Abstract:

The Ranger Project Area, located on the lands of the Mirarr clan, is surrounded by Kakadu National Park. After 40 years of uranium production at Ranger Mine, rehabilitation has begun, with a commitment that the land will be restored to a standard such that it could be incorporated into Kakadu National Park. Historically, mine closure has not been done well in the Northern Territory, and little if any consideration has been given to the views of Aboriginal landowners. An Aboriginal perspective of country recognises the interrelationship, via local kinship and moiety systems, of all things – the rocks, plants, animals, people, stories, weather, ceremonies and tradition. There is an opportunity for this worldview to be incorporated into the rehabilitation of Ranger Mine. The mine’s operator ERA (a subsidiary of Rio Tinto) has agreed to Cultural Closure Criteria that reflect a desire of Bininj (Aboriginal people from the region) to again use the land for hunting and gathering, recreation and cultural practice. Allowing Aboriginal people to have input to rehabilitation planning demonstrates a respect for people’s knowledge and connection to country. At Ranger, where the mine was imposed against the wishes of the traditional owners, this is an important step in a return to stewardship of this land and reconnecting people to place.

Abstract:

Despite closure regulations being recent in Brazil, many mining companies are attempting to adopt best practice and are facing the challenge of closing their mines properly instead of simply complying with current legislation or abandoning the mine site. This paper summarizes mine closure according to both the Brazilian legislation and the "Deliberação Normativa" COPAM Nº 127, that establishes the directives and procedures for environmental assessment at the mine closure stage. Even with the lack of laws and regulations addressing mine closure, the Brazilian mining industry today is at the forefront of environmental impact minimisation techniques. Some case studies in Minas Gerais State, two of them located in the Iron Quadrangle, provide excellent evidence of the industry's rehabilitation expertise. This paper presents an overview of mine closure legislation in Brazil and in the State of Minas Gerais and gives some examples of mine closure programmes in effect. It is intended to highlight the changes on mine closure requirements as well as the best practices on mine closure in the State.

Abstract:

Aiming at deriving good practice recommendations for mine closure, this paper reviews the case of a kaolin mine whose production ceased more than ten years ago, but as yet didn't meet its completion criteria. Document review, interviews and site visits showed that: (i) rework was needed to satisfactorily implement land rehabilitation measures such as contouring, slope stabilization, erosion and sediment control and revegetation; (ii) underground water quality was affected during mine operation, causing the mine to be included in the State contaminated sites register. Despite being a small operation, the closure of this mine illustrates a number of problems faced by mining companies in planning and implementing mine closure measures: (1) lack of clear land rehabilitation objectives; (2) the need to manage liabilities related to contaminated sites; (3) loss of organizational memory. The research found that good practices, generally recommended in guidebooks, were not adopted by the company. The main lesson from this relatively simple case - a small mine situated near a dynamic and expanding urban area - are that decommissioning and closure cannot be a makeshift add-on to mine management; these are not trivial activities and require careful planning and integration with mine planning itself.

Abstract:

This paper presents a tool for managing inoperative mines under the responsibility of the Mine Closure and Projects Management/Ferrous Planning and Development Department - Vale S.A., Brazil. Inoperative mines are defined as mines where mining operations are temporarily suspended and there is no definitive strategy regarding their closure. The main management challenges are to: (i) act in a variety of environments and conditions based on action priorities; (ii) identify the main company's image risks; (iii) plan for maintenance and monitoring; (iv) take care of environmental conditions of the sites and follow up audit recommendations; (v) coordinate the field operations and site rehabilitation; (vi) re-evaluate the rehabilitation performance of the site over time, (vii) support the mine closure team. The tool is based on the consolidation of field information through qualitative and quantitative analyses of the environmental risks and quality of each mine. These analyses support the decision-making process and the prioritisation of action to be taken. The tool provides a performance evaluation of the sites, allowing evaluation over time of the maintenance and rehabilitation actions carried out. The input for the tool consists of primary and secondary data (geotechnical and environmental) collected during fieldwork, which is then processed in spreadsheets. These assign prioritisation values based on two main themes: environmental risk and quality. Each of these themes has specific groups of subjects. The prioritization spreadsheet generates thematic maps that present the classification of the mine areas and the action priorities. The tool output is an action plan that guides management, considering all the structures of each site under its responsibility.

