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.

The price fluctuation of minerals are commonly occurred through the change of market condition, and the redevelopment of closed mines are usually happened if commercial requirement can be satisfied. After 2003, as the price of most of metals increased very rapidly, Korea government tried to find the possibility of reopening for some closed metal mines. The purpose of this article is to suggest the proper ways how effectively to regulate the mine pollution concerning the redevelopment of closed mines. For this work, with the recent price trends of metals and reopening possibility of closed metal mines in Korea were reviewed. And analysing the problems of regulations for the mine development permission and mine pollution control and reclamation process of Korea, several amendments of environmental and mining regulation regimes for redevelopment of closed mines were proposed.

This study was conducted to figure out measures to improve abandoned mine area residents' life satisfaction from the viewpoint of ecosystems. The subjects of this study were 195 residents aged at least 30 years and structured survey were used collected from April, 3, 2014 to 20. The levels of abandoned mine area residents' mental health were measured using the general mental health scale and the residents' life satisfaction was examined using a life satisfaction scale. The abandoned mine area resident's life satisfaction was a little higher than the middle and their future life satisfaction was shown to be the lowest. Out of the microsystemic factors, mental health degree contributing to the quality of life and those with lower depression and anxiety showed higher life satisfaction. None of the mesosysystemic factors, were not found to influencing the quality of life. Out of the macrosystemic factors were found to be mine area special law in influencing the quality of life. In order to improve the life satisfaction of the mine locals seem to need practical strategies related for maintaining a healthy mind and continued implementation of the economic revitalization policy.

The main reason of the pollution caused by soils and tailings located at discussed mines is heavy metals and AMD(acid mine drainage). Human health is affected by these pollutants which are spreaded from the abandoned mines. In this study, we try a mathematical approach to predict the pollution level of heavy metals caused by the surrounding soils of abandoned mines. The new approach is established with the correlation between the distance and pH, ORP. The change of pH and ORP can be described by the rate of initial values to experimental values. We demonstrate a realistic possibility of the mathematical approach to assess an environmental impact from disused mines cause the rate range is 0.95 to 1.03 for 60 days. Therefore our proposed approach will be useful as a few promising method for the management of heavy metals in many mines.

국내에 자연 방치된 폐광산에 대한 문제가 대두되면서 폐광산 주변지역에 대한 산성광산폐수와 중금속 광산폐기물의 오염실태조사가 활발히 진행되고 있다. 본 연구는 폐광산의 유출수와 광산폐기물에 주변 오염지하수 내의 중금속 As, Cd, Pb, Fe, Mn, Zn, Cu에 대하여 무기 응집제의 첨가와 pH의 조절에 의한 제거효율을 .실내 배치실험을 통하여 규명하였다. 본 실험을 통하여 황산알루미늄(Al$_2$(SO$_4$)$_3$ㆍ13～14$H_2O$), 염화 제2철(FeCl$_3$ㆍ6$H_2O$), 황산 제2철(Fe$_2$(SO$_4$)$_3$ㆍ n$H_2O$)을 이용하여 오염수내 중금속을 90%이상 제거할 수 있었으며, 폐광산 침출수나 오염 지하수의 중금속 제거에 0.1 wt%의 응집제 첨가만으로 응집제를 이용한 화학적 처리 방법이 효과적으로 사용될 수 있을 것으로 판단되었다.

Abandoned mines represent unused space resulting from resource use and changes in industrial environments. Efforts are underway to repurpose such underground spaces, leveraging their unique attributes of temperature stability, shading, and security. This study aimed to assess the feasibility of operating high-demand data centers and public sports facilities as potential recycling options for abandoned mine spaces. The status of data centers located in abandoned mines abroad was examined, including their operational technology capitalizing on the advantages of underground spaces. Considering the varying sizes of underground spaces in different types of abandoned mine in South Korea, the suitability of installing facilities for 12 different sports was evaluated for potential contributions to the health and welfare of local residents. The utilization of abandoned mine spaces as data centers and public sports facilities is expected to not only recycle industrial heritage but also to allow new development opportunities for local communities.

Plan and management for Ecological Abandoned Mine Lands (AMLs) reuse using Geographic Information System (GIS) technique are an ideal method. GIS technique display, manage and analyze a spatially referenced data, which can be combined in user-defined ways to make plan and decision about AMLs reuse. Local communities are affected by AMLs. In the past, plan and management of AMLs have never been considered for ecological aspects as well as using GIS. However, the rapidly growing GIS technology have proven to be a valuable tool in the process of understanding environment and of making responsible environmental decisions. This paper suggests that making responsible decision and plan using GIS can create a various types of benefits to local communities. This also shows that GIS may play a vital role at the decision/planning process of analysis and exploration of local environmental situation. We are trying to apply to decision support system for AMLs reuse. Moreover, a lot of thematic maps are making using GIS providing a comprehensive data with images. These can be an ideal platform to deliver meaningful outcomes.

This paper provides a comprehensive overview of geochemical approaches for investigating and assessing heavy metal contamination in abandoned mine sites. Major sources of contaminants at the abandoned mine sites are mine water, waste rocks, tailings, and chemicals used in beneficiation and mineral processing. Soil, sediment, surface and ground water, and ecological system can be contaminated by heavy metals, which are transported due to erosion of mine waste piles, discharge of acid mine drainage and processed water, and dispersion of dust from waste rocks and tailings. The abandoned mine sites should be characterized using various methods including chemical analysis, mineralogical analysis, acid generation prediction tests, leaching/extraction tests, and field tests. Potential and practical environmental impacts from the abandoned mines should be assessed based on the site characterization.

The aim of this paper is analyzing the economic outcome of development aid project on closed mine and submitting the policy alternatives to seek for substitute industries which lead independent growth of that area. Despite the aid project deployed from 2001 to 2010, the economic result appears to be fragile. It is obvious that the contents and magnitude of aid projects has its own limitation to build independent economic structure in closed mine area. Conclusively, to overcome the regional restrictions, it is important to establish the aid project scheme to make a strategic and systematic resource distribution under the regional circumstances.

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.
