  • According to the policy of coal industry promotion, a lot of mines were abandoned. As the abandoned mines were neglected, environmental pollution such as settlement of ground, ground-water run-off, landscape damage etc were accompanied around abandoned mines. The government was promoting countermeasures of environmental contamination but most of the Countermeasures were aimed at protecting the ecological system not infrastructure. For this reason, abandoned mines impact on infrastructure has been relatively neglected. Most mines are located in mountainous so there is a tunnel among typical infrastructure around abandoned mines. In this paper, the effect of Mine drainage, Typical pollution source of abandoned mine, was introduced into the using tunnel focusing on the types and examples.

  • Background: Abandoned metal mines are classified as vulnerable areas with the highest level of soil contamination among risk regions. People living near abandoned metal mines are at increased risk of exposure to toxic metals. Objectives: This study aimed to evaluate the correlation between soil contamination levels in areas around abandoned metal mine and the blood lead levels of local residents. Moreover, we assess the possibility of using soil contamination levels as a predictive indicator for human exposure level. Methods: Data from the Survey of Residents around Abandoned Metal Mines (2013~2017, n=4,421) and Investigation of Soil Pollution in Abandoned Metal Mines (2000~2011) were used. A random coefficient model was conducted for estimation of the lower level (micro data) of the local resident unit and the upper level (macro data) of the abandoned metal mine unit. Through a fitted model, the variation of blood lead levels among abandoned metal mines was confirmed and the effect of the operationally defined soil contamination level was estimated. Results: Among the total variation in blood lead levels, the variation between abandoned mines was 18.6%, and the variation determined by the upper-level factors such as soil contamination and water contamination was 8.1%, which was statistically significant respectively. There was also a statistically significant difference in the least square mean of blood lead concentration according to the level of soil contamination (p=0.047, low: 2.32 ㎍/dL, middle: 2.38 ㎍/dL, high: 2.59 ㎍/dL). Conclusions: The blood lead concentration of residents living near abandoned metal mines was significantly correlated with the level of soil contamination. Therefore, in biomonitoring for vulnerable areas, operationally defined soil contamination can be used as a predictor for human exposure level to hazardous substances and discrimination of high-risk abandoned metal mines.

  • Industrial heritage artifacts may include the industrial products, technologies and infrastructures that have contributed to modernization beginning with the Industrial Revolution. The history of our industrial heritage spans 50 to 150 years and can be characterized by taking into account the site and the technology. This paper analyzes 13 precedents in Japan, Canada, and the United States in terms of these concerns, with focus on the reuse of abandoned mines as industrial heritage. Field surveys and interviews about each abandoned mine were used to obtain historical records and material. The results describe progress in three phases (1) recognizing phase, (2) organizing phase, and (3) maintenance management phase. A proper methodology for reuse is necessary to ensure the authenticity of the abandoned mine, particularly in the face of poor tourism-oriented approaches. As a result of analyzing the 13 cases, we determined that the following principles should be considered during the reuse process. Firstly, reuse of abandoned mines should not be compulsory but should be a spontaneous process and especially, should be carried out by inhabitants. Secondly, education and real experiences in the abandoned mine should be used to ive visitors a feeling of authenticity. Thirdly, creative remodeling methods can be used to enhance the abandoned mine's facilities and the site. Finally, historic and new functions should be the focus of the revitalization. Because this paper mainly focused on 13 precedents, there are likely more diverse cases. However, the conclusions of this report have practical value for reuse of abandoned mines and can be used in establishing methods for reusing Korean abandoned mines as industrial heritage.

  • There are approximately 2,000 metallic mines which have been abandoned in Korea. Most of the mines are located in the watershed area, which is main source of drinking water for Seoul Metropolitan area. Untreated mining wastes are remained around abandoned mines in study area. These mining wastes, flowing into farmland and stream in the downstream of abandoned mines, would cause water and soil pollution. The mining waste samples from Guedo mine, Manjung mine and Joil mine recently abandoned were collected for the evaluation of the potential of water pollution by mine waste. Index of geoaccumulation($M\"{u}ller$, 1979), fractional composition and removal efficiency of some heavy metals by different concentration of HCl treatment were analyzed. Index of geoaccumulation of Cd, Pb, Zn, Cu, Ni and Cr are 6, $4{\sim}6,\;0{\sim}6,\;4{\sim}5$, 2 and 0 respectively. Index of geoaccumulation of Cd, Pb, Zn and Cu reveals the mining wastes has high pollution pottential in the area. Organic fraction of Cu, reducible fraction of Pb, residual fraction of Ni and Zn were the most abundant fraction of heavy metals in mining wastes.

  • Heavy metal contamination and biological toxicity of mine drainages and sediments in abandoned mines were studied. Mine drainages had pH at a range of 2.94~7.86, and contained heavy metals at a toxic level. For coal mines, toxicity of mine drainage to Daphnia magna was attributable to acidic pH. In addition to the low pH, suspended heavy metals such as Zn and Cu contributed to toxicity of mine drainages at abandoned metalliferous mines. All mine sediments studied in this work showed biological toxicity to Chironomus riparius, having mortality at a range of 15~60%. However, its relationship with physicochemical properties including heavy metal content of the sediments was not statistically explained. Exceptionally clay ($< 2{\mu}m$ particle) content was negatively correlated with the biological toxicity for sediment samples collected at the same abandoned mines.

  • The risk assessment for heavy metal pollutions were analyzed by using statistical techniques including correlation and cluster analyses. The contamination data in this investigation obtained were from the Chungcheongnam-do abandoned mines. The descriptive statistical analysis showed that the values of Pb and Zn were relatively higher than other heavy metal values. The detection of heavy metals by distance from abandoned mines within 1,000m were mostly As, Cd, Pb, and Zn. It was noted, especially, that Zn was even detected at 4,000m The results of coefficient correlation showed that Zn to Cd was the highest values. The cluster and dendogram analyses were generated. The results showed the two clear groups by heavy metal characteristics.

  • This study was conducted to estimate the status of heavy metal contamination in agricultural products (n = 280), soils (n = 280), and irrigation waters (n = 48) in abandoned mines & normal farm lands (n = 8). The samples were digested with acids, then analyzed fur the contents of lead (Pb), cadmium (Cd), copper (Cu), mercury (Hg), arsenic (As) and chrome (Cr) by an inductively coupled plasma spectrometer (ICP) and graphite- atomic absorption spectrophotometer (AAS). The contents of Hg were determined using a mercury analyzer. Abandoned mines had soils with higher contents of heavy metals except Cr and irrigation waters with higher heavy metals except Hg, compared to those of normal farmlands. The contents of heavy metals in agriculture products varied depending types of products. Agricultural products in abandoned mines generally showed with higher contents of heavy metals except Cu, compared to those of normal farmlands. There was no significant relationship in heavy metal contents between agricultural products and soils (p > 0.05). It is suggested that heavy metals of agricultural products and soils in abandoned mines should be continuously monitored.

  • There are approximately 500 abandoned mining sites in Korea. Abandoned mines cause various environmental and safety problems such as landscape damage, soil, groundwater and stream pollution by heavy metal, acid mine drainage and soil erosion. According to the survey, there are significant numbers of mines causing environmental problems in Korea. For a environmentally sound management of abandoned mines, the Soil Pollution Control Act should include the regulation concerning soil pollution and recovery standards of the abandoned mines. Also, comprehensive survey about abandoned mines, setting-up of tile recovery priority, finance for clean-up are necessary.
