  • The mining-related damages such as ground subsidence, acid mine drainage(AMD), and deforestation in the abandoned underground coal mine areas become an object of public concern. Therefore, the system to manage the miningrelated damages is needed for the effective drive of rehabilitation activities. The management system for Abandoned Underground Coal Mine using GIS includes the database about mining record and information associated with the mining-related damages and application programs to support mine damage prevention business. Also, this system would support decision-making policy for rehabilitation and provide basic geological data for regional construction works in abandoned underground coal mine areas.

  • This research was carried out to investigate chemical pretreatment using lime and limestone in treating abandoned mine drainage with anaerobic treatment. If treating lime with abandoned mine drainage, after 2day, pH was increased to 5.6, and $SO_4^{2-}$, Fe, Al, Pb and Mn were removed 5.7%, 63%, 57, 45% and 28%, respectively. It was estimated that lime dosage was 2,000mg/L for increasing to pH 7. If treating limestone with abandoned mine drainage, after 2day, pH was increased to 3.67, and $SO_4^{2-}$, Fe, Al, Pb and Mn were removed 4.7%, 26%, 22% 18% and 8%, respectively. It could be showed that limestone did slowly react with temperature increasing. If treating anaerobic limestone packing column with abandoned mine drainage, for experimental period, average pH was 4.51, and average $SO_4^{2-}$, Fe, Al, Pb and Mn were removed 4.5%, 15.3%, 20.1%, 23.7% and 5.87%, respectively. So, it would not be suitable for abandoned mine drainage. But if utilizing limestone as pretreatment process for treating abandoned mine drainage with SRB, because it did initally neutralize abandoned mine drainage, it could forward to stabilize system.

  • Batch experiments were performed to evaluate the applicability of soil washing for heavy metal contaminated soils at Nacdong and Hamchang abandoned mines. The texture of the Nacdong soil was sandy loam. Nacdong abandoned mine soil was almost neutral (pH=6.5). Contaminations of As, Cd, Pb and Zn for Nacdong mine soils were 12,900 mg/kg, 29 mg/kg, 696 mg/kg and 276 mg/kg, respectively. Hamchang abandoned mine soils were acidic (pH=2.6) and the soil texture was loam. The contaminations of As, Cd, Pb and Zn for Hamchang abandoned mine soils were 6,410 mg/kg, 291 mg/kg, 1,300 mg/kg and 1,110 mg/kg, respectively. For the Nacdong abandoned mine soils, oxalic acid was found to be the most effective soil washing extracter for As and Pb while citric acid was the most effective extracter for Cd. For the Hamchang abandoned mine soils, oxalic acid showed the highest extraction efficiencies for As and Pb, whilst citric acid presented the best soil washing efficiencie for Cd. Oxalic acid and EDTA were found to be the most effective soil washing extracter for the Hamchang abandoned mine contaminated soils.

  • Among many sources of soil and water pollution, former mining regions also play an important role in distribution and scope of pollution. In response, KMRC has made an investigation into the status mine hazard at the abandoned metalliferous mine area in Korea. In this study, we analyzed distribution of mine hazards at abandoned metalliferous mines using GIS. We considered the distribution of mine hazards and its magnitude for each abandoned mine and displayed the mine hazard index (MHI) using GIS. We divided the MHI value for each mine into 5 classes, and displayed the first class as smallest point symbol and the last class as biggest point symbol. The biggest symbol shows the most serious status of mine hazards. This GIS function was included in the AMGIS system KMRS are running, and it would be helpful to make decision of reclamation priority at abandoned metalliferous mine area.

  • The domestic mine development community the countermeasure establishment is insufficient about ground sinkage, not only the mine which is a in line is partial from the mine of the most which has become the rest mine and abandoned mine or the index sinkage occurs. The ground sinkage which occurs from the abandoned mine area most after operation is stopped, a long time passes and accurately predicts an occurrence location and a time with the residual sinkage which occurs, is difficult. Underground goaf of the abandoned mine and the closed shaft When considering the potentiality which causes the instability of ground, is a possibility of reaching a damage in the ground infrastructure or life. The underground shaft which is formed specially with mine development and goaf operates with the obstacle factor in the development project of the mine area, the ground sinkage which is caused by with sinkage, operates with the large safety accident occurrence factor where the important infrastructure of the railroad, road, residential area etc. is damaged. Therefore, In this paper, the goaf cave of the abandoned mine area, for the displacement behavior according to the filling factor of the material is to analyze the numerical analysis.

  • The objectives of this study were to investigate the effects of soil neutralizing treatments on soil characteristics and growth of Aster koraiensis in the acid soil of abandoned metal mine for selection of proper neutralizer. The most effective neutralizers were acid mine drainage sludge, waste lime + oyster and compost. Those neutralizing treatments showed promoting growth of Aster koraiensis. According to this study, it is applicable of acid mine drainage sludge, waste lime + oyster and compost to neutralize acid soil for rehabilitation in abandoned metal mine. However, follow-up study is necessary to calculate proper ratio of each neutralizer.

  • The Goseong abandoned mine accident was a typical case of long-term sequela resulting from environmental disruption during the rapid economic development of Korea. While the final conclusion of epidemiologic investigation was that residents surrounding the abandoned mine were simply exposed to cadmium from the abandoned mine without any patient contracting 'itai-itai' disease, not only did residents around the abandoned mine suffer enormous psychological and economic damage, but people in neighbouring communities did as well when the entire area was stigmatized as an contaminated area. Environmental civic groups and the government worked together to solve the problem by forming a joint committee which held the right of decision in any matter to be determined. By inviting all the stakeholders to participate in the joint committee, a transparent investigation was guaranteed and the results of investigation and recommendations to solve the problem were accepted by all involved. Even though the environmental health division in Ministry of Environment has developed considerably and built up a capacity to deal with environmental accidents, the process which was adopted to solving the Goseong abandoned mine accident can be useful to settle environmental health issues with severe conflicts among stakeholders.

  • Levels of arsenic in stream and reservoir waters affected by an abandoned gold mine were examined. The abandoned mine has been left without proper civil and remedial works preventing potential environmental hazards. Field and laboratory chemical analyses revealed that the stream waters downgradient from the mine area were severely contaminated with arsenic and furthermore the reservoir water, 2-3 km away from the mine, also contained substantial levels of As, far exceeding the Korean stream water standard. Relatively higher pH values (6.5-9.4) enhanced mobility of As and mainly sustained substantial As concentration in waters. Chemistries of the stream water, groundwater and reservoir water were dominated by two main factors including effects of mine effluent and anthropogenic agricultural activities. Considering that there has been a substantial As input to the reservoir and the reservoir water has been used for agricultural and domestic uses, immediate remedial works are essentially required.
