업합리화로 인해 폐광된 갱도를 재활용하기 위하여 폐갱도를 무지보 혹은 국부적인 재래식 지보만으로 활용하는 방안에 대한 가능성을 파악하는데 그 목적이 있으며, 이를 위하여 갱내 불연속면조사, 현지 암반분류, 실내시험, 수치해석 등을 통한 안전진단이 실시되었다. 갱내 불연속면조사 결과 폐갱도에 불리한 조건으로 작용하는 불연속면군들이 조사되었고, 현지암반 분류 및 수치해석 결과 폐갱도 주변 암반이 대체로 불량한 것으로 나타나 폐갱도를 무지보 혹은 국부적인 지보만으로 유지하여 이를 재활용하기에는 어려울 것으로 판단되었다.