Abstract:

Mass closure of copper-sulphide mining sites both in the Sverdlovsk Region and worldwide resulted in the emergence of environmental challenges. One of such challenges is generation and discharge of acid mine waters. Manmade and natural factors have their impact on chemical composition of mine waters due to activation of sulphides oxidation processes taking place in disturbed rock mass and mines. Concentrations of components in treated mine waters are much higher than MAC (dozens and hundreds of times for iron, copper and zinc). That results in pollution of hydrosphere which goes on for decades and spreads over large distances along rivers. Quite a few reasons cause environmental degradation of hydrosphere in old industrial districts. These are baseline amounts of metals in the hydrosphere, low rates of self-rehabilitation of dead pits, high amounts of acid waters, high amounts of contaminants in mine waters, imperfection of treatment systems. Given the demand of mine waters treatment over decades, improvement of existing treatment systems and implementation of new technologies are required.

Abstract:

Extractive industry has had and has negative effects on environmental factors. Limitation of industrial activities carried out in Jiu Valley, materialized by closure of mining units, brings to actuality the rehabilitation of areas occupied by constructions and surface utilities related to the technological process of underground coal extraction. First stage of surface rehabilitation and greening is the demolition of surface buildings by means of technical implosion / blasting or classic techniques. This stage generates a series of physicochemical pollutants that can have a significant impact on environmental factors. The main objective of the current paper is to identify pollutants and the negative effects they may have on human health as well as to reduce the environmental impact of materials from demolition operations. The paper has the advantage of quantifying waste resulting from demolitions in order to reduce impact on the environment by revalorizing the obtained materials (metal, concrete, wood, brick etc.) thus reducing the quantities of industrial waste to be stored. Thus, it is possible to plan the greening of areas affected by mining activities in the shortest possible time, correlated with the program of territorial systematization, in order to capitalize on new economic opportunities for use of these lands.

Abstract:

Abstract. Rehabilitation of post-mining sites in semi-arid/subtropical environments of eastern Australia have a general objective to establish specific types of native vegetation communities as defined in mine closure plans and in relation to the specific biotic and abiotic requirements of such communities. Critical for the success of rehabilitation is the availability of water and hence the climatic characteristic of this geographical region which is defined by a number of weather-bound factors (e.g. potentially erratic rainfall and periods of drought and flooding). However, specific estimates of climate suitability are seldom incorporated into current mined land rehabilitation design. To address this, our analysis combined various broad-scale climatic parameters (i.e. primarily relating to rainfall) to assess bioregional suitability-susceptibility within the context of plant early-establishment in the objective of informing rehabilitation schemes as to the inherent environmental challenges influencing both short- and long-term ecological development. Following our survey of available climate data, we derived site suitability-susceptibility indexes (that are otherwise currently not available within rehabilitation schemes) and compared the performance of 9 mine site locations in which our Centre has been engaged in environmental monitoring (Weipa, Mt. Isa, Ernest Henry, Eromanga, Kidston, Curragh, Tarong, North Stradbroke Island, and Newnes Plateau). More specifically, the sites were ranked from most-to-least suitable and compared with natural vegetation patterns (as estimated by the mean NDVI). Overall, it was determined that regular rainfall and relatively short periods of water-deficit are key characteristics of climate suitability (as found among the relatively more temperate coastal-hinterland sites), whereas high rainfall variability and (or) prolonged seasonal drought are primary characteristics of unsuitability (as found among the arid central-inland sites). Conceptual and practical considerations are provided which could inform rehabilitation schemes as to the inherent environmental challenges influencing both short- and long-term ecological development.

