Annual Review and Forecast of Utah Coal Production and Distribution — 2007

Book Description
Utah’s coal industry experienced a difficult and tragic year in 2007. The terrible circumstances surrounding the unexpected closure of the Crandall Canyon mine, followed by the idling of the Aberdeen mine, resulted in a 7.1% decrease in Utah coal production to a total of 24.3 million short tons. These closures also resulted in a 5.3% loss in mine-related employment. In addition, difficult mining conditions at Canyon Fuel Company’s SUFCO and Dugout Canyon mines contributed to production declines. On the brighter side, Canyon Fuel’s Skyline mine, with a full-year of longwall operation, increased its production by 45.4% and UtahAmerican’s West Ridge mine increased its production by 34.3%. Also noteworthy are record production for both Carbon County and State lands, and a 20-year high in the average price for a short ton of Utah coal: $25.18. Distribution of Utah coal decreased slightly in 2007 to 24.5 million short tons, while out-of-state coal imports hit a 20-year low of only 1.5 million tons.

Book Description
Governance of the World’s Mineral Resources: Beyond the Foreseeable Future provides in-depth information on the geological scarcity of mineral resources. The book demonstrates the urgent need to implement sustainable utilization of mineral resources, in order to ensure that these resources will be sufficiently available for future generations too. The availability of resources, especially for modern technologies, is an increasingly important issue. Some key mineral resources are so geologically scarce that their availability for future generations may not only become substantially less, but also much less affordable than for the current generation unless timely measures are taken. This book provides detailed data and calculations of the availability of mineral resources. The book elaborates on whether and how it is possible to keep providing sufficient mineral resources to a growing world population, and for how long. The book details also how and for how much time it will be possible for all countries, worldwide, to achieve and maintain service delivery of raw materials to their population at levels equivalent to those in developed countries in 2020. Governance of the World’s Mineral Resources: Beyond the Foreseeable Future is therefore an important source of knowledge for postgraduates, academics and researchers in the fields of environmental science, sustainability, and geology, as well as anyone in the field of mining and economics who need to account for sustainable provision of mineral resources. Provides a thorough overview of all considerations related to a sustainable production rate of mineral resources Comprehensively details scarce mineral resources and describes their applications, worldwide in-use stock increases, and sustainable production rates Covers all aspects of a sustainable production rate of mineral resources, detailing the current challenges and possible global solutions, both technically and from a policy point of view Includes detailed studies of thirteen different scarce mineral resources and extensive quantitative data from recent studies and in-depth research
