Book Description
At Campbell Red Lake Mine, Northwestern Ontario, rockburst activities were experienced in some mined-out workings. To determine the stress pattern,three-dimensional field stress measurements were carried out on the 14, 22and 27 levels and biaxial stresses were measured in four boxhole pillars onthe 9, 10 and 14 levels. Maximum stress transfer occurs horizontally acrossthe boxhole pillars, perpendicular to the hanging wall and footwall. Maximum stress magnitudes of 17 to 78 MPa, and minimum stresses of loworder or tensional were measured. The pillar stresses were less than expected. It is concluded that the peak strength of the boxhole pillarshas been exceeded and that these are in post-failure conditions.

Book Description
Historically Canadians have considered themselves to be more or less free of racial prejudice. Although this conception has been challenged in recent years, it has not been completely dispelled. In Colour-Coded, Constance Backhouse illustrates the tenacious hold that white supremacy had on our legal system in the first half of this century, and underscores the damaging legacy of inequality that continues today. Backhouse presents detailed narratives of six court cases, each giving evidence of blatant racism created and enforced through law. The cases focus on Aboriginal, Inuit, Chinese-Canadian, and African-Canadian individuals, taking us from the criminal prosecution of traditional Aboriginal dance to the trial of members of the 'Ku Klux Klan of Kanada.' From thousands of possibilities, Backhouse has selected studies that constitute central moments in the legal history of race in Canada. Her selection also considers a wide range of legal forums, including administrative rulings by municipal councils, criminal trials before police magistrates, and criminal and civil cases heard by the highest courts in the provinces and by the Supreme Court of Canada. The extensive and detailed documentation presented here leaves no doubt that the Canadian legal system played a dominant role in creating and preserving racial discrimination. A central message of this book is that racism is deeply embedded in Canadian history despite Canada's reputation as a raceless society.

Recovering Canada
Author: John BorrowsPublisher: University of Toronto Press
ISBN: 1487516754
Category : Law
Languages : en
Pages : 326
Book Description
Canada is covered by a system of law and governance that largely obscures and ignores the presence of pre-existing Indigenous regimes. Indigenous law, however, has continuing relevance for both Aboriginal peoples and the Canadian state. In his in-depth examination of the continued existence and application of Indigenous legal values, John Borrows suggests how First Nations laws could be applied by Canadian courts, and tempers this by pointing out the many difficulties that would occur if the courts attempted to follow such an approach. By contrasting and comparing Aboriginal stories and Canadian case law, and interweaving political commentary, Borrows argues that there is a better way to constitute Aboriginal / Crown relations in Canada. He suggests that the application of Indigenous legal perspectives to a broad spectrum of issues that confront us as humans will help Canada recover from its colonial past, and help Indigenous people recover their country. Borrows concludes by demonstrating how Indigenous peoples' law could be more fully and consciously integrated with Canadian law to produce a society where two world views can co-exist and a different vision of the Canadian constitution and citizenship can be created.
The History of the London Water Industry, 1580–1820

Pages : 331
Book Description
How did pre-industrial London build the biggest water supply industry on earth? Beginning in 1580, a number of competing London companies sold water directly to consumers through a large network of wooden mains in the expanding metropolis. This new water industry flourished throughout the 1600s, eventually expanding to serve tens of thousands of homes. By the late eighteenth century, more than 80 percent of the city’s houses had water connections—making London the best-served metropolis in the world while demonstrating that it was legally, commercially, and technologically possible to run an infrastructure network within the largest city on earth. In this richly detailed book, historian Leslie Tomory shows how new technologies imported from the Continent, including waterwheel-driven piston pumps, spurred the rapid growth of London’s water industry. The business was further sustained by an explosion in consumer demand, particularly in the city’s wealthy West End. Meanwhile, several key local innovations reshaped the industry by enlarging the size of the supply network. By 1800, the success of London’s water industry made it a model for other cities in Europe and beyond as they began to build their own water networks. The city’s water infrastructure even inspired builders of other large-scale urban projects, including gas and sewage supply networks. The History of the London Water Industry, 1580–1820 explores the technological, cultural, and mercantile factors that created and sustained this remarkable industry. Tomory examines how the joint-stock form became popular with water companies, providing a stable legal structure that allowed for expansion. He also explains how the roots of the London water industry’s divergence from the Continent and even from other British cities was rooted both in the size of London as a market and in the late seventeenth-century consumer revolution. This fascinating and unique study of essential utilities in the early modern period will interest business historians and historians of science and technology alike.
