This book intends directly the practical engineers, who will be of
great interest in reading the interesting chapters. Earthwork
projects are critical components in civil construction and often
require detailed management techniques and unique solution methods
to address failures. Being earthbound, earthwork is influenced by
geomaterial properties at the onset of a project. Hence, an
understanding of the in-situ soil properties and all geotechnical
aspects is essential. Analytical methods for earth structures
remain critical for researchers due to the mechanical complexity of
the system. Striving for better earthwork project management, the
geotechnical engineering community continues to find improved
testing techniques for determining sensitive properties of soil and
rock, including stress wave-based, non-destructive testing methods.
To minimize failure during earthwork construction, past case
studies and data may reveal useful lessons and information to
improve project management and minimize economic losses.
This book presents a collection of papers on topics in the field of
strategic mine planning, including orebody modeling, mine-planning
optimization and the optimization of mining complexes. Elaborating
on the state of the art in the field, it describes the latest
technologies and related research as well as the applications of a
range of related technologies in diverse industrial contexts.
This book deals with the history of mining and smelting from the
Renaissance to the present. Martin Lynch opens with the invention,
sometime before 1453, of a revolutionary technique for separating
silver from copper. It was this invention which brought back to
life the rich copper-silver mines of central Europe, in the process
making brass cannon and silver coin available to the ambitious
Habsburg emperors, thereby underpinning their quest for European
domination. Lynch also discusses the Industrial Revolution and the
far-reaching changes to mining and smelting brought about by the
steam engine; the era of the gold rushes; the massive mineral
developments and technological leaps forward which took place in
the USA and South Africa at the end of the 19th century; and,
finally, the spread of mass metal-production techniques amid the
violent struggles of the 20th century. In an engaging, concise and
fast-paced text, he presents the interplay of personalities,
politics and technology that have shaped the metallurgical
industries over the last 500 years.
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 focuses on the fundamental concept of and current
endeavors in "urban mining" among those who are interested in both
metal resources and ecology. Systems for recycling and reusing
precious metals and rare-earth minerals contained in used and
discarded electronics are introduced in this book. The target
audience is not academic researchers in the resource management and
ecology fields but, rather, citizens who are concerned about our
future environment and want to do something for the future.
The Eyes of the World focuses on the lives and experiences of
Eastern Congolese people involved in extracting and transporting
the minerals needed for digital devices. The digital devices that,
many would argue, define this era exist not only because of Silicon
Valley innovations but also because of a burgeoning trade in dense,
artisanally mined substances like tantalum, tin, and tungsten. In
the tentatively postwar Eastern DR Congo, where many lives have
been reoriented around artisanal mining, these minerals are
socially dense, fueling movement and innovative collaborations that
encompass diverse actors, geographies, temporalities, and
dimensions. Focusing on the miners and traders of some of these
"digital minerals," The Eyes of the World examines how Eastern
Congolese understand the work in which they are engaged, the forces
pitted against them, and the complicated process through which
substances in the earth and forest are converted into commodified
resources. Smith shows how violent dispossession has fueled a
bottom-up social theory that valorizes movement and
collaboration-one that directly confronts both private mining
companies and the tracking initiatives implemented by international
companies aspiring to ensure that the minerals in digital devices
are purified of blood.
This book gives a rigorous and up-to-date study of the various AI
and machine learning algorithms for resolving environmental
challenges associated with blasting. Blasting is a critical
activity in any mining or civil engineering project for breaking
down hard rock masses. A small amount of explosive energy is only
used during blasting to fracture rock in order to achieve the
appropriate fragmentation, throw, and development of muck pile. The
surplus energy is transformed into unfavourable environmental
effects such as back-break, flyrock, air overpressure, and ground
vibration. The advancement of artificial intelligence and machine
learning techniques has increased the accuracy of predicting these
environmental impacts of blasting. This book discusses the
effective application of these strategies in forecasting,
mitigating, and regulating the aforementioned blasting
environmental hazards.
The book is a comprehensive treatment of the application of
geotechnical engineering to site selection, site exploration,
design, operation and closure of mine waste storage
facilities.
The level and content are suitable as a technical source and
reference for practising engineers engaged both in the design and
operational management of mine waste storage facilities and for
senior undergraduate and postgraduate students. The thirteen
chapters follow the sequence of the life cycle of a waste storage
facility (characterization, site selection, geotechnical
exploration, environmental aspects, testing and compaction) and
also consider the use of mine waste as a construction
material.
The text is liberally illustrated by both line drawings and
photographs, and the theoretical passages are supported by typical
test results, worked examples and carefully analysed case
histories.
Rock physics encompasses practically all aspects of solid and fluid
state physics. This book provides a unified presentation of the
underlying physical principles of rock physics, covering elements
of mineral physics, petrology and rock mechanics. After a short
introduction on rocks and minerals, the subsequent chapters cover
rock density, porosity, stress and strain relationships,
permeability, poroelasticity, acoustics, conductivity,
polarizability, magnetism, thermal properties and natural
radioactivity. Each chapter includes problem sets and focus boxes
with in-depth explanations of the physical and mathematical aspects
of underlying processes. The book is also supplemented by online
MATLAB exercises to help students apply their knowledge to
numerically solve rock physics problems. Covering laboratory and
field-based measurement methods, as well as theoretical models,
this textbook is ideal for upper-level undergraduate and graduate
courses in rock physics. It will also make a useful reference for
researchers and professional scientists working in geoscience and
petroleum engineering.
This book addresses the practice of geostatistical simulation to
evaluation of mineral reserves, prediction of recovered tonnages
and mineral grades and the impact of mining dilution. Such
prediction is absolutely critical for mine planning and investment
decisions, yet it cannot be made on maps directly interpolated from
present data. Various dilution factors need to be introduced to
account for - the support effect: mining unit volumes are vastly
different from composite data unit volumes - the information
effect: future selection of ore/waste will be based on vastly
different data than that presently available. Geostatistical
simulations allow a rigorous evaluation of these effects on
reserves recovery. These stochastic simulations have the potential
to be for the mining industry what a wind tunnel is for aircraft
design. This book is written by two expert
geostatisticians--Journel is the pioneer of mining
geostatistics--and established academics.

The role of hydrothermal fluids during the crystallization of
layered intrusions and the ore deposits they contain has long been
debated. This book summarizes the evidence for fluid-crystal-liquid
(hydromagmatic) interactions and their importance for the
understanding of the formation of platinum-group deposits in
layered intrusions. It discusses the composition of igneous fluids
in mafic magmatic systems, the generation and movement of these
fluids in layered intrusions, their impact in altering the
mineralogy and composition of the originally precipitated
assemblages, and their role in the transport of the platinum-group
elements (PGE). Using examples from the Bushveld complex of South
Africa and other intrusions, this book provides a comprehensive
overview of the hydromagmatic model for the origin of various
features of layered intrusions. It is a useful reference for
academic researchers and professional geologists working on
economic mineral exploration, layered igneous intrusions, and
hydrothermal metallogenesis.
