摘要:Abstract(#br)In assessing the adverse effects of acid mine drainage (AMD), the chemistry of AMD and stream water (i.e., pH and toxic metal concentrations) has been accounted as important monitoring parameters and its characteristics are regulated in many countries. Yet for the pr...

摘要:Abstract(#br)This study surveyed and investigated the deformation of the coal waste dump slope and the natural ground slope under the waste dump at Dogye village in Samcheock city, Gangwon Province, Korea. Multiple sets of south-north tension cracks were observed at the cres...

摘要:Abstract(#br)During large constructions of roads or structures, unexpected acid rock drainage (ARD) can be caused by local mineralization containing sulfides in the geology. The potential of ARD occurrence of a certain area sometimes must be assessed before initiation of any...

摘要:Abstract(#br)A logistic regression model for the probability of arsenic exceeding the drinking water guidelines (10 μg/L) in bedrock groundwater was developed for a selected county in Korea, where arsenic occurrence and release reactions have been investigated. Arsenic was e...

摘要:Abstract(#br)Because of the risk of diminishing supplies of rare earth elements (REEs) worldwide due to China’s dominance over REE supply, the necessity of developing domestic resources of REE has been realized in other countries. To explore new ore bodies, a geochemical sur...
