Dust Control for Haul Roads

Book Description
Throughout the mining and processing of minerals, the mined ore undergoes a number of crushing, grinding, cleaning, drying, and product sizing operations as it is processed into a marketable commodity. These operations are highly mechanized, and both individually and collectively these processes can generate large amounts of dust. If control technologies are inadequate, hazardous levels of respirable dust may be liberated into the work environment, potentially exposing workers. Accordingly, federal regulations are in place to limit the respirable dust exposure of mine workers. Engineering controls are implemented in mining operations in an effort to reduce dust generation and limit worker exposure.
Mining Haul Roads

Book Description
Mining haul roads are a critical component of surface mining infrastructure and the performance of these roads has a direct impact on operational efficiency, costs and safety. A significant proportion of a mine’s cost is associated with material haulage and well-designed and managed roads contribute directly to reductions in cycle times, fuel burn, tyre costs and overall cost per tonne hauled and critically, underpin a safe transport system. The first comprehensive treatise on mining haul road design, construction, operation and management, Mining Haul Roads – Theory and Practice presents an authoritative compendium of worldwide experience and state-of-the-art practices developed and applied over the last 25 years by the three authors, over three continents and many of the world’s leading surface mining operations. In this book, the authors: Introduce the four design components of an integrated design methodology for mining haul roads – geometric (including drainage), structural, functional and maintenance management Illustrate how mine planning constraints inform road design requirements Develop the analytical framework for each of the design components from their theoretical basis, and using typical mine-site applications, illustrate how site-specific design guidelines are developed, together with their practical implementation Summarise the key road safety and geometric design considerations specific to mining haul roads Specify the mechanistic structural design approach unique to ultra-heavy wheel loading associated with OTR mine trucks Describe the selection, application and management of the road wearing course material, together with its rehabilitation, including the use of palliatives Develop road and operating cost models for estimating total road-user costs, based on road rolling resistance measurement and modelling techniques Illustrate the approach of costing a mining road construction project based on the design methodologies previously introduced List and describe future trends in mine haulage system development, how mining haul road design will evolve to meet these new system challenges and how the increasing availability of data is used to manage road performance and ultimately provide 24x7 trafficability. Mining Haul Roads – Theory and Practice is a complete practical reference for mining operations, contractors and mine planners alike, as well as civil engineering practitioners and consulting engineers. It will also be invaluable in other fields of transportation infrastructure provision and for those seeking to learn and apply the state-of-the-art in mining haul roads. “This book is the most definitive treatise on mining haul roads ever written [...] There has never been a text that addresses the many facets of mining haul roads on such a scope [...]” From the Foreword by Jim Humphrey, Professional Engineer, Autonomous haulage systems developer and Distinguished Member of the Society of Mining, Metallurgy and Exploration.

Book Description
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Pages : 459
Book Description
Executive Summary KGHM Ajax Mining Inc. proposes to construct, operate and decommission an open pit copper and gold mine adjacent to the southern limits of the City of Kamloops in British Columbia. The Ajax Mine Project would process up to 65,000 tonnes of ore per day over an operating mine life of up to 23 years. The Ajax Mine Project would have a footprint of approximately 1,700 hectares and would include an open pit, ore processing plant, tailings storage facility, mine rock storage facilities, and water and waste management systems. It would also include upgrades to an existing water intake on Kamloops Lake, a new 16 kilometre water line to transport water to the mine site, and a new 5.3 kilometre natural gas pipeline connecting with the Fortis pipeline near the community of Knutsford. A new 9 kilometre, 230 kilovolt transmission line would tie in with an existing BC Hydro power line near Knutsford to supply electricity to the Ajax Mine Project. The Inks Lake Interchange would be upgraded to provide direct access to the mine site from Highway 5 (Coquihalla Highway). The Ajax Mine Project was subject to review under both federal and provincial environmental assessment legislation, and a coordinated environmental assessment was carried out by the Canadian Environmental Assessment Agency (the Agency) and the BC Environmental Assessment Office (EAO). The Agency and EAO prepared a joint federal Comprehensive Study/provincial Assessment Report that meets the requirements of both the Canadian Environmental Assessment Act and British Columbia’s Environmental Assessment Act, and which will inform separate environmental assessment decisions on the Ajax Mine Project by federal and provincial ministers.

Book Description
A photographic look into the world of vinyl record collectors—including Questlove—in the most intimate of environments—their record rooms. Compelling photographic essays from photographer Eilon Paz are paired with in-depth and insightful interviews to illustrate what motivates these collectors to keep digging for more records. The reader gets an up close and personal look at a variety of well-known vinyl champions, including Gilles Peterson and King Britt, as well as a glimpse into the collections of known and unknown DJs, producers, record dealers, and everyday enthusiasts. Driven by his love for vinyl records, Paz takes us on a five-year journey unearthing the very soul of the vinyl community.
