The subsidence characteristics of the Collie Basin sediments have been investigated to provide site specific design criteria for the Wongawilli method of coal extraction. As historical coal extraction (bord and pillar) methods did not generally give rise to large scale subsidence, there were very few details on mining subsidence in the Collie Basin available to base any design methodology on. Consequently, the investigation was conducted on a Green fields basis. Firstly, the mechanisms involved in the development of mining subsidence needed to be investigated and identified. It was then necessary to determine the effects that mining subsidence would have on mine and ground mass (specifically aquitards) structures and surface features. Once these two areas of work were completed, design criteria were formulated to manage the effects of mining subsidence by controlling the critical mechanisms of subsidence development.The results from this study have greatly enhanced the level of understanding of the subsidence mechanisms involved, and allowed for the development of predictive models which can be used for the design of coal extraction by the panel/pillar mining method in the Collie Basin. Mine planning engineers can now use this design information to derive the most cost effective methods for the extraction of coal within the Collie Basin.

Many historians have presented the narrative of Canada’s Second World War experience as a “good” war. Individuals and communities came together in patriotism and a common purpose to furnish the national war effort with military manpower, labour, financial contributions, and voluntary efforts. As the dark years of the Great Depression gave way to unprecedented levels of industrial and economic growth, falling unemployment rates, increased urbanization, and a wealth of social programs, Canada’s future was bright. However, this optimistic picture is not representative of Canada as a whole. Some regions fared better than others, and industrial Cape Breton was one of those that benefited the least from the opportunities presented by the war. Glace Bay, Cape Breton’s largest mining town and long-time hotbed of industrial strife and labour radicalism, serves as an ideal case study of the region’s largely unprofitable and unchanging wartime experience. Long plagued by poverty, poor living conditions, and underdeveloped industry, and desperately seeking to break free of its destitution, Glace Bay tried and failed to take advantage of wartime opportunities for industrial diversification and local improvement.

The need and longing to connect to another is a fundamental desire of the human heart, enforcing a sense of movement toward social and personal security and, moreover, the future. Yet it is paradoxical that, where people are the most closely crowded together, feelings of alienation and loneliness are often the greatest. We live in times of busy isolation, on streets where we dont know our neighbours, in societies where our lives are lived behind closed doors. As the global village grows, our personal worlds shrink, both by circumstance and by choice. Our innate, gregarious nature faces its greatest challenge, or ultimate defeat.<p> The story of my hometown, New Waterford, is a substantial element in the story of my life as well as my art. The woodcuts and many of the paintings in the exhibition, Slag, are documentations of this place, its inhabitants and their way of life. It is a town with a unique character resulting from the circumstances surrounding its relationship to coalmininga town that is withering away now that the mines are gone. Other paintings in the exhibition depict people and spaces from other places that I have lived. Though the environments change, there are similarities in the pathos of the human subjects that remain constant. In my work, whether I am depicting the inhabitants of a hollowed out town or the solitary subway commuter, they are united as those things that have been lost or left behind in the name of progressthe leftovers and waste: the slag.

Carbon Technocracy argues for the centrality of fossil fuel energy to the making of global industrial modernity and to the emergence of East Asian technocratic imaginaries in the first half of the twentieth century. It advances the premise that coal and later oil enabled not only the transformation of human society&rsquo;s material foundations, but also allowed for new kinds of publics and politics. / East Asian Languages and Civilizations

