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:
This research is on mines that struggle to obtain closure from the state departments. The closure process at the footprints of five Tailings Storage Facilities (TSFs) of a South African gold mine was investigated. They are situated in the Germiston, Brakpan, Springs and Nigel suburbs of the East Rand region of Johannesburg. Very limited scientific research has been done in South Africa on the management of mine closure. The most recent performed research was completed at Coal mines and only one was at an underground gold mine. The history of the case studies at a surface gold mine revealed similar problems, as confirmed in previous research, during the interviews with mine management and the review of operational documents. There is a whole array of causes giving rise to the struggle to obtain closure by a mine, that will be subsequently discussed. Major causes are the lack of estimation of closure costs and the lack of a proper Project Life Cycle (PLC) process for closure by mine management. Previous investigations indicated a general shortfall in estimated closure costs, mining operations that are not planned with closure in mind, closure objectives that are not set at all management levels, final land use after mine closure that is not defined properly, residual and latent impacts that are not dealt with, the post-closure period when the final impact will occur that is not defined and a proper risk assessment based on detailed information that is not properly done and communicated. Another cause is that the integrated process of making closure part of the Environmental Management Programme Report (EMPR) process is not followed. The result of not following the correct process is that mines do not obtain closure. Another reason why mines do not obtain closure is because of an underdeveloped mine infrastructure, e.g. tailings facilities, waste rock dumps, shafts and plants that are not constructed in an environmentally friendly way during the operational phases to facilitate closure. Therefore, these structures need to be changed in terms of their topography and growth medium to ensure an improvement in environmental parameters. This will assist in obtaining sustainability and final closure. Significantly more trust fund money than initially estimated during operations needs to be spent to ensure the above change. Specific issues defined from the case studies were the adaptation of the administration of the closure process, the management of risks, especially the differences in opinions, the management of the mine life cycle for closure and involvement of the land owners and Interested and Affected Parties (l&APs). This research was necessary because companies are uncertain and lack the competency to estimate and to correctly spend trust fund money in order to be sure of obtaining closure. This situation threatens the long-term survival of mining-companies by holding assets and profits back until closure is attained. The state departments also have to address the risks and have to rehabilitate the polluted mine sites if companies do not obtain closure. A proper PLC to facilitate closure was compiled from the above-mentioned data. An important fact to bear in mind is that the activities within the life cycle depend on one another. Therefore, when one activity is disregarded or not properly performed, it will influence the outcome of the remaining activities. The methodology of the research was as follows: Categories to evaluate the closure process of the selected case studies were determined from the project life cycle and the management principles of the literature review. Thereafter a questionnaire was developed from these categories. The questionnaire was subsequently used to guide interviews. After the interviews these categories and findings from the questionnaire were combined and summarised into key findings. The key findings of the research were: • The driving force behind obtaining closure must shift from the State Departments to the mining companies. They must realise there is an opportunity during the closure process to make money and to minimise their long-term liability. The mining company must thus drive the closure process to obtain environmental sustainability. • The gold mines do have problems in terms of cost estimation and trust fund expenditure at their TSF footprints during the closure process. The reasons were a mismanagement of the closure process and making use of a limited information system to make decisions. • A proper closure process does exist, but it can be improved to ensure all interested and affected parties have the same expectations from closure. • There are many activities in the closure process flow diagram which were not properly attended to according to the case studies. • A conceptual closure plan and a draft rehabilitation plan with broad objectives, policies and strategies with detailed descriptions were not compiled during the operational phase, because limited scientific monitoring information was gathered to do a proper risk assessment and some l&APs consultation was done mainly with the material and land owners on a one on one basis. From these key findings the following recommendations could be formulated: • Any mining operation should conduct a closure audit at least every second year and before mining activities change. • A searchable record keeping system must be established to keep track of the closure life cycle development. • Detailed conceptual and final closure plans need to capture the data from the audits and record keeping system. • A communication forum with company management and environmental specialists needs to be established.