Abstract:

The potential environmental impacts of mining, increasing environmental legislation and public awareness have received increased attention world-wide in the last two decades. The focus of concern by the industry, environmental regulatory agencies and members of the public is the systematic rehabilitation of ex-mine sites to improve the quality at site for potential future commercial land use. The minerals extracted from these mine/quarry sites are essential in the construction, semiconductor, high-technology, ceramic and other manufacturing sectors for further industrial development. However, efficient engineering design and systematic economic evaluation of mine sites for site rehabilitation are required in maintaining the expected standards of environmental compliance. With escalating production costs and the keen competitiveness of the mining industry world-wide, the necessity to increase the efficiency in site rehabilitation is getting more prominence. A coordinated environmental protection and rehabilitation programme is essential if the environmental awareness of the community and the demands of the respective planning authorities are to be accommodated. There is thus a need to increase the base of knowledge for efficient planning in the systematic and progressive rehabilitation of current and future ex-mine sites. An efficient modeling tool is required for the systematic planning and design of potential economic land development of ex-mine sites. The applicability of Remote Sensing and Geographic Information System (GIS) technology is a useful tool to acquire spatial information for the systematic design and planning of potential development of ex-mine sites. This research was conducted to detect the trends in the suitability of land cover changes via land cover change detection of ex-mine sites and validated with reality. The findings are useful to assist in the development of a tool for efficient modeling and design of potential economic development of ex-mine sites. The aim of this research is to quantify, model and map the economic potential of the ex-mine sites for built up areas such as housing and other urban infrastructures. Land cover classes were interpreted into maps and the accuracy of the maps were validated to reference data and actual ground scenarios. The study for validation of the proposed modeling tool was carried out using the large prominent mining area in Malaysia namely the Kinta District. Results from the validation study carried out indicate that the correlation of the results obtained from this Integrated Remote Sensing and GIS tool for modeling to field data is in the range of 0.87-0.92 which is acceptable and close to reality.

Abstract:

ABSTRACTThe ant species were sampled in one campo (grassy shrubland), one mata (semideciduous rain forest) and 11 rehabilitated bauxite mine plots at Poços de Caldas, in the humid sub-tropical climatic region of Brazil. Rehabilitation was either by planting AustralianEucalyptusspp, the BrazilianMimosa scabrellatree, or by planting mixed mata trees. Sixty-eight ant species were recorded, of which 26 were exclusively found in the native vegetation and 16 were confined to the rehabilitated plots. Ant species richness built up most rapidly in areas rehabilitated with mixed mata species and least rapidly in areas withEucalyptus. Younger rehabilitated plots appeared to be developing a campo-type ant community, although evidence indicates that more mata ant species will colonise once tree canopy closure takes place. Rate of ant return in Australia is positively correlated with the quantity and distribution of rainfall – the rates in the current study concur with those from humid sub-tropical climatic zones within Australia, suggesting that similar constraints to the succession may be operating. If found to be the case, this would have practical implications for planning and evaluating the success of rehabilitation.

Abstract:

The hydrosphere of catchments, which are disturbed by mining, is formed under the influence of not only natural, but also, to a large extent, man-made factors over a long period, sometimes tens or even hundreds of years. After the cessation of production, the return of the mining territory to a state as close to natural as possible is possible, as world experience shows, in exceptional cases, provided that the process of reclamation and revitalization is planned at the design stage of mining. In old industrial areas, the selfhealing processes of the hydrosphere are of great importance, which determine the time during which the territory should be considered as an object of accumulated environmental damage. At present, the total removal of metal compounds by mine waters in the discharge zones at flooded copper-ore mines of the Sverdlovsk region amounts to hundreds (manganese, zinc) and even thousands of tons per year (iron). The duration of self-rehabilitation of the hydrosphere of mining areas at the post-operational stage, i.e. the duration of the period during which the content of the main polluting components (copper, zinc, iron, sulfate ion) is reduced to the maximum permissible or background values, is tens or even hundreds of years. During this time, in order to prevent pollution of the underground and surface hydrosphere, expensive measures are required to implement a system of purification of underground and surface waters of the old industrial territory. The research was carried out on the basis of observations of the chemical composition of water bodies in the territory of the abandoned Levikhinsky mine since the beginning of the 2000s.

