| 초록 | 1999년도에는 광해발생정도가 심한 광산지역의 4개 광산(임기광산, 덕음광산, 서성광산, 전주일광산, H.D. 노천광산)의 광해를 조사하였고, 광해예방 및 대책을 위한 실내시험 및 현장실증시험(광산배수 자연정화처리 시 소택지에서의 Flow system 시험연구)을 실시하였으며, 산림훼손 방지 및 광해방지를 위한 노천채광법에 관하여 연구하였다 The remediation or prevention of environmental problems and hazard around mining areas is required to prevent the natural environments and to protect human health. A survey were carried out to exam the characteristics of abandoned mines and to delineate contaminated sites in 4 abandoned mines (Image mine, Duckeum mine, Seosung mine and Jeonjuil mine). Permeability experiment was carried out to resolve clogging problems in passive treatment system. Absorption and desorption experiment was carried out to evaluate algae's ability for eliminating metals in mine drainage. In addition, a research on optimal mining method for reducing the area of forest damage in open pit mining areas was carried out. Mine drainage from the waste rock spoil in the Imgee mine was contaminated by F, Cd and Fe and was acid water. In case of the Duckeum mine, mine drainage near the tailings impoundment was acidic. Zinc contents in the mine drainage were more than tolerance level. The mine drainage from the adit in the Jeonjuil mine has contaminated by F. Results of soil analysis revealed that soils around the Duckeum mine and the Seosung mine were contaminated by Pb, Cd and As, Cd, Pb respectively. Results of permeability experiment showed that the coefficients of permeability of oak chips mixed with crushed limestone and coarse sand were 4.2 x 10 -2cm/sec and 2.3x10 -2cm/sec, respectively. As mine drainage upflowed through the column, metal hydroxide was intensively accumulated near the inlet and the outlet of columns. These phenomena contributed to lower the coefficient of permeability and caused clogging in columns. Further study on the optimal mixture of substrates for maintenance of constant flow and treatment for mine drainage in the wetland system will be required in order to prevent clogging caused by precipitation of metal hydroxides. The absorption test of algae for metals revealed that algae absorbed Fe, Cu and Al. Manganese was absorbed to the extend of 0.3 wt.% of dry algae. Therefore algae amy be used for removal of Mn in passive treatment system. Plan Cut method was more superior to Bench Cut method in that the former could minimize the area of forest damage and reduce the mining environmental problems |