Abstract:
A lot of mine were left abandoned, unrehabilitated or unclosed prior to the introduction National Environmental management Act 107 of 1998 and most did not have plans for rehabilitation or mine closure. The law requires that no exploration or production operations may commence unless financial provision has been made that is guaranteeing the availability of sufficient fund. planning is a prerequisite in the early development planning phase and must continue throughout the mine life cycle and closure phase. The financial provisions must be maintained for the duration of the life of the mine until closure when the closure certificate is issued. The financial provision is critical in ensuring that environmental liabilities for rehabilitation and closure are addressed. The purpose thereof is to mitigate the negative impacts of mining operations on the environment. This paper will investigate financial provisions system which is currently in use in South Africa from the financial security methods employed, the setting up, determination, quantification as well as general rules applicable thereto. The surveys undertaken in this regard and records held by the DMR will be relied on. When mine operations stop, a closure certificate must be issued to serve as proof that the plans relating to reclamation and closure have been complied with. The effect of a closure certificate exonerates the holder of such right from any residual or latent environmental liabilities. The paper will further look into the reasons and barriers to proper mine closure. The overall SA legislative framework for environmental liability relating to closure and rehabilitation generally conforms with international expectations. This paper examines the principal legislation and in particular the 2015 proposed regulations for securing financial provision for environmental liabilities. The main objectives of the research were to evaluate whether the current financial provision systems are appropriate in guaranteeing mine rehabilitation and closure. Moreover, whether they can realistically alter the legacy inherited from past abandoned or unclosed mines. Lastly, examination of the correlation between closure certificate and financial provision in relation to mine closure. Findings indicate that money set aside as financial provision for environmental liabilities is not being spent by the state. The law is clear which steps mine companies must take for rehabilitation and closure of new and old mine sites including legacy abandoned sites. The law is only as good as its implementation and enforcement. The Success of any financial surety instrument depends on the care, effort put into setting it up, managing it and meticulous calculation. Most will work if they are done properly.

Abstract:
Surface-strip coal mine rehabilitation planning in South Africa and Australia is immature. Rehabilitation risk assessment, despite being advocated by leading practice guidelines and in some instances by legislation, is conducted with minimum requirements often met by rehabilitation professionals. Specialist data is gathered during mine approval and for the environmental impact assessment process. However, the focus of this is toward assessing mining impacts and not for rehabilitation risk assessment. Quantitative, integrated, multi-disciplinary rehabilitation risk assessment is seldom undertaken. This thesis provides a methodology towards the development of a quantitative, integrative, multi-disciplinary rehabilitation risk assessment model. Its purpose being to 'profile' surface-strip coal mine sites, in terms of their rehabilitation risk and potential for rehabilitation failure, from the outset of mine operations, with adjustments possible progressively during mine operations. The methodology was developed by first reviewing techniques suitable for the development of the model, as well as techniques developed by others. Bayesian networks (BN) were found to be the most suited. A R2AIN framework was then provided as a process towards developing several BN risk event models that can amalgamate to form a synthesis rehabilitation risk assessment model. A case study soil compaction BN model was used to demonstrate the framework in South Africa and Australia. The case study showed that it is possible to integrate and quantify rehabilitation risk, and most importantly to segregate risk into discrete contributing multidisciplines for analysis. Risk percentages can be calculated per multi-discipline, per mine phase, per site, to aid site risk ‘profiling’. It is recommended that further risk event BN models be prioritised for development and that a rehabilitation risk assessment model be developed to synthesise these into one model. This will require continuous improvements in the method, to build confidence, including extensive risk event and synthesis BN model evaluation and testing; improved BN input node states and values; and simplification of the conditional probability table construction method. Adaptation to other mining types, development activities and other regions should be investigated, as well as spatial linkages to geographic information systems. This research contribution improves upfront mine rehabilitation planning and decision making, providing improved tools and techniques than what currently exist.