Abstract:

Linkage of "Lakes Zwenkau-Cospuden" as one of the elements of land reclamation after the open-cast mines and its future importance for the development of the region The open-cast mine "Böhlen", closed in 1921, in 1969 was transformed into "Zwenkau"("Zw") open-cast mine. In the seventies, together with its smaller neighbouring mine "Cospuden"("Cs"), became one of the greatest enterprises of the Central German lignite mining area. In the last centuries Zw and Cs mines had an significant influence on the economic, technical and scientific progress of this region. Although the mines were in separate mining areas, very close relations of proximity existed between them, particularly in the superposition of the lowering ground water areas. Thus, the total mass of the mine tailings "Cospuden" in the mining sector "Zwenkau" was flattened and designed for land reclamation. Since the cessation of lignite mining in the area Böhlen/Zwenkau/Cospuden the south region from Leipzig has been changed fundamentally. The remaining holes, which mines left behind, became lakes. Along the lakes raised beaches, ports and holiday houses. Lusatia and Central German Mining Administration Company (LMBV), which is now responsible for the reclamation and rehabilitation of disused mines, proposed a new perspective of this region, perceived as a part of nature and human-being. The main emphasis has been placed on the development of created lakes, flow-up phase and good water quality assurance. Some of the new lakes are connected together with artificial canals and locks. This also relates to "Zwenkau-Cospuden Lakes" (LMBV 2009). In this article the methods of management former mining areas in the South from Leipzig, with the great accent put on the linkage of "Lakes Zwenkau-Cospuden", are described. Necessary test on the soil samples from this field are explained. Finally, the influence of the restoration of the area on the development of the region is shown.

Abstract:

Driven by the world’s thirst for energy, the demand for uranium is rapidly increasing. Hence, producers of uranium are struggling to keep up with demands and are exploring more cost-effective methods of extraction. Uranium is currently mined via open pit and underground mining as well as with in situ leaching methods, with in situ leaching currently accounting for approximately 45 % of total uranium production. Studies have shown that the presence of uranium in soils strongly affects the composition and function of resident microbial communities. In view of the close association of biological processes and uranium geochemistry, it is surprising how little information is available on the effect of microbial communities on in situ leaching. Hence, this review focuses on the possibility to exploit the properties of such microorganisms and identify opportunities to use natural microbial processes to improve uranium recovery and mine site rehabilitation.

Abstract:

Abstract Introduction Engineered skin substitutes (ESS) were developed to meet the need for prompt wound closure in patients with large full thickness burns. ESS containing autologous fibroblasts and keratinocytes were shown to provide stable wound closure in burn patients, but are limited by hypopigmentation. DNA damage caused by ultraviolet (UV) radiation is a known risk factor for development of skin cancer. In normal human skin, epidermal melanocytes provide pigmentation, helping to shield skin from UV-induced DNA damage. The current study investigated inclusion of human melanocytes (hM) and their role in the response of ESS to UV light in vivo. Methods Primary cells were isolated from skin of healthy de-identified human donors with IRB approval. Three groups of ESS were prepared with fibroblasts and keratinocytes, +/- hM, and were grafted orthotopically to immunodeficient mice: ESS without hM; ESS with light skin-derived (Caucasian) hM (ESS+hML); and ESS with dark skin-derived (African American) hM (ESS+hMD). After 8 weeks in vivo, grafts were irradiated with 135 mJ/cm2 UV, and mice were euthanized after 2 or 24 hours; non-UV treated mice served as controls. Pigmentation and erythema were measured with a Mexameter. Melanocytes and cyclobutane pyrimidine dimers (CPDs) were quantified by immunostaining with anti-TYRP1 and anti-CPD antibodies, respectively, followed by image analysis (Nikon Elements). Statistical analyses (SigmaPlot) utilized t-test or one-way ANOVA; P< 0.05 was considered significant. Results At 8 weeks post-grafting, mean hM density in ESS+hML and ESS+hMD was not significantly different from normal human skin samples. Pigmentation (in Mexameter units) before UV irradiation was significantly different among groups (ESS+hMD > ESS+hML > ESS no hM). UV irradiation did not increase erythema in any group, but resulted in significantly increased pigmentation in ESS+hML and ESS+hMD at 2 hours, but not 24 hours, post-UV. CPDs, the most prevalent form of UV-induced DNA damage, were significantly elevated 24 hours post-UV in ESS without hM. DNA damage was significantly lower 24 hours post-UV in ESS+hML and ESS+hMD compared with ESS without hM. No differences in DNA damage were observed between ESS+hML and ESS+hMD. Conclusions Pigmentation of ESS+hML and ESS+hMD in vivo varied according to the skin phototype of the hM donor, with no difference in melanocyte density, which was similar to normal human skin. Inclusion of either light or dark hM decreased UV-induced DNA damage, suggesting that hM in ESS play a photoprotective role, as in normal human skin. Applicability of Research to Practice Protection against UV-induced DNA damage may reduce the risk of skin cancer in patients grafted with ESS containing melanocytes.

