A study on the environmental and safety problems and their remediation around mining areas

Abstract

This study was carried out to investigate the problems such as mine drainage, mine wastes, subsidence and existence of facilities at the abandoned metallic mines and to evaluate the reactor system for acid mine drainage treatment in the field. According to the field investigation, the remediation was necessary for abandoned mines such as the Taechang, the Imcheon, the Kubong, the Cheongyang, the Cheonbo(Jungyang), the Seojeom, the Kuryong and the Ilkwang mines. Comparing analytical data with soil environmental reservation law, main components to contaminate soil environment in the vicinity of the abandoned mining areas, were As, Cd, Pb and cyanide. Results of chemical analysis for mine drainage showed that As Cd, Cu, Mn, Zn, Cr{sup 6+}, Fe and pH were major pollutants to the water environment and over level of discharge, water quality environment reservation law. The reactor with cow manure removed the metals such as Fe, Cu, Zn, Cd, Pb and Al by 100%. It was evaluated that the metal removal in the reactor was due to sulfate reduction and hydrolysis. In addition, acid mine drainage was neutralized to over pH 5 during 100 days. (author). 12 refs., 25 tabs., 23 figs.
