Chapter 1 provides a broad theoretical, historical, and ethnographic context to the research, and an overview of the major research questions addressed in the book. Topics such as the approach to the structural violence of everyday life in the twentieth century, the relationship between migrants and the sovereignty of political states, racialization, and the labor needs of late industrial capitalism are addressed. Relevant theoretical concepts from scholars such as Giorgio Agamben, Walter Benjamin and Karl Marx are introduced here. The ethnographic and discursive context of immigrant discrimination in the present, and the manner in which it informs the broad trajectory of the research is presented. Lastly, the manner in which interdisciplinary data is applied to this research is also presented.

At the present time the problem to search for variants for the development of steep thick coal seams is highly interest. Here there are, for example, variants for managing the workings’ roof by caving or laying the worked out space. The authors proposed a number of methods for it, which are protected by patents. The permissible span of the roof exposure is estimated as a function of the type of the immediate roof of the mine, its thickness, bulk density and tensile strength, and the height of the underlevel is also determined. The technical result is provided by the presence of the protective inter-horizon strips and inter-sectional pillars, by the order of working out the excavation site and by the value of the step of the binding of the worked out space. The above solutions are acceptable for the Prokopyevsk-Kiselevsk coal region in Kuzbass.

In 1937, in one of the northern Appalachian coal States, a new charitable corporation was formed, the purpose of which, as stated in the by-laws, was: ‘…… the rehabilitation and assistance of industrial and agricultural workers …… unable to obtain sufficient suitable employment ……’. The intention of this corporation was to concentrate on finding a solution for the situation created by the mass unemployment of stranded coal miners in the Appalachian coal fields.
