GEOCHEMICAL CHARACTERISTICS OF THE ACID MINE DRAINAGE IN THE WATER SYSTEM IN THE VICINITY OF THE DOGYE COAL MINE IN KOREA

摘要

This study investigated geochemical characteristics of the acid mine drainage(AMD) discharged from the abandoned mine adits in the vicinity of the Dogye coal mine in Korea. Acid mine drainage discharged from Jeoncha pit adit of the Dogye coal mine, which is the main source of the AMD in the study area, had a pH value of 3.0 and concentrations of 2148 mg SO~2-_4 L~-1, 229 mg Fe L~-1, 71 mg Al L~-1 and 11 mg Mn L~-1.
