The unique culture of the hardrock mining town is exposed through the eyes of retired miners, young welfare mothers, and children. In spite of great adversity, Cobalt remains a distinctive and cohesive working-class community
This SME classic is both a reference book for the working engineer and a textbook for the mining student. This hardcover edition gives a brief history of surface mining and a general overview of the state of surface mining today--topics range from production and productivity to technological developments and trends in equipment. This extremely useful text takes the approach that exploration and mining geologists must be expert in a number of fields, including basic finance and economics, logistics, and pragmatic prospecting. Readers will find material on all these topics and more. The book's nine chapters include: Introduction, Exploration and Geology Techniques, Ore Reserve Estimation, Feasibility Studies and Project Financing, Planning and Design of Surface Mines, Mine Operations, Mine Capital and Operating Costs, Management and Organization, and Case Studies. The book is fully indexed.
Proceedings of the 4th International Symposium held in Montreal, Oct.2-5, 1989. Paper topics include: review, laboratory testing, modelling and design, rockburst control, soft rock mining, and system design.
Includes entries for maps and atlases.
Geophysical prospecting is an applied science and the range of scientific principles to be applied is very wide. In this collection of original papers, the application of many different principles is described in the search for sulphides, other metallic ores and radioactive deposits. The papers are all concerned with surface observations and cover both the theory and the practice of the methods used. In all cases the advan tages and disadvantages of the methods are described and their role in the detection of mineral deposits is discussed and placed in context. Electromagnetic methods are covered in detail, involving the use of both electric and magnetic field effects. Techniques are described involv ing observations both at a number of discrete frequencies and with continuously changing frequency. In spite of the diversity of method it is interesting to note the strong links between the papers; two chapters, for example, start from the same fundamental illustration, first published by Won, of the basic relationship between source frequency, ground con ductivity and depth of penetration. The all-important economic aspects are not forgotten and the first chapter assesses the statistics of performance and describes their use in the shaping and management of an exploration programme. The editor takes this opportunity to thank the busy men who have set aside time to write these contributions.
Mirrors of Stone delves into the many ethnic cultures that thrived in the mining areas of Northern Ontario from the 1920s to the 1960s. The stormy history of hardrock mining camps has never fit into the comfortable cliches by which Canada tells its story. Angus unearths the dark sides of this history-the wild tales of bootleggers, mobsters, and prostitution rings' and in so doing opens up new ways of seeing Ontario's history and culture. This is Angus' third work on the economic and cultural history of Northern Ontario, and the second collaboration between Angus and Louie Palu. We Lived a Life and Then Some (BTL, 1996) tells the marvelous story of Cobalt, Ontario, and Industrial Cathedrals of the North (BTL, 1999) portrays in images and words the ghostly mining structures now largely abandoned in the north.
