Bergbau in Mosambik - Steinkohlenbergbau in Vergangenheit und GegenwartKrauße, Armin January 2016 (has links)
Erfahrungsbericht zum Steinkohlenbergbau in Mosambik: Die Republik Mosambik ist ein schwach entwickeltes Agrarland mit einer bescheidenen Verarbeitungsindustrie, vorwiegend in den Hafenstädten, und einer Infrastruktur, die viele Wünsche offenlässt. Reich ist das Land an unterschiedlichen Rohstoffen. Neben Vorkommen an NE-Metallen, Tantal, Halbedelsteinen und Erdöl sind die umfangreichen Steinkohlenlagerstätten vor allem in der Provinz Tete am Sambesi zu nennen, die jedoch bis zum Ende des 20. Jahrhunderts nur in sehr bescheidenem Umfang erschlossen waren.

Post-Coal Futures in Central Appalachia: A Critique of the Appalachian Regional Commission and Liberal Economic Development ModelsGore, Caleb William 17 May 2022 (has links)
This project critically evaluates liberal development plans created for Central Appalachia by the Appalachian Regional Commission (ARC) through a historical materialist lens. It demonstrates that these plans and their explicitly liberal origins are not sufficient for the working classes in the region to achieve a sustainable 'post-coal' future. Central Appalachia is one of the most impoverished regions in the United States and its political economy was shaped largely by coal mining that was overseen by absentee proprietors. This mono-economic structure has bred unique political conditions in the region. The economics of coal have historically influenced most political decisions. As the coal industry has declined, the region has been subjected to multitudes of economic development plans from the ARC. However, Central Appalachia still exists as an impoverished peripheral zone within the United States' political economy. This thesis is motivated by the decline of coal and the economic and ecological hardships this has created for the region's working-class, and the urgent need to begin envisioning a post-coal future for the region which avoids the insufficiency of liberal economic development. The thesis is not purely an attack on the ARC as an organization, but is rather a critique of the methods they use to enact economic development and shows how these methods are not only inadequate for the Appalachian working class, but all working classes subjected to the liberal economic development model. / Master of Arts / This paper evaluates the efficacy of the Appalachian Regional Commission (ARC) economic development plans. The ARC is the federal agency tasked with reducing poverty in the Appalachian region and was created in 1965. They have enacted over 28,000 development plans and spent $4.5 billion since 1965, but Appalachia is still relatively impoverished in comparison to the rest of the United States. This impoverishment is largely due to the prevalence of the coal industry in the region and the fact that most political and economic decisions were influenced by the coal industry. However, the industry has been declining for several decades now, and this has created economic hardship for many in the region, as there are very few industries that have taken its place, leading to widespread unemployment. This paper focuses specifically on the Central Appalachian region of Southeastern Kentucky, Southwest Virginia, Northeastern Tennessee, and West Virginia. These states had the highest amount of people employed in the coal industry during its heyday, so they have borne the brunt of its decline. I offer a critique of the ARC's model of development and suggest solutions for mitigating the difficult situation in Central Appalachia and explore how the region can achieve a 'post-coal' future that does not rely on the current mechanisms of the ARC's model of development. This critique is informed by historical perspectives that highlight how Central Appalachia was structured as a peripheral zone in the larger US economy that served only to enrich the metropolitan areas of the US and world at great cost to the people of Central Appalachia and their natural environment. I perform my analysis through a historical overview of the economic structure of Central Appalachia as well as a content analysis of six ARC documents that outline their frameworks and methodologies for achieving economic development. While the paper is a critique of the ARC, the emphasis is more so on the particular method that the ARC uses to achieve economic development in the region.

Approaches and Barriers to Incorporating Sustainable Development Into Coal Mine DesignCraynon, John Raymond 30 November 2011 (has links)
It is widely recognized that coal is and will continue to be a crucial element in a modern, balanced energy portfolio, providing a bridge to the future as an important low-cost and secure energy solution to sustainability challenges. The designer of coal mining operations needs to simultaneously consider legal, environmental, and sustainability goals, along with traditional mining engineering parameters, as integral parts of the design process. However, traditional coal mining planning seldom considers key “sustainability factors” such as societal impacts; dislocation of towns and residences; physical and economic impact on neighboring communities and individuals; infrastructure concerns; post-mining land use habitat disruption and reconstruction; and long-term community benefit.
This work demonstrates the advantage of using a systems engineering approach based on the premise that systems can only be optimized if all factors are considered at one time. Utilizing systems engineering and optimization approaches allows for the incorporation of regulatory and sustainability factors into coal mine design. Graphical approaches, based on the use of GIS tools, are shown as examples of the development of models for the positive and negative impacts of coal mining operations. However, this work also revealed that there are significant challenges inherent in optimizing the design of large-scale surface coal mining operations in Appalachia. Regulatory and permitting programs in the United States, which give conflicting and ill-defined responsibilities to a variety of federal and state agencies, often focus on single parameters, rather than the full suite of desirable outcomes for sustainability, and serve as barriers to innovation.
Sustainable development requires a delicate balance between competing economic, environmental and social interests. In the context of coal mining in the U.S., the current regulatory frameworks and policy-guidance vehicles impede this balance. To address this problem, and thus effectively and efficiently provide energy resources while protecting the communities and environments, the U.S. will likely need to fundamentally restructure regulatory programs. Ideally, revisions should be based upon the key concepts of public ecology and allow for a systems engineering approach to coal mine design. / Ph. D.