Abstract:
Gold mine waste poses a significant challenge for rehabilitation practitioners and can negatively impact on soil, air, surface water and groundwater quality. This, in turn, can affect the environmental quality of humans and other biota in nearby settlements and surrounding ecosystems. All mines are required to have a plan in place to impede or mitigate these environmental impacts and to ensure that all legislation is complied with to apply for closure. Site closure is the eventual goal of all mine residue complexes, as it is the stage at which a company becomes released from all legal and financial liability. The South African legislation is comprehensive and essentially requires that all latent and residual environmental impacts are addressed and that an end land-use designation is put in place that conforms to the principles of sustainable development. The Chemwes Tailings Storage Facility complex near Stilfontein was monitored to provide a strategic assessment of the state of the rehabilitation, and to provide recommendations for the successful remediation of problem sites. A combination of vegetation sampling, landscape function assessments and substrate chemical analyses were conducted to gain a predictive understanding of rehabilitation progress. The monitoring was conducted over two years across a chronosequence of rehabilitating sites from tailings dam slopes and an adjacent spillage site. An undisturbed grassland and a starter-wall served as reference sites. The data were first analysed independently and then by making use of multivariate data ordinations. This allowed for holistic investigations of the relationships between sites, substrate chemistry, vegetation composition and landscape function. The results showed that the tailings dams had a distinctly different suite of vegetation from the reference sites, but had no statistically significant differences in composition across the rehabilitating chronosequence. There were positive correlations between rehabilitation site age and landscape function indices, suggesting that some aspects of ecosystem development were occurring over time. In some sites, deterioration in the substrate quality as a growth medium was observed with increases in acidity and salinity. This was most likely caused by pyrite oxidation in the tailings and the high concentrations of free salts. The increasing acidity and salinity resulted in vegetation senescence and declines in landscape function. However, those sites that possessed higher landscape function appeared to have the ecosystem processes in place that temporarily suppressed negative chemical changes. Whilst this was encouraging,the rehabilitation chronosequence had not yet proven the self-sustainability that it would require for closure purposes. Further monitoring would be required over time. The sustainability of the rehabilitating chronosequence was brought into question by the high acid-forming potential of the tailings growth medium. Concerns were also raised over the ability of the established vegetation cover to persist under conditions of increasing stress and disturbance. Furthermore, the land-use capabilities of the sites are limited by current rehabilitation procedures and various recommendations were made to rectify this. A more streamlined monitoring framework for the tailings complex was also proposed. The contribution of this work lies in its holistic integration of monitoring techniques and the meaningful analysis of ecosystem function, an aspect largely ignored in minesite rehabilitation.

During the last five years, successful mine closure has become one of Iscor Coal Business primary strategic focus areas. Three Iscor Coalmines are currently in different stages of closure, i.e. North Field, Hlobane and Dumacol and the demand on management time spent on this issue is increasing. The changing legal environment, especially issues concerning rehabilitation and mine closure, demands that every company must take full responsibility for any detrimental effect that their operations may have on the environment. This study concerns itself with establishing a generic procedure for mine closure. The interface with all stakeholders, external and internal, is considered. The primary focus areas are determined and the most important issues within each area are discussed in such a way that operational managers and strategists could use it as base knowledge for future closures. Applying the model to an actual closure process, i.e. the closure of Durnacol Coalmine, tested the validity of the model and it was verified that the process could be used as a base for future reference.

Abstract:
This thesis seeks to investigate the initiatives that address the socio-economic implications of mine closure that have been implemented by three mining companies which are located in Mongolia, Argentina and Canada. It further addresses the perceptions of stakeholders, specifically community members, local government representatives and mining company employees regarding the initiatives that have been implemented by three mining companies. Additionally, the research examines six mining industry-related frameworks/guidelines, and explores the ways in which these documents interpret the socio-economics of mine closure. Finally, this thesis introduces and evaluates the Socio-Economic Mine Closure (SEMC) Framework, which was originally developed as part of this PhD investigation. There are 10 elements in the Framework: Policy, Presence, Participation, Planning, Performance, Promotion, Perseverance, Patience, Passion, and Personality. The SEMC Framework is assessed in multiple ways: a) against the current literature on mine closure; b) through an online survey in which 151 experts were invited to provide feedback on the elements and sub-element constituents of the Framework and c) by its utility in constructing the fieldwork survey and the feedback of survey participants indicating the appropriateness of the framework. The study indicates that it would be relevant, timely and appropriate for the mining industry to introduce, discuss and adopt the proposed SEMC Framework. The case study analyses, all of which employed interviews, group sessions, and distribution of survey material as part of their methodological approaches, reveal that each case has unique characteristics and that all are context-based. The case studies also indicate that all three situations reveal the presence of some common issues. For instance, the results of the study suggest that, in all three cases, communication levels need to be improved and augmented. An important finding of the overall study concerns the element Personality within the SEMC Framework. Although in both the online survey and in the survey distributed to study participants, this element was ranked as one of low importance, through the interviews, group sessions and researcher observations it became clear that the Personality of the company community liaison does play a significant role in maintaining and fostering relationships between mining companies and local stakeholders.

