Abstract:

The new caving megaprojects that are planned to go into production in the next decade have scheduled horizontal developments at very high rates, which are difficult to achieve. Research has been conducted that seeks to model the construction times for underground developments to determine the feasibility of achieving the planned rates. However, these previous attempts do not consider all the operational aspects that make up the mine development cycle. Here, we present a discrete event simulation (DES) model that individualizes each unit operation of the development cycle to determine the construction rates that new projects will be able to attain. The developed model was applied to the New Mine Level (NML) of the El Teniente Division (DET). The results indicate that it would be impractical to achieve the advance rates scheduled in the original plans if the unit operations of the mine continue to be executed using the status quo. The metres developed after six years in the sections analysed can be significantly improved by changing the maintenance strategy for the equipment (457 metres increase), orepass availability (194 metres increase), and the initial planning sequence (1 598 metres increase). It is recommended that the mine implements a flexible maintenance strategy, defines a strategy to ensure and increase orepass availability to contractors, and makes use of current simulation tools for a more robust development sequence planning.

Abstract:

Ventilation is an attempt to drain clean air into the mine and remove dirty air out of the mine. The main components of a mine ventilation system are intake, working, and exhaust. Intake is a tunnel and wells system where air flows from the surface into the mine. The purpose of the ventilation system in an underground mine is to provide and drain clean air into the mine for breathing and comfort of mine workers. Based on the Ventilation Design Criteria used by PTFI, the minimum airflow level required for every mine worker is 0.033 m3 / s / worker. Based on PTFI Ventilation Design Criteria, the minimum level in diluting smoke of heavy equipment diesel engine is 5 m3 / min or 0.08 m3 / s / kW. PT Freeport Indonesia is currently developing new underground mines namely Grasberg Block Caving (GBC) and Deep Mill Level Zone (DMLZ) which will be mined using the block caving method.

Abstract:

Planning a modern open pit mine requires a computer model of the resources and reserves to be mined, both block and grid models. With current technological developments and has entered almost all sectors including the mining sector, as for computer program packages (software) used by the mining industry, namely Microsoft excel, Mincom minescap and others. An evaluation and analysis system of mine plans/ mine schedules is necessary to make predictions of mining operations that will be carried out and can be used to find the cause of deviation or design deviations. There are several weaknesses in making scheduling manually, so scheduling is done using SPRY which is very helpful in the scheduling process.

Abstract:

In this study, geographic information system (GIS)-based methods and applications utilized for mine development were reviewed. Three types of GIS-based studies, namely studies on mine planning, operation, and environmental management, were examined to describe the role of GIS as a decision-making support tool in mine development. This review was conducted by classifying previous GIS-based studies into several subtopics that pertain to mine development activities and the range of environments to be managed. Because the use of GIS is appropriate for spatial data management related to ore deposits and mine environment conditions at various scales, the applications of GIS-based methods in mine development could be expanded further.

Abstract:

Creation of mine development plans for mining operations in the ferrous and non-ferrous metals industry is a timeconsuming and creative process that requires high levels of specialist expertise, especially in manual planning, where it is quite difficult to assess the impact of decisions made hic et nunc on the future development of the company. Application of mining and geological systems in planning makes it possible to simulate and assess many different options in mine development within a short period time and with sufficiently high reliability. These systems allow planning specialists to make more informed and correct decisions without the fear that these decisions may lead to deterioration of open pits or mines. The article describes the course of project implementation to transform the business processes of mine planning using mining and geological information system by Dassault Systemes at the METALLOINVEST Group of Companies as exemplified by the Mikhailovsky GOK Lebedinsky GOK mines.

