Book excerpt: 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.

This book was released on 2012 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: Haul road pavement condition has long been considered as having a significant influence on the efficiency of haulage in surface mining. However limited literature exists relating wearing course condition with performance, resulting in mine operators not maximising the potential value of their haul road assets. This project focuses on defining current issues associated with the functional performance of haul roads, through a case study involving three iron ore mines in the Pilbara region of Western Australia. Consequently attempts are then made to relate material properties to performance so that existing criteria can be verified or refined. Cementitious stabilisation and naturally occurring gravels found adjacent to the mines involved in the case study are then trialled via laboratory testing, show promise and lead to a recommendation of subsequent field trials. Pavement lifetime costing is finally completed with the Pilbara environment as the basis, utilising the most appropriate models currently available for pavement condition and vehicle operating and maintenance costs. This resulted in a lack of variability due to material properties, with maintenance variables having a greater effect. Lastly it is found that potential production loss values (net reduction in ore hauled) outweigh expenditure on improved maintenance practice or even material treatments.

Available in PDF, EPUB and Kindle. Book excerpt: Unpaved mine haul roads provide the principal means of material transport on surface strip coal mines. With the expansion of surface mining in South Africa and in particular coal strip mining, the use of ultra-heavy off-highway trucks, currently capable of hauling payloads in excess of 160t, has become commonplace. Design and management of these roads was based primarily on local experience and adopted empirical guidelines. This design method served its purpose in an era when off-highway trucks were lighter and less financial outlay was required, both in terms of initial pavement construction costs, ongoing road maintenance costs and vehicle maintenance costs. As the trend in increasing truck size continues, these current pavement design and management systems proved inadequate. Not only would the maintenance costs of existing roads increase, vehicle operating and maintenance costs would also increase prohibitively. The primary objective of this research was the development of a portable and practical total haul road design and management methodology that encompasses both pavement strength, wearing course functionality and road maintenance management components. The structural design concerns the ability of a haul road to carry the imposed loads without the need for excessive maintenance. A revised mechanistically derived structural design is presented together with the associated limiting design criteria and recommended target effective elastic modulus values for the construction materials available. The placement of those materials as pavement layers, such as to optimise their performance both as individual layers and over the entire structure is analysed. Functional design aspects refer to the ability of the haul road to perform its function, i.e to provide an economic, safe and vehicle friendly ride. This is dictated to a large degree through the choice, application and maintenance of wearing course materials. The development and analysis of suitable material selection guidelines for use in haul road functional design was allied to the development of a qualitative defect assessment and ranking methodology in order to assess the utility of established performance related selection guidelines and as a basis for revised functional performance parameter specification. A revised range of parameters was derived based on road-user acceptability criteria. By analysing the trends evident in the individual defect rankings, the predictive capability of the specification was enhanced by depicting the typical functional defects arising when departures are made from the recommended material property limits. Maintenance design concerns the optimal frequency of wearing course maintenance commensurate with minimum vehicle operating and road maintenance costs. A qualitative road roughness evaluation technique was developed as a precursor to the development of a model for roughness progression. Expressions were developed to enable direct comparison to be made between