Abstract

One of the most significant environmental issues in abandoned coal mine is acidic drainage which gives rise to the many environmental problems that acidifying streams water, sedimentation of iron/aluminium hydroxide, and pollution of water and soil. Water and precipitate samples for experiments were collected from stream and bottom in the pit mouth of Sambong mine. Mine water shows pH range from 7.24 to 7.94 in winter and 3.87 to 5.73 in summer season. The EC shows range from 432 to $897{\mu}S/cm$ at the stream receiving mine water. The highest concentrations of cations such as Mg, Al, Ca, and Mn are showing 15.50, 4.56, 85.30, 12.76 mg/L in the pit mouth, respectively. The reddish brown precipitates (Munsell color 10R-5YR in winter and 2.5YR-5Y in summer) consist mainly of 2-line ferrihydrite and schwertmannite. The precipitates are characterized by rod or cylindrical forms, and coccus or sphere of 0.1 to $0.5{\mu}m$ in diameter.

폐 석탄광산에서 가장 큰 환경문제는 산성광산배수가 유출되어 주변 하천수의 pH를 낮추고 철/알루미늄 수산화물을 하천바닥에 침전시키며 주변 토양을 오염시키는 것이다. 삼봉광산에서 물시료와 침전물 시료는 갱구 입구에서 채취하였다. 채취한 갱내수의 pH 값의 범위는 겨울에 7.24-7.94이며, 여름에 3.87-5.73이다. 전기전도도는 갱내수가 유입되는 하천에서 $432-897{\mu}S/cm$이다. 갱내수의 Mg, Al, Ca, Mn의 최고 농도값은 각각 15.50, 4.56, 85.30, 12.76 mg/L이다. 적갈색의 침전물은 겨울에는 Munsell color 10R-5YR 정도로 주구성광물은 2-line 페리하이드라이트이며, 여름에는 2.5YR-5Y의 범위로 주구성광물은 슈워트마나이트이다. 주사전자현미경 관찰 결과 침전물은 막대형 혹은 원통형이거나, $0.1-0.5{\mu}m$의 구균형이나 구형을 나타내고 있다.