My Trash, Your Treasure: What Prevents Risk-Based Governance from Diffusing in American Coal Mining Safety Regulation?Yang, Binglin 10 February 2010 (has links)
Recently, there has been a growth of risk-based governance in coal mining safety regulation in many European and commonwealth countries. However, it is puzzling that the progress is much slower in the U.S. This dissertation seeks to explore this puzzle by examining the question what are the barriers keeping the American coal mining industry and the U.S. government from moving toward risk-based governance?
Based on the theoretical framework introduced by Braithwaite and Drahos (2000), particularly the theory of modeling, this research found three major barriers that keep the American coal mining industry from fully embracing the model of risk management. First, the existence of a large number of small operators prevents this model from being diffused in the industry. Second, increasingly prescriptive regulations have consumed the resources that companies could use to develop risk management systems and have created a mentality of compliance that is not compatible with the idea of risk management. Third, a group of model mongers, missionaries, and mercenaries have advocated a competing model — behavior-based safety — that is more attractive to the industry.
This dissertation also found that the lack of three factors helps explain the failure of the U.S. government's move toward risk-based governance: (1) strong imitative pressure from general occupational heath and safety (OHS) regulation; (2) strong model mongers, missionaries, and mercenaries; and (3) webs of dialogue. / Ph.

Temporal and longitudinal extent of surface coal mining influences on water quality and benthic macroinvertebrate communities in central Appalachian headwater streamsCianciolo, Thomas R. 18 June 2019 (has links)
Increased loading of dissolved ions (salinization) and trace elements from surface coal mining is a common alteration to headwater streams in the central Appalachian region. However, temporal and spatial trends of water quality and associated influences on biota in these stream systems have not been well-studied. To address this research need, I analyzed temporal trends in specific conductance, ion matrix, and benthic macroinvertebrate communities in 24 headwater streams, including 19 influenced by surface mining, from 2011-2019. There was limited evidence of recovery of water chemistry or macroinvertebrate communities in these streams, indicating lasting impacts from surface coal mining. Among benthic macroinvertebrates, Ephemeroptera and the scraper functional feeding group were most-impacted by chronic salinization in study streams. In addition, I analyzed spatial patterns of water chemistry in a subset of these streams using synoptic sampling of multiple constituents under baseflow and highflow conditions. Study results indicate that water chemistry is spatially dynamic and can be influenced by both groundwater dilution and inputs from tributaries. Lastly, I investigated patterns in selenium bioaccumulation across and within streams, from particulate matter to top trophic levels (i.e. fish and salamanders). I found that benthic macroinvertebrates had the highest concentrations of selenium in these ecosystems, with lower concentrations in salamander and fish species. However, there was limited evidence of longitudinal trends in bioaccumulation dynamics downstream of mining impacts. Collectively, this work indicates long-term (ca. decades) coal-mining influences but also highlights future research needs to better understand downstream impacts to water quality and biotic communities. / Master of Science / Surface coal mining affects water quality in central Appalachian headwater streams. However, long-term and downstream patterns of impacted water quality and potential effects on aquatic life have not been well-studied. To address this research need, I analyzed trends in water quality parameters and aquatic insect communities in 24 headwater streams from 2011-2019. There was limited evidence of recovery of water chemistry or aquatic life in these streams, indicating lasting impacts from surface coal mining. Certain aquatic insects including Ephemeroptera (mayflies) appear to be more impacted than others by long-term altered water quality. In addition to trends over time, I also analyzed downstream variation in water chemistry in a subset of these streams under baseflow conditions and after a rain event. Results indicate that water chemistry can vary greatly within a stream network and is influenced by tributary inputs and dilution from groundwater. Concentrations of the trace element selenium can also be elevated as a result of surface mining. This is of environmental concern because selenium can biomagnify, where concentrations increase in organisms higher in the food chain and can cause toxic effects. Here, I investigated selenium bioaccumulation patterns across organisms in the food chain and with distance downstream across six headwater streams. I found that aquatic insects had the highest concentrations of selenium, with lower concentrations in salamanders and fish. This work indicates that surface coal mining has longterm (ca. decades) effects on headwater streams, but also points to future research to better understand downstream impacts to water quality and aquatic life.

Development and Demonstration of a Standard Methodology for Respirable Coal Mine Dust Characterization Using SEM-EDXSellaro, Rachel Mary 09 July 2014 (has links)
The purpose of this thesis is to examine the potential for a more comprehensive method of analysis of coal mine dust. Respirable dust is specifically of interest due to its ability to cause occupational lung disease when miners are overexposed to airborne concentrations. A detailed standard methodology to characterize respirable mine dust is carefully investigated with the use of scanning electron microscopy with energy dispersive x-ray (SEM-EDX). In addition to a thorough description of the developed particle level characterization approach, the method is demonstrated with underground respirable dust samples collected from an underground coal mine in Central Appalachia.
Results of this thesis indicate that a comprehensive dust characterization method is possible and can be efficient and effective, when standardized. This analytical approach uses measured compositions, dimensions, and shapes to produce an abundance of data in even a single sample of dust. Verification results show the method is suitable for analysis of respirable particles of common coal mine mineralogy and analysis of many samples in a timely manner. The results obtained from the underground samples in Central Appalachia reveal the quantity of information which can be generated using the developed method. The amount of data which is acquired using the more comprehensive dust characterization method may aid in understanding the health effects of various dust characteristics. / Master of Science