the qualitative roughness defect score and International Roughness Index (IRI). The second element of a maintenance management system was based on models of the variation of vehicle operating and road maintenance costs with a road roughness model. The combination of these models enabled the optimal maintenance strategy to be sought based on the minimisation of these costs. Sub-optimal maintenance strategies were seen to be associated with unwarranted expenditure on total road-user costs. This thesis makes a contribution to the state of knowledge through the development and synthesis of structural, functional and maintenance management aspects of haul road design. The adoption of these revised and improved haul road design methodologies are associated with potentially significant cost savings and operational improvements. AFRIKAANS: Ongeplaveide mynvervoerpaaie voorsien die prim? re vervoer metode van materiaal in steenkoolstrookdagmyne. Met die uitbreiding van dagmynbou in Suid-Afrika en in besonder in die steenkoolstrookmynbou, het die gebruik van swaar vervoertrokke alledaags geword. Ontwerp en bestuur van hierdie paaie was hoofsaaldik gebaseer op plaaslike ondervinding en empiriese riglyne. Hierdie ontwerp metode het sy doel gedien in 'n tydperk waarin die trokke ligter en 'n kleiner finansiele uitleg nodig was, beide in tenne van inisiele plaveisel konstruksie kostes en voortdurende padonderhoudskostes en voertuig instanthoudingkostes. Soos wat die tendens van toename in trokgrootte voortduur, sal die huidige plaveisel ontwerp en bestuursstelsels onvoldoende wees. Nie aIleen sal die ondershoudskostes van bestaande paaie verhoog nie, maar voertuigbedryf en -instandhoudingkostes sal buitensporig word. Die prim? re doel van die navorsing was die ontwikkeling van 'n oordraagbare en praktiese totale vervoerpadontwerp en bestuursmetodiek wat die plaveiselsterkte, slytlaag funksionele werkverrigting en padonderhoudbestuur komponente insluit. Die strukturele ontwerp behels die vermoe van 'n vervoerpad om die toegepaste las te kan dra sonder die noodsaaklikheid van buitensporige onderhoud. 'n Hersiene meganisties strukturele ontwerp word aangebied tesame met die geassosieerde ontwerpkriterium en aanbevole effektiewe elastisiteitsmoduluswaardes vir die beskikbare konstruksie materiaa1. Die plasing van daardie materiale as plaveisellae, om sodanig hulle werkverrigting te optimeer is, as beide individuele lae en oor die hele struktuur, geanaliseer. verrig, naamlik om 'n ekonomiese, veilige en voertuigvriendelike rit te voorsien. Die ontwikkeling en analise van geskikte materiaal seleksie is gekoppel aan die ontwikkeling van 'n kwalitatiewe defek waardebepaling en ranglys metodiek om die bruikbaarheid van vasgestelde prestasie-verwante seleksie riglyne te kan bepaal en as basis vir hersiene funksionele prestasie parameter spesiftkasies. 'n Hersiene reeks parameters is afgelei, gebaseer op padverbruiker aanvaarbaarheids kriterium. Deur analise van die tendens in die individuele defek ranglys, is die voorspelbaarheids vennoe van die spesifIkasies verhoog deur die uitwysing van tipiese funksionele defekte wat voorkom wanneer afgewyk word van aanbevole materiaal parameter beperkings. Die onderhoud aspek van vervoerpad ontwerp kan nie afsonderlik van die strukturele en funksionele ontwerp aspekte oorweeg word nie. Onderhoudontwerp behels die optimale frekwensie van slytlaag onderhoud eweredig aan die minimum. voertuigbedryf en padonderhoudskostes. 'n Kwalitatiewe pad ongelykheid evaluasie tegniek is ontwikkel as 'n voorloper tot die ontwikkeling van 'n ongelykheid progressie model. Uitdrukkings is ontwikkel om direkte vergelyking tussen ongelykheid defektelling en Internasionale ongelykbeids indeks (IRI) moontlik te maak. Die tweede element van 'n onderhouds bestuurstelsel is gebaseer op modele van die variasie van die voertuigbedryf en instandhoudingkoste en padongelykbeid. Die kombinasie van hierdie modelle stel die verbruiker in staat om die optimale onderhoudstrategie te soek. 'n Sub-optimale padonderhouds strategie was geassosieer met buitensporige besteding op totale padverbruikers koste. Hierdie proefskrif lewer 'n bydrae tot die staat van kennis deur die ontwikkeling en samevoeging van die strukturele, funksionele en onderhoud bestuurs aspekte van mynvervoerpadontwerp. Die ingebruikneming van die hersiene en verbeterde vervaerpad antwerp en bestuur metodiek het die potensiaal am beduidende koste besparings te verwesenlik.

This book was released on 2015-05-09 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