Abstract:

Geophysical techniques have been applied to petroleum exploration since early in the 20th Century. More recently geophysical methods have been applied in detail to mineral and coal exploration. As a generalisation, geophysical techniques have not been applied in the areas of mine planning, development and production.A variety of geophysical methods have been improved or adapted within BHP to provide accurate, cost effective services to the mine manager on time scales that are realistic for day to day planning and production. Considerable success has been achieved with in-seam seismic, cross-hole seismic and surface seismic techniques. Electrical and magnetic methods have also been beneficial for specific applications.The identification and evaluation of mineral deposits increasingly uses a range of advanced geophysical techniques. Geophysical techniques are now also emerging as key factors in mine planning and production. The purpose of this paper is to show how BHP is developing a variety of geophysical techniques to improve the eSfficiency of exploration, mine planning and production both for minerals and coal. Emphasis is placed on the benefits of these advanced geophysical techniques on day-to-day mine operations. This, of course is only one company's perspective viewpoint, but since BHP has such a wide diversity of operations, this viewpoint may have general applicability.BHP has had a long history of using geo-expertise in a wide range of operations over the past 40 years. This expertise developed in the minerals and coal industries but has subsequently developed into the petroleum industry. In regard to the coal industry alone, several notable geophysics firsts can be attributed to the coal geology groups within BHP. These firsts include: The application of surface seismics to coal exploration; Geophysical logging ? BHP were instrumental in bringing BPB Instruments Ltd to Australia; Radar ? early experiments were undertaken at Cook Colliery; Development and application of high resolution surface seismics in Queensland and New South Wales; Development and routine application of in-seam seismics; Cross-hole seismic/in-seam seismic tomography ? application of a production oriented package to coal and metalliferous mines.In the development of these techniques for the mining industry, a number of common factors are present which have resulted in them being commercially successful. BHP's background as a large resources company has obviously provided the initial impetus to develop smarter geophysical techniques, but this is only one factor which has made them successful. The old adage of a new product or technique being 1% inspiration and 99% perspiration also applies to the development of these techniques.Probably the most important single factor to consider for the successful development of innovative geophysical techniques is that they require a multi-stage team effort over at least two years, (typically 4-5 years for the more complex developments) and that failures can be expected throughout this period. Also the expectations of production personnel are often too great during this developmental stage, which leads to a perception that the technique in question is not useful even after all the 'bugs' in the system have been removed. The onus is on researchers to clearly outline both the potential benefits and possible failures of a new technique during its developmental stage, so that it will subsequently be more readily accepted in the mining production environment.

Abstract:

Editor’s note: The Geology and Mining series, edited by Dan Wood and Jeffrey Hedenquist, is designed to introduce early-career professionals and students to a variety of topics in mineral exploration, development, and mining, in order to provide insight into the many ways in which geoscientists contribute to the mineral industry. Abstract Mine planning is the process that determines the way in which an ore deposit will be mined over the life of a mining operation. It necessarily draws on everything that planning engineers believe will determine the ultimate success of the proposed mine and uses as its foundation all of the geology-related data on the deposit. It is both a strategic and a tactical process that first considers a longer-term horizon based on strategic considerations, followed by more detailed shorter-term planning processes, in this order; the latter are the result of tactical considerations. This structured process may also be referred to as integrated mine planning, and it is driven by a broader corporate strategy or set of objectives. As such, it is much more than the mining engineering section of the mine development process. It has to include inputs from all related disciplines, by combining all of the measured properties of the deposit with mining-associated parameters. This results in the planning process incorporating a significant number of interrelated parameters. If these parameters are not used diligently and accurately or are not well aligned, or if the underlying data are deficient in either quantity or quality, the project or operation is unlikely to achieve its potential, by virtue of failures in the planning process. Best-practice integrated planning incorporates relevant inputs from all mining-related fields: geology, geotechnical, geochemical, hydrogeological, hydrology, mining operations, minerals processing, marketing of product, waste management, tailings, environmental, social science, mine closure, etc. It includes all interfaces in the business-value driver model, from exploration drill holes to the mine closure plan. The planning process cannot be completed successfully by mining engineers working in isolation from professionals in other key disciplines. Because geology provides the foundation on which the mine plan is built, the quality and accuracy of the geologic data provided to planning teams by exploration geoscientists is crucial.