Abstract Introduction In large skin injuries, lack of matrix deposition impedes timely healing process. The longer a wound remains open, the greater is the risk of infection, non-healing, and other complications. It is therefore crucial to find effective means to promote rapid closure of skin defects. Our group has previously developed a liquid in situ-forming nutritional scaffold, known as MeshFill (MF). MF has been previously proven to be very effective in accelerating the wound repair process, notably that of complex wounds. However, MF is limited in its application to deep and tunnelling wounds, and requires reconstitution with a solvent as well as maintenance at cold temperature until application. To address these limitations, our group has developed a powdered form of MF for rapid topical application on superficial skin injuries such as dehisced surgical wounds and burn injuries. Methods Our goal was to investigate whether a powdered form of MF could be directly applied onto the wounds to accelerate healing. Ideally, powdered MF would absorb the moisture within the wound environment and reconstitute into the gel form in situ. We examined the efficacy of powder MF (PMF) compared to reconstituted gel MF (GMF) and to a standard dressing protocol. To do so, splinted full thickness wounds were generated on the back of mice and treated with either PMF or GMF or were bandaged with no treatment (NT). The healing process was monitored until wounds were fully closed. Clinical wound measurements and histological assessments were performed to compare different treatment regimens. Results Application of both PMF and GMF accelerated wound epithelialization at days 7 and 14, compared to NT, and had faster wound closure times. On average, the PMF treatments healed 17% faster than the NT control, and the GMF treatments healed 21% faster than the NT control. No significant difference between PMF and GMF was found for any outcomes. Additionally, our results suggest that epidermis formation was more effective in P and MF conditions compared to NT. Conclusions These findings suggest that topical application of a powdered form of MeshFill is as effective as standard reconstituted MeshFill gel in accelerating the healing process of skin injuries. Applicability of Research to Practice Topical application of a powdered scaffold may be a very convenient and practical method for rapid treatment of large superficial wounds such as dehisced surgical wounds, burn injuries, and filling gaps in meshed skin grafts.

Abstract:

Abstract Engineered skin substitutes (ESS) containing autologous fibroblasts and keratinocytes provide stable wound closure in patients with large, full-thickness burns, but are limited by hypopigmentation due to absence of added melanocytes. DNA damage caused by ultraviolet radiation (UV) increases risk for skin cancer development. In human skin, melanocytes provide pigmentation that protects skin from UV-induced DNA damage. This study investigated whether inclusion of human melanocytes (hM) affects the response of ESS to UV in vivo. Specifically, pigmentation and formation of cyclobutane pyrimidine dimers (CPDs), the most prevalent UV-induced DNA photoproduct, were analyzed. Three groups of ESS were prepared with fibroblasts and keratinocytes, ± melanocytes, and grafted orthotopically to immunodeficient mice: ESS without melanocytes (ESS-hM), ESS with light skin-derived (Caucasian) melanocytes (ESS+hM-L), and ESS with dark skin-derived (African-American) melanocytes (ESS+hM-D). Pigmentation of ESS+hM-L and ESS+hM-D increased significantly after grafting; pigmentation levels were significantly different among groups. Mean melanocyte densities in ESS+hM-L and ESS+hM-D were similar to each other and to densities in normal human skin. After 8 weeks in vivo, grafts were irradiated with 135 mJ/cm2 UV; non-UV-treated mice served as controls. UV modestly increased pigmentation in the ESS+hM groups. UV significantly increased CPD levels in ESS-hM, and levels in ESS-hM were significantly greater than in ESS+hM-L or ESS+hM-D. The results demonstrate that light or dark melanocytes in ESS decreased UV-induced DNA damage. Therefore, melanocytes in ESS play a photoprotective role. Protection against UV-induced DNA damage is expected to reduce skin cancer risk in patients grafted with ESS containing autologous melanocytes.