The extraction of natural resources can lead to higher incomes and standards of living for local areas, but resource exploitation, a lack of broad economic development, and an excess amount of environmental pollution can come with this activity. This dissertation analyzes the short and long run economic, public health, and demographic consequences of economic development via natural resources. It expands upon the current non-renewable resource extraction, "resource curse," and local community health literatures by using county data for the entire U.S. spanning over a century, capturing both short and long run impacts over various time periods, on net-migration, mortality, natality, local economic activity, and environmental impacts. What drove coal production in the U.S. during the twentieth century? How effective were the operators at predicting and responding to changes in price? Did coal mining industries provide broad economic benefits to local communities in non-mining sectors? Did the impacts differ over time? Has natural resource extraction activity caused mortality in the area to increase? To answer these questions I collected, compiled, and digitized a long run panel database of county level mining activity, mortality, natality, and pollution spanning the entire U.S. The dissertation identifies the short and long run net effects of natural resource extraction activity with time-varying measures, and an IV approach that isolates changes in local mining activity independent of local conditions and outcomes. The dissertation shows that coal producers responded to variation in prices, and were aware and responded to past price behavior. Chapter 3 shows increased levels of coal production had positive net impacts on county population and manufacturing employment over an initial ten year span, then became negative over the subsequent decade. This provides evidence that the existence of a "resource curse" on local manufacturing is a long run phenomena. Chapter 4 shows that extraction activity increased infant and total mortality, had no impact on contemporaneous total cancer mortality, and may be driven by areas where coal mining was historically prevalent. Past and present mining activity is strongly related to local pollution, supporting the idea that increasing local environmental pollution increases mortality.

Following three major mining accidents in 2006, the MINER Act of 2006 was enacted by MSHA and required every underground coal mine to install refuge alternatives to help prevent future fatalities of trapped miners in the event of a disaster. The following research was performed in response to NIOSH’s call for the investigation into new refuge alternatives. A 15 psi safe haven polycarbonate wall for use in underground coal mines was designed and modeled using finite element modeling in ANSYS Explicit Dynamics. The successful design was tested multiple times in both half-scale and small scale using a high explosive shock tube to determine the walls resistance to blast pressure. The safe haven wall design was modeled for an actual underground coal mine environment to determine any responses of the wall within a mine. A full scale design was fabricated and installed in an underground coal mine to determine any construction constraints and as a final step in proof of concept for the safe haven design.

The purpose of this study was to examine the apparent contrast between community expectations concerning Slavic immigrants in the anthracite region of northeastern Pennsylvania in the late nineteenth century and the actual behavior of the immigrants. While established groups in the anthracite fields, and American society at large, expected that the immigrants would threatenwage scales in the anthracite industry, primary evidence indicates that the Slavs did not do so. However, the community expectations proved to be so strong that almost all accounts of the immigration of Slavic labor assert that the many union failures, and the traditionally depressed wages in the anthracite region, were the result of the eastern European influx.The contrast between the community expectations and the actual behavior of the Slavic immigrants is illustrated in the presentation of three case studies. The first is a study of the content of a Scranton, Pennsylvania newspaper, the Scranton Republican, which concentrates on latent and overt anti-immigrant biases in editorial and reportorial copy. This study also reviews the content of the publications of contemporary observers and scholars which are shown to contain anti-Slavic biases as well. A second study examines the emergence of the Polish National Catholic Church, which demonstrates the ability of the immigrants to manipulate complex American insititutions such as the court system, and to create for themselves a complicated formal structure to meet their spiritual needs. This was done in the face of vigorous opposition by the Roman Catholic Diocese of Scranton. Lastly, this thesis contains a study of the organization .of the United Mine Workers union in the anthracite region, which shows that it was the Slavic immigrant workers who made the unionization of the anthracite industry possible, after fifty years of failure by the established American, Welsh, and Irish miners.This contrast between historical fact and social perception is explained by using the hypothesis proposed by social psychologist Erving Goffman, and modified by sociologists Peter Berger and Thomas Luckmann. That thesis asserts that social reality is based on perceptions of events, rather than the events themselves. Since those perceptions are based on social expectations, it can be said that, in the case of the Slavic anthracite workers the negative expectations of American society concerning the eastern Europeans produced negative conclusions concerning their behavior, despite much evidence to the contrary. Those negative conclusions remained in the literature of the anthracite industry until the publication of a study by historian Victor Greene, The Slavic Community on Strike, in 1968, which finally revised the record concerning the Slavic mine workers.While the conclusions reached in this study remain tentative, pending comparative studies in other geographic locations and industries would seem to support the position that intergroup friction is sometimes the result of faulty perceptions on the part of a dominant group rather than any real threat posed by a minority. The possibility that prejudice has primarily cultural rather than economic roots may offer an alternative to the present emphasis on economic opportunity in the efforts to eradicate discrimination within American society.