ENGLISH ABSTRACT: Namaqualand has a very unusual diversity of plant life, with many endemic plant species. The fundamental question of this thesis is how this system, damaged by strip-mining activities, can be rehabilitated. The aim was to base the rehabilitation methods on ecological processes. In order to answer this question an overview of the relevant literature was needed in order to identify possible research needs and also to evaluate the work that has been done in the field of strip-mine rehabilitation in arid areas. An understanding of community and ecosystem dynamics would help to establish aims and methods for site-specific rehabilitation. In Namaqualand, South Africa, there is also a need for experimentation to establish which of the many factors is most limiting to long-term ecosystem recovery. It is important to have a good knowledge of the successional processes and disturbance history of the land which needs to be rehabilitated. The vegetation on unmined areas and mined areas of different ages and treatments after mining, were sampled. It was shown that some areas could be expected to show a large degree of recovery in the space of a few years, whilst others would show little or no recovery over a period of decades. It is important to recognise rehabilitation as a gradual process that takes place at different rates in different areas and in different years. The planting of Atriplex nummularia and sowing of Atriplex semibaccata did not facilitate the return of indigenous, perennial species, but rather seem to inhibit their return. In view of the importance of topsoil in terms of the fertility of the soil and the seed bank present in the topsoil, the influence of topsoil removal and stockpiling due to strip-mining activities were tested. The soil fertility was tested by means of radish bioassays and soil laboratory analysis, whilst species diversity and richness were tested with seedling emergence trials. As expected a higher plant species diversity was found on the unmined soils and radishes grew larger on these soils. The topsoil deteriorated in terms of plant species richness, diversity and soil fertility whilst it was stockpiled. Direct replacement of topsoil would ensure a planting medium closer to the pre-disturbance level that could lead to fairly rapid and successful recolonization of the mined area. Successful plant recruitment also depends on the microsites to which seeds are dispersed. The effect that different microsites had on seed germination, seedling growth and survival was tested. It was found that micro catchments always yielded the highest numbers. The establishment and survival of seedlings in the other microsite types (under single shrubs, under clumped shrubs and in the open) varied, depending on the amount of rainfall received in the particular year. Lastly, I experimented with the translocation of three local, indigenous, succulent plant species. These plants were transplanted either in clumps of three together or alone, since I hypothesized that planting them together would facilitate their survival. However, it was found that it depended largely on the morphology of the plant and the amount of rainfall received in a particular year, whether these plants will compete with each other for limiting resources or facilitate each other's survival. The thesis contributes to the understanding of vegetation dynamics in the Succulent Karoo after strip-mining has taken place. Guidelines are provided based on ecological processes, for strip-mine rehabilitation in the Succulent Karoo.
AFRIKAANSE OPSOMMING: Namakwaland is bekend vir sy ongewone diversiteit van plante, met baie endemiese spesies. Die fundamentele vraag wat deur hierdie tesis gevra word is hoe hierdie sisteem, wat beskadig is deur oppervlak mynbou, gerehabiliteer kan word. Die doel is om die rehabilitasie metodes te baseer op ekologiese prosesse. 'n Oorsig van die relevante literatuur was nodig om moontlike areas van verdere navorsing te identifiseer en ook die navorsing wat reeds gedoen is oor rehabilitasie van oppervlak myne in ariede gebiede, te evalueer. 'n Goeie begrip van gemeenskap en ekosisteem dinamika sal help om doelwitte en metodes daar te stel vir die rehabilitasie van spesifieke areas. Dit is ook nodig om in Namakwaland, Suid -Afrika, uit te vind watter van die baie faktore, die lang-termyn herstel van 'n ekosisteem, die meeste verhinder. Dit is baie belangrik om In goeie kennis te hê van die versteurings geskiedenis van die area wat gerehabiliteer moet word, asook die suksessionele prosesse wat werksaam is. Plantegroei van areas wat op verskillende tye gemyn en verskillend behandel is, asook ongemynde areas is ondersoek. Sekere areas het In groot mate van herstel gewys in 'n tydperk van 'n paar jaar, terwyl ander, min of geen hersteloor 'n periode van dekades getoon het nie. Dit is belangrik om rehabilitasie as 'n geleidelike proses te sien, wat teen