Abstract:

The share of eye injuries in Russia is from 3 to 8% of the total number of injuries in peacetime. Eye trauma is one of the three main causes of vision disability and accounts for 22.8%. In wartime, the mass admission of wounded with damage to the organ of vision requires prompt decisions on their sorting, treatment, rehabilitation, dismissal, or return to duty. In peacetime, mechanical trauma to the eye is associated with the disability of the working population and large material costs. Considering the relevance of mechanical trauma to the eye, ophthalmologists around the world are constantly investigating the features of the pathogenetic mechanism, diagnosis, and treatment. Retrospective studies are based on the analysis of clinical cases, which are not always homogeneous. Experimental damage modeling has a long history. Attempts to simulate mechanical eye trauma have been made since the 40s of the XX century. Mathematical models are calculated based on known data: thickness, density, the elasticity of tissues, this makes it possible to predict the result of exposure to a wounding agent. Unfortunately, in these models, it is difficult to reproduce the entire complex of pathomorphological changes. The created models fulfilled the assigned tasks but had certain drawbacks. In each subsequent experiment, the reproducibility improved and the model approached the desired one as accurately as possible. Specialists of the Professor V.V. Volkov Ophthalmology Department S.M. Kirov Military Medical Academy since the 40s. are engaged in solving this problem. For the first time in an experiment, B.L. Pole proved that closure of eyeball wounds with corneal and scleral sutures has an advantage over conjunctival covering. B.V. Monakhov et al. created an installation for inflicting mine-explosive injury to the eye. In the experiment, M.M. Shishkin inflicted a combined eye injury by striking the sclera with a knife with a rectangular blade and firing an air rifle at the knife handle. B.A. Kanevsky et al. reproduced a D-type gunshot open eye injury shot from an air rifle with a multi-compression piston pump. The creation of models that reproduce the mechanical trauma of the eye made it possible to study it in an experiment, which improved the quality of diagnostics and reduced the proportion of disability in this pathology (bibliography: 24 refs).

Abstract:

Operating life of a mine lasts from a few years to several decades. Mine closure occurs once the mineral resource is exhausted, or operations are no longer profitable. Mine closure plans are required by most regulatory agencies worldwide before a mining closure permission is granted, and must demonstrate that the site will not pose a threat to the environment and health of the society in future. The article describes a new tool, the brownfields methodology, which can help to promote the revitalization of old mining areas as a part of their technological modernization and subsoil full extraction with environmental damage reduction.

Abstract:

Pit lakes can represent significant liabilities at mine closure. However, depending upon certain characteristics of which water quality is key, pit lakes often also present opportunities to provide significant regional benefit and address residual closure risks of both their own and overall project closure and even offset the environmental costs of mining by creating new end uses. These opportunities are widely dependent on water quality, slope stability, and safety issues. Unfortunately, many pit lakes have continued to be abandoned without repurposing for an end use. We reviewed published pit lake repurposing case studies of abandoned mine pit lakes. Beneficial end use type and outcome varied depending upon climate and commodity, but equally important were social and political dynamics that manifest as mining company commitments or regulatory requirements. Many end uses have been realized: passive and active recreation, nature conservation, fishery and aquaculture, drinking and industrial water storage, greenhouse carbon fixation, flood protection and waterway remediation, disposal of mine and other waste, mine water treatment and containment, and education and research. Common attributes and reasons that led to successful repurposing of abandoned pit lakes as beneficial end uses are discussed. Recommendations are given for all stages of mine closure planning to prevent pit lake abandonment and to achieve successful pit lake closure with beneficial end uses.

Abstract:

Mining companies are responsible for the impacts that result from their mining activities even after the mining period has ended. At the same time, at the European and international levels, there is a lack of a detailed operational methodology comprising environmental risks during and after closure of underground coal mines. The environmental risk aspects that need to be considered when planning the closure of an underground coal mine and post closure in the broader environmental context are the following: modification of water flow scheme, surface instability, mine gas emission on the surface, and water and soil pollution. In this study, we focus on assessing groundwater risk in the context of an underground coal mine closure and evaluating the selected risk mitigation strategies in terms of performance and cost. The results from this study could be used for developing a final closure groundwater assessment plan by selecting the most feasible treatment alternatives for different environmental impacts, together with the transitional monitoring that could guarantee a hazard level in compliance with land reuse and the use of natural resources. Finally, the cost-efficient monitoring and treatment programs are used to estimate the financial provisions needed to mitigate groundwater risks during underground coal mine closure contexts.
