A row of brick-built houses with slate roofs, at the edge of a large mining village in Staffordshire. The houses are dingy and colourless, and without relief of any kind. So are those in the next row, so in the street beyond, and throughout the whole village. There is a dreary monotony about the place; and if some giant could come and pick up all the rows of houses, and change their places one with another, it is a question whether the men, now away at work, would notice any difference whatever until they entered the houses standing in the place of those which they had left in the morning. There is a church, and a vicarage half hidden away in the trees in its pretty old-fashioned garden; there are two or three small red-bricked dissenting chapels, and the doctor's house, with a bright brass knocker and plate on the door. There are no other buildings above the common average of mining villages; and it needs not the high chimneys, and engine-houses with winding gear, dotting the surrounding country, to notify the fact that Stokebridge is a mining village.
This book provides insights into the development and usage of coal in chemical engineering. The reactivity of coal in processes such as pyrolysis, gasification, liquefaction, combustion and swelling is related to its structural properties. Using experimental findings and theoretical analysis, the book comprehensively answers three crucial issues that are fundamental to the optimization of coal chemical conversions: What is the structure of coal? How does the underlying structure determine the reactivity of different types of coal? How does the structure of coal alter during coal conversion? This book will be of interest to both individual readers and institutions involved in teaching and research into chemical engineering and energy conversion technologies. It is aimed at advanced- level undergraduate students. The text is suitable for readers with a basic knowledge of chemistry, such as first-year undergraduate general science students. Higher-level students with an in-depth understanding of the chemistry of coal will also benefit from the book. It will provide a useful reference resource for students and university-level teachers, as well as practicing engineers.
Christopher Kennedy University of Toronto, Department of Civil Engineering, 35 St. George Street, Toronto, Ontario, Canada M5S IA4 Coal is a valuable resource. It provides a significant amount of the World's energy supply and it is the basis for many industries. However, in areas where coal lies close to the Earth's surface and has been exploited by open cast tech- niques, radical alterations of landscape and significant impacts on the envi- ronment have occurred. This report was prepared to provide guidance to those who are responsible for the prevention of environmental effects from surface mining and for the restoration of the mining areas. Environmental problems of surface coal mining and restoration of the mine sites are discussed in the re- port. Particular attention is given to Eastern Europe, which continues to be a major centre of opencast lignite mining. Reclamation of mined lands for for- estry, agriculture and wildlife is briefly discussed. However, the shear volume of coal removed from many mines in Eastern Europe is so vast, that there is often insufficient overburden material to refill the pits. Consequently, the main focus of this report is on the creation of lakes in these former surface mines. Many problems have to be overcome in creating healthy lakes for recreation or wildlife. Guidelines for treating water quality problems and further devel- opment of lakes are provided. Techniques for dealing with acidic, waters, eutrophication and contamination are discussed.