verskillende tempos plaasvind tydens verskillende jare en in verskillende areas. Daar is bevind dat die plant van Atriplex nummularia asook die saai van Atriplex semibaccata nie die terugkeer van inheemse, meerjarige spesies bevoordeel nie, maar dit eerder inhibeer. Aangesien die bo-grond so belangrik is in terme van die grondvrugbaarheid en ook die saadbank wat teenwoordig is, word die invloed van die verwydering en opberging van die bogrond getoets. Die grondvrugbaarheid was bepaal deur groei-toetse op radyse en laboratorium analise op die grond te doen. Die plant spesie diversiteit en rykheid was bepaal met In saad ontkieming studie. In ooreenstemming met die verwagte uitkoms, was die plant spesie diversiteit hoër op die ongemynde bo-grond en die radyse het groter geword op dieselfde grond. Dit kom voor asof die plant spesie diversiteit en rykheid, asook die grond vrugbaarheid afneem met tyd wat die bo-grond geberg word. Die direkte verspreiding van die bo-grond nadat dit verwyder is, sal In medium vir die plante verseker wat nader is aan die vlak voordat die grond versteur is. Dit sal oak sorg vir redelike vinnige en suksesvolle terugkoms van plante op die gemynde grond. Die suksesvolle vestiging van plante hang ook af van die mikro areas (klein areas in terme van die grootte van 'n saad, wat In eie mikro-klimaat vorm), waarna saad versprei word. Die effek van sulke mikro-gebiede op die ontkieming van saad, die groei van die saailinge en die oorlewing van die saailinge was bepaal. Mikro-water- opvanggebiede het in al drie bogenoemde gevalle die hoogste syfers getoon. Die vestiging en oorlewing van saailinge in die ander mikro-gebiede (die area onder enkel struike, die area onder groepe struike en oop areas) het gevarieer afhangend van die hoeveelheid reënval wat ontvang is in die spesifieke jaar. Laastens, is daar ge-eksperimenteer met die oorplant van drie plaaslike, inheemse, sukkulente spesies. Hierdie plante was alleen geplant of in groepies van drie, bymekaar. Die hipotese was dat huloorlewingskanse beter sal wees as hulle saam geplant word. Dit was egter bevind dat die hoeveelheid reënval in 'n spesifieke jaar en die morfologie van die plant, bepaal of hulle sal kompeteer vir die beperkte bronne en of hulle deur saam te groei huloorlewingskanse sal verhoog. Hierdie tesis dra by tot die verstaan van die plantegroei dinamika in die Sukkulente Karoo nadat oppervlak mynbou plaasgevind het. Riglyne vir die rehabilitasie van oppervlak myne, gebasseer op ekologiese prosesse, word ook voorgestel.

Abstract:
Financial assurance for mine closure has been widely adopted by governments and companies internationally. Concern has grown in and around the global mining and mineral processing industry over potential risks associated with insufficient funding for mine closure. The motivation of this research is to review financial assurance information from several jurisdictions and to quantitatively assess closure cost for a specific example. This research address the following four objectives: 1. To carry out a literature review on financial assurance for mine reclamation. 2. To compare present regulations and policies on financial assurance for mine closure in Canada, United States and Western Australia. 3. To identify expectations for different types of mining. 4. To develop the closure approaches and apply a method to estimate and calculate the closure cost for a mine site. Main research results are as follow: a. Significant reclamation financial assurance information is highlighted, and the expectations of various stakeholder are identified for different types of mines in various jurisdictions across the world. b. Mine reclamation laws in selected jurisdictions of the Canada, United States, Western Australia have some differences and similarities in regulating agency, closure legislation, guidelines and other aspects. Regulations and policies on financial assurance for mine reclamation in the United States and Canada can be classified into prescriptive and performance-based approaches. The performance-based approach is preferred by mining companies for mine reclamation regulations. c. Developing a mine closure cost estimate requires an understanding of the site-specific closure requirements and available software can be used to perform the closure cost estimates. This study applies the Sherpa software to calculate the closure cost of a conceptual gold mine near Winnemucca, Humboldt County, Nevada. ArcGIS Software is used for calculating the size of each small surface water catchment areas for this mine. The final cost estimate for the total closure cost for the gold mine near Winnemucca, Humboldt County, Nevada is $32,417,400 including $22,574,400 direct cost and $9,843,000 of indirect cost. Considering the Gross Receipt Tax of $677,200, the total financial assurance for this project is $33,094,600. The total overhead costs account for 30.4% of the direct project costs.
