초록

국내의 많은 지역에서 골재 채취가 이루어지고 있으며 이로 인해 대형 절토사면이나 다량의 절취된 암석이 발생되고 있다. 이러한 골재 채취를 위한 개발부지가 황화광물이 수반된 지층일 경우 산성암석배수(Acid Rock Drainage : ARD)가 발생하여 개발부지 내와 주변지역에 환경오염의 문제를 발생시킬 수 있다. 산림골재 시료를 대상으로한 연구결과 시료 대부분이 잠재적인 비산발생 시료로 분류되고 그중에 광주시, 고양시, 속초시의 일부 시료에서 잠재적인 산발생 시료로 분류되어지는 결과를 얻었다. 이는 향후 다량의 골재가 사용될 경우 골재의 품질에 영향을 줄 수 있음을 예상할 수 있다. 따라서 이러한 산림골재들은 사용 시 관리가 필요할 것으로 판단된다. 산 발생 능력 시험을 통한 ARD 발생 예측으로, 향후 발생 될 수 있는 경제적 손실을 줄일 수 있을 것으로 기대되며, 주변 환경오염 문제를 보다 완화 시킬 수 있을 것으로 판단된다.

Aggregate collection is taking place in many areas in Korea, resulting in large cut slopes or large amounts of cut rocks. If the development site for such aggregate collection is a stratum accompanied by sulfide minerals, Acid Rock Drainage (ARD) may occur, which may cause environmental pollution in the development site and surrounding areas. As a result of the study on forest aggregate samples, most of the samples were classified as acid-forming potential samples, and among them, some samples from Gwangju, Goyang, and Sokcho were classified as potential acid-generating samples. This can be expected to affect the quality of aggregates when a large amount of aggregate is used in the future. Therefore, it is judged that these forest aggregates need to be managed when they are used. By predicting the occurrence of ARD through the acid-generating ability test, it is expected that economic losses that may occur in the future can be reduced, and it is judged that the problem of surrounding environmental pollution can be further alleviated.
