Abstract

This study reviewed the accumulation status of waste rock generated while mining domestic limestone and dolomite mines. Potential utilization plans for the waste rock have been discussed. Data on the annual production and waste rock generation for the past five years were obtained from 47 currently operating mines. In addition, waste rock samples were collected from eight mines in the Gangwon and Chungbuk regions to investigate their chemical and mineralogical characteristics. For underground mining, waste rock generation accounted for approximately 9% of total ore production; in open-pit mines, it was up to 24%. Mine water both inside and outside the pit was analyzed and was found to meet general water quality requirements except for the suspended matter concentration. The mechanical test results showed that the generated waste rock met quality standards and could be used as coarse aggregates for concrete production.

이 연구에서는 국내 석회석 및 백운석 광산의 채굴과정에서 발생하는 부산물의 관리 현황과 활용 방안에 대하여 검토하였다. 현재 가행 중인 47개소 광산을 대상으로 설문조사를 통하여 최근 5년간의 생산량과 부산물 발생량 자료를 취합하였으며, 강원 및 충북 지역의 8개 광산 현장을 방문하여 부산물의 적치현황과 화학적, 광물학적 특성을 조사하였다. 갱내채광 광산의 경우 생산량 대비 9%, 노천채광 광산은 24%의 부산물이 발생하고 있었다. 갱내수와 갱외 유출수의 수질은 부유물의 농도 외에는 일반적인 방류수질 기준을 만족하는 것으로 분석되었다. 또한 역학 시험의 결과에서는 굵은 골재의 품질기준치를 충족하여 콘크리트용 골재로서 활용가능성도 높음을 확인하였다.