Abstract:

Airborne hyperspectral imagery recorded by the NASA’s Next Generation Advanced Visible/Infrared Imaging Spectrometer (AVIRIS-NG) was analyzed for environmental mapping of the Rio Tinto mining district in southwestern Spain. The Rio Tinto mining district contains a giant world-class polymetallic sulfide deposit that has been mined from the antiquity to the modern times. The mining and ore processing activities have created large areas covered by sulfide-bearing mine waste, tailings, flooded open pits, slags, galleries and other mining facilities. The sulfide-bearing mine waste generates acid mine drainage (AMD) that contaminates the fluvial network. The Rio Tinto River is one of most AMD contaminated rivers in the world. Many secondary minerals associated with sulfide-bearing mine waste have diagnostic reflectance spectra due to absorptions of ferric and ferrous iron, water and hydroxyl. The mapping of the surface distribution of these secondary minerals is useful for environmental studies. The AVIRIS-NG radiance data were converted to surface reflectance using the Fast Line-of-sight Atmospheric Analysis of Hypercubes model. The AVIRIS-NG imagery was analyzed using the spectral mixture analysis. The AVIRIS-NG accurately mapped acid water, jarosite, goethite, hematite, melanterite, rozenite, copiapite, gypsum, undifferentiated metal sulfate hydrates, sericite and kaolinite. Acid waters occur in the tailings ponds, in the Rio Tinto River, and in various other locations within the study area. Jarosite, goethite and hematite are the predominant secondary iron minerals in the areas covered by sulfide-bearing mine waste. These secondary iron minerals are indicators of acid mine drainage generation. In few locations were distinguished from the AVIRIS-NG data the mineral melanterite and its dehydration product rozenite. The study gives new information on the surface distribution of environmentally important secondary iron minerals in the Rio Tinto mining district in southwestern Spain. The mapping results produced by the analysis of the AVIRIS-NG data can be useful to the environmental studies concerned with the pollution from acid mine drainage of the fluvial network of the area.Uso de imagens AVIRIS-NG da NASA para mapeamento ambiental no distrito de mineração de Rio Tinto, sudoeste da EspanhaResumoAs imagens hiperespectrais aerotransportadas registradas pelo espectrômetro avançado de imagens visíveis/infravermelhas da NASA (AVIRIS-NG) foram analisadas para o mapeamento ambiental do distrito de mineração de Rio Tinto, no sudoeste da Espanha. O distrito de mineração de Rio Tinto contém um gigantesco depósito de sulfeto polimetálico de classe mundial que foi extraído desde a antiguidade até os tempos modernos. As atividades de mineração e processamento de minério criaram grandes áreas cobertas por resíduos de mineração contendo sulfeto, rejeitos, minas a céu aberto inundadas, escórias, galerias e outras instalações de mineração. Os rejeitos de mineração contendo sulfetos geram drenagem ácida de mina (DAM) que contamina a rede fluvial. O rio Rio Tinto é um dos rios mais contaminados pela AMD no mundo. Muitos minerais secundários associados com rejeitos de mina contendo sulfetos têm espectros de refletância diagnósticos devido a absorções de ferro férrico e ferroso, água e hidroxila. O mapeamento da distribuição superficial desses minerais secundários é útil para estudos ambientais. Os dados de radiância do AVIRIS-NG foram convertidos em refletância de superfície usando o modelo de Análise Atmosférica de Linha de Visão Rápida de Hipercubos. As imagens do AVIRIS-NG foram analisadas usando a análise de mistura espectral. O AVIRIS-NG mapeou com precisão água ácida, jarosita, goethita, hematita, melanterita, rozenita, copiapita, gesso, hidratos de sulfato de metal indiferenciado, sericita e caulinita. Águas ácidas ocorrem nas lagoas de rejeitos, no rio Rio Tinto e em vários outros locais dentro da área de estudo. Jarosita, goetita e hematita são os minerais de ferro secundários predominantes nas áreas cobertas por rejeitos de mineração contendo sulfetos. Esses minerais de ferro secundários são indicadores de geração de drenagem ácida de mina. Em poucos locais foram distinguidos dos dados do AVIRIS-NG o mineral melanterita e seu produto de desidratação rozenita. O estudo fornece novas informações sobre a distribuição superficial de minerais de ferro secundário de importância ambiental no distrito de mineração de Rio Tinto, no sudoeste da Espanha. Os resultados do mapeamento produzidos pela análise dos dados do AVIRIS-NG podem ser úteis para os estudos ambientais relacionados com a poluição por drenagem ácida de mina da rede fluvial da área

Abstract:

The difficulty of effectively planning and assigning weekly activities has a significant influence on the long-term productivity of an underground mine. It is an especially difficult task to choose the best places for operations inside an underground gold mine. It cannot be resolved by only selecting the levels with the highest grade of ore because the underground mine’s ore transport network has a range of capacity limitations that may prohibit the immediate mining of all the levels with the highest grade. To solve this scheduling difficulty, we formulated a new mixed-integer network flow model of the problem of weekly allocating mining operations in an underground gold mine such that the total gold mined (in ounces) was maximized subject to the transportation capacity constraints. The model was applied to an underground gold mine in Red Lake, Ontario, Canada. The results were compared to those of two greedy heuristic models that were designed to represent the decision-making heuristics that are currently used at the mine. It was found that the new model yielded solutions that improved upon the two greedy heuristics by 14.7% and 6.0%, respectively. The results of this research illustrate that the development of this optimization model can support decisions to improve a gold mine’s productivity.

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:

In recent years, Indonesia has become the largest coal exporter in the world, and most of the coal is being mined by means of open-pit mining. The closure of an open-pit mine will usually leave a pit morphological landform that, in most cases, will be developed into a pit lake. One of the main issues in developing a pit lake is the understanding of the pit lake filling process. This paper discusses the hydrological model in filling the mineout void in a coal mine in Kalimantan which is located close to the equatorial line. The J-void is a mineout coal pit that is 3000 m long and 1000 m wide, with a maximum depth of 145 m. The development of the J-void pit lake after the last load of coal had been mined out experienced a dynamic process, such as backfilling activities with an overburden as well as pumping mine water from the surrounding pits. There are two components in the model, i.e., overland/subsurface and pit area. The overland zone is simulated using the Rainfall-Runoff NRECA Hydrological Model approach to determine the runoff and groundwater components, whereas the pit area is affected by direct rainfall and evaporation. The model is validated with the observation data. The main source of water in the J-void pit lake is rainwater, both from the surrounding catchment area as well as direct rainfall. As this coal mine area is characterized as a multi-pit area and, consequently, several pit lakes will be formed in the future, the result of the hydrological model is very useful in planning the future pit lakes.

Abstract:

In the coal phase-out era, achieving sustainable mine closure is significant and prioritizes targets for the mining industry. In this study, the already closed lignite mine of Kardia, North Greece, is investigated, where the mine void left is naturally filled with water. The viability of different repurposing land uses is evaluated, and the natural water level development inside the mine pit is investigated concerning its future uses. The potential for solar photovoltaic (PV) panels developed on mining land and its surrounding area is evaluated in combination with the application of pumped hydro storage (PHS) technology, utilizing pit lake water. Except for electricity system planning, other end-uses that offer multiple, mutually reinforcing and lasting benefits are investigated, such as recreation parks, terrestrial wildlife, aquaculture and agriculture. All repurposing scenarios are evaluated with regard to the spatiotemporal evolution of the lake, by generating forecasts of the dependent variables (rainfall and temperature) via linear (autoregressive integrated moving average) and non-linear (artificial neural network) models. The prediction of pit lake natural development redefines the new land use layout and the land repurposing decisions. This is essential for strategic planning, considering the Greek lignite mining industry’s priority regarding transitioning from the current coal-based electricity to renewable energy sources (RES) technology.

During the exploitation period, mine produced 40 million tons of lignite. By extracting the coal reserves, mine was shut down in 1991. Underground caves were filled by classical methods present in underground mining and all entries are sealed. The ground infrastructure remained preserved and has had usable values in three periods when infrastructure was used for various purposes. Conversion for re- use of mining infrastructure is not defined by any categorisation for infrastructure conversion use as the planning element of sustainable development for active or shutdown mines. The article defines categories of sustainable development based on utilizing mine infrastructure on the sample of “Lipnica” mine. The universality of categorisation points out the possible options of optimal re-use of coal mine infrastructure, indicating implementation of a mining company sustainable development concept, either in government or private ownership. Keywords: categorisation, sustainable development, business incubator, Lipnica mine

Abstract:

As with other engineering design tasks, mine design involves setting design objectives and constraints (the feasible solution space) and finding the optimal design alternative. Mine engineers often struggle to incorporate the preferences of local community members into their evaluation of mine design alternatives because the mining literature lacks tools to quantify such risks during mine planning. This paper presents an approach to evaluate community acceptance (i.e., community preferences for the alternatives) using discrete choice models and decision-based design during mine planning. Using discrete choice models and a rigorous framework, engineers can estimate the cost of social risks as a function of the probability that individuals in the host community will prefer a particular design alternative. They can then estimate the overall utility of a particular design alternative to the project proponents. This paper illustrates the proposed approach with a strategic mine planning exercise for a gold mine. The framework can be a useful tool for designing mines for sustainability, if combined with effective community engagement and management’s commitment to creating shared value.

Abstract:

Open pit mine design and production scheduling deals with the quest for most profitable mining sequence over the life of a mine. The dynamics of mining ore and waste, and spatial grade uncertainty make predictions of the optimal mining sequence a challenging task. Valuation and related decision-making in surface mining require the assessment and management of orebody risk in the generation of a pit design and long term production scheduling. As the most profitable mining sequence over de life of a mine determines both economic outcome of a project and the technical plan to be followed from mine development to mine closure, the adverse effects of orebody risk on performance is critical and are documented in various studies. Ignoring such a consequential source of risk and uncertainty may lead to unrealistic production plans. This paper presented a set of procedures that enable mine planning engineers to carry out a series of analysis, which can be used to evaluate the sensitivity of incremental pit shells and pit designs to grade uncertainty. The results obtained from the analysis have shown to provide valuable information, which can be used to develop mining strategies that are risk resilient in relation to grade uncertainty. A real life application at Sossego copper mine ensure that such procedures are technically implementable, supporting decision-making as (a) in-fill drilling programs; (b) review of mining sequence; (c) identification of areas of upside potential and downside risk and (d) ore blending between mining areas in order to minimize the impact of high risk areas. The goal of this work is to provide an approach for clear risk analysis and management in mine planning cycle to various aspects of pit optimisation and design, resulting in more technically and economically sustainable life-of-mine production plans and mineral reserve depletion.

Abstract:

Coal mine gob, mined-out areas in underground coal mines, often accumulates explosive methane-air mixtures that pose a deadly hazard to miners. A good understanding of the flow field in a sealed coal mine area is crucial in preventing and minimizing accidents associated with mine combustible gases and also for planning and implementing a mine rescue strategy. In recent years, the research on the flow field in the gob has changed from qualitative research in the past to quantitative research. This paper synthesizes the research results of flow field in gob in recent 40 years, covering the permeability of quarried areas, the airflow simulation in quarried areas, and the influence of ventilation parameters and geohydrological conditions on the flow field. Firstly, the overburden failure mechanism and fracture development characteristics of the mine gob, the distribution of porosity and permeability in the gob, and the relationship between them are introduced. Secondly, the development of research methods and numerical models used to study the flow field in mine gob is discussed. The distribution of the flow field in the gob under different conditions is expounded. Thirdly, the research on the prevention and control of fire and explosion risks in the gob is discussed. Finally, the problems to be solved in such research direction are addressed and suggestions are put forward.

Abstract:

In the complex underground environment, the paths planned for coal mine patrol robot are often too long and unsmooth under the influence of low visibility and poor road conditions. To solve the problems, this paper improves the hybrid algorithm between the improved artificial fish swarm algorithm (AFSA) and the dynamic window algorithm (DWA) for global path planning of coal mine patrol robot and introduces the improved genetic algorithm (GA) to enhance the path planning accuracy. Based on the global optimal path, the improved DWA was adopted to design a new adaptive trajectory evaluation function, which improves the ability of the patrol robot to avoid local obstacles. The proposed optimization algorithm was proved feasible through simulations. In addition, a simulation platform for the control of coal mine patrol robot was established, using the software development platform for coal mine patrol robot and robot operating system (ROS). The simulation results show that the improvement shortened the path length by 0.12 m, reduced the time by 3.14 s, and removed many turning points and redundant points. Therefore, the proposed improved hybrid path planning algorithm is effective and superior.

Abstract:

s: Cambodia is a developing country, and mining sector is just started within the last 10 years. Many mining companies have started to explore and carry out the feasibility study amid the scarcity of geological data and technical code of practices. Therefore, the quarry sector is also considered at the early stage in Cambodia, and it is required a standard quarry planning practice. This paper will present the main concepts of (1) quarry operation, development, and design by using the commercial program Minesight to accommodate the mine planning and scheduling. as the result, 25 million ton of limestone was calculated to be a reserve with production of 1 million ton per year; (2) financial model, consisted of cash flow analysis, net present values (NPV), and the Internal Rate of Return (IRR) are the main point for economics consideration. In this point, 47% of internal rate of return was calculated with the net present values of 21.5 million US Dollar and (3) the environmental impact which involves dust, noise, vibration impacts and mine rehabilitation, will be addressed base on the specific local conditions.

Abstract:

This paper studies the rock mass stress state under highland conditions, depending on the geological structure of a particular rock mass area, the tectonic field of stresses and the region relief. This study is aimed to develop an experimental method for assessing and monitoring the properties and state of the rock mass adjacent to mine workings. Experimental studies are performed through stresses measurements in-situ. Based on research results, it has been revealed that the geological structures, tectonic fields of stresses and the earth’s surface relief of the deposit normally reflect the values and direction of the main stresses acting in the mass. These patterns can be used to predict and assess the stress state of the rock mass. During the mass stress state assessment, quantitative dependences have been obtained for determining the stress tensors conditioned by the overlying rocks weight, tectonics and fracturing, and the deposit surface relief The research results make possible to assess the nature of the stresses distribution, to identify the areas of reduced, equal, increased and maximum stresses concentration of the virgin mass, as well as to increase the efficiency of the geoacoustic control developed by the authors for the state of the mass adjacent to mine working. According to the new patterns and dependences obtained, the values and directions have been scientifically determined of the main stresses action, as well as the zones of stresses manifestation. These patterns and dependences are valuable for designing and planning the development of mining operations.

Two dimensional seismic surveying is commonly used in the coal mining industry to assist the mining and development of coal deposits by seismically imaging coal seams. A specialised three dimensional seismic surveying technique has recently been performed over coal mining leases in South Australia and New South Wales, to trial its applicability to coal mine planning and extraction operations.The first two case histories of its trial in Australia are presented, and the conclusion drawn that the specialised three dimensional technique developed to date offers the ability to image coal seams in three dimensions and thereby improve mine planning in regions of complex faulting.

Abstract:

Noise emissions are a significant environmental impact caused by the mining industry in all technological phases of surface mining, mineral processing, and waste disposal. This paper presents the role of noise impact assessment and control in large-scale surface mining operations. Mine planning develops the model of mining operations, ore excavation, and waste dumping scheduling and processing rates, including spatial distribution of mining activities. Such a level of mine planning requires an environmental impact assessment study. This can be achieved by applying noise impact assessment models. The described approach can be used to verify the effectiveness of the proposed protection measures to reduce or eliminate the identified negative impacts. This paper presents a case study of environmental noise impact assessment and control at the Serbia Zijin Copper DOO Bor mine, encompassing the analysis of the noise protection measures efficiency within the planning of large-scale mining operations at the open-pit mine Veliki Krivelj.

Abstract:

PT Timah (Persero) Tbk is a company engaged in mining especially tin. Tin is one of the most important deposits in the development of world technology. PT Timah (Persero) Tbk has an important role in the procurement of tin in the world. In mining, the mine planning stage is very important before the exploitation stage. At the planning stage of a mine will be planned in such a way as to obtain optimal results. One of the stages of mine planning is the planning of the required load equipment and haul equipment. PT Timah (Persero) Tbk plans to open a mine with open pit system that is using mechanical equipment in Mining Permit Area of West Bangka Regency, Bangka Belitung Islands Province. The mine plan has an ore-gain capacity of 200 m3/hour, requiring the planning of load and haul equipment to meet the ore getting capacity and stripping of overburden and haul geometry in general. Based on the factors that exist in the mine, the load equipment used is the excavator and haul equipment used is Articulared Dumpt Truck. By taking the cycle time as a reference and then converted by the distance of overburden stripping and ore getting activity every year, then can be known the productivity of equipment and the amount of equipment required each activity every year. The number of equipment required is at least 1 load equipment and 4 haul equipment, while the most are 4 load equipment and 13 haul equipment. The geometry of the haul road based on the specification of the haul equipment at the location of the plan has the width of the haul road on a 12 meter straight road, the haul road width at 21 meters, and the 9,1 meter bend radius

Abstract:

The use of environmental impact assessment (EIA) to address the environmental and social impacts of mining is common. At Ok Tedi mine in Papua New Guinea, and Century mine in northern Australia, EIA failed to protect the biophysical and social environment of the mines. A detailed historical analysis was conducted to determine the chronology of the development of these projects, all internal and external decision making, and the reasons for this failure. This analysis showed that EIA was poorly timed and poorly integrated with the early phases of the mine developments. Environmental assessment expenditure and activity were concentrated in the development phase of the project and could not address impacts resulting from the earlier exploration and evaluation phases. Approval processes, such as permits and licences, that did occur in the early phases of the life of the mines, had very limited components of environmental appraisal or control. The primacy of development schedules, and the lack of communication between actors in the development of these large-scale projects, prohibited effective assessment and produced EIAs that were in many ways unrelated to the real environmental information needs of the project. In such large-scale projects it is essential to link EIA (and other approval/appraisal hoops) to environmental issues and decisions which occur throughout the continuum of mine development.

Abstract:

Since the beginning of the 20th century, more than 370 villages with a total amount of about 120,000 inhabitants have been relocated in Germany due to open-pit lignite mining. The devastation of villages and resettlement of their inhabitants had and still have massive implications on the rural landscape and settlement structure of the region. The planning of the relocations reflects, to a great extent, social, economic, and political change in post-war Germany, as well as development in town planning and architectural concepts. The paper focuses on there settlements that took place due to the surface mine of Welzow-Süd (Lusatia, southern Brandenburg), where the development of the resettlement practices of the GDR since the late 1960s and after reunification up until today can be studied in one single open-pit mine.

Abstract:

Based on the PVAR model and taking the data of 10 major coal provinces in China from 2011 to 2020 as an example, the dynamic relationship between coal mine accidents, environmental regulation and economic development is analyzed at the provincial level. Research findings include: (1) From the static relationship between coal mine accidents, environmental regulation and economic development in China’s ten major coal provinces, coal mine accidents promote environmental regulation; environmental regulation inhibits coal mine accidents; economic development strongly promotes environmental regulation; environmental regulation has a weak inhibitory effect on economic development; coal mine accidents slightly inhibit economic development; economic development strongly inhibits coal mine accidents. (2) From the dynamic relationship between coal mine accidents, environmental regulation and economic development in China’s ten major coal provinces, there is a strong dynamic response relationship between environmental regulation and coal mine accidents. The impact of environmental regulation on coal mine accidents shows a decreasing volatility trend, and the impact of coal mine accidents on environmental regulation shows a rising volatility trend. There is a short-term positive interaction between economic development and environmental regulation, but the interaction response relationship between them decreases with time. Economic development has a long-term inhibitory effect on coal mine accidents, while the negative impact of coal mine accidents on economic development has gradually decreased to 0.

Abstract:

Mine dumps or tailings (i.e. ‘mine waste’) created by mining activities are some of the main environmental impacts of mining. Historically little or no regard was given to the environment while planning mine dumps, since planning was based on minimum cost, the availability of land and the safety of underground workings.Mine dumps continue to cause water and air pollution when abandoned without being rehabilitated. Abandoned mines and their dumps are common features of the South African landscape. Section 46 of the Mineral and Petroleum Resources Development Act 28 of 2002 (MPRDA) provides that the state is responsible to rehabilitate abandoned mines if the owner is deceased, cannot be traced, ceased to exist or has been liquidated. Rehabilitation of these mines has extensive financial consequences for the state and indirectly to the taxpayer.The aim of this article is to determine the responsibility of historical mining right holders for such rehabilitation. ‘Historic polluters’ refer to mining companies who caused pollution and environmental degradation due to mining activities before the Minerals Act came into force in 1991. Also to be addressed in this article is the question whether owners of tailings created through an authorisation issued in terms of the now repealed Minerals Act or prior legislation (old order dumps) would be able to escape their rehabilitation obligations or not. Reference will be made to the new proposed amendments to the MPRDA as well in addressing the question.
