Advances in Coal Mine Ground Control is a comprehensive text
covering all recent advances in coal mine ground control, the most
advanced subsystem of the rapidly advancing coal mining systems.
This complete resource is written by Professor Syd Peng who,
alongside leading experts from the world's major coal producing
countries, has contributed extensively to the understanding of
subsidence from underground coal mining, longwall operations and
ground control in underground mines. Syd and the team of
contributors bring together key advances from the past decade into
one comprehensive resource that is accessible to all those
studying, researching and working in the mining industry. This book
is an essential text for undergraduate and graduate students of
mining engineering and related programs, and a must-have reference
for mining, civil and geotechnical engineers.
In the past 13 years since the publication of Longwall Mining, 2nd
edition in 2006, although there have been no major changes in
longwall mining technology and operations, many incremental
developments in the whole system as well as various subsystems of
the existing longwall mining operational technologies as detailed
in the 2nd edition have been added to this edition. Major
developments are automation, and health and safety technology, as
well as equipment reliability, thereby greatly increasing
productivity and cutting cost. In particular, the longwall system
can now run automatically cut by cut forever without operators'
intervention provided that the geology allows it. Other health and
safety features such as LASC, personal proximity detection, color
lighting, automatic shield water sprays and remote shearer control
are fully operational. There are more than 7000 sensors installed
in current longwall mining systems. The big data obtained and fast
communication technology have been fully utilized to improve and
solve operational problems in real time. Those features are fully
documented in the new edition. In pursuit of high productivity and
cutting cost, life cycle management that increases equipment
reliability has been implemented by OEM. Automation improvement
such as tail-end automatic chain tensioner greatly extends AFC
chain's service life. Other incremental improvements including dust
and methane controls, entry development, panel design and face move
are addressed. Additional operational issues such as extension of
panel width and compatibility test are also discussed. Since the
last plow longwall mine was closed in 2018, the chapter on plow
longwalling has been dropped and in its place Automation of
Longwall Components and System is added. Also, a new chapter
Longwall Top Coal Caving Mining (LTCC) is added due to its
successful application in Australia since 2005. Longwall Mining,
3rd edition will be of interest to professionals and academics in
the field of mining engineering specifically, serving both as a
reference work and an (under)graduate textbook, but will also
interest civil, geomechanical and geological engineers and rock
mechanics professionals, as well as coal operators, mining
consultants, researchers, equipment manufacturers, and government
regulators.
Underground coal mining disturbs both the overburden strata and the
immediate floor strata. The subject of surface subsidence deals
with the issues associated with the movement of overburden strata,
which are the layers from the seam to the surface, where structures
and water resources important to human activities are located.
Surface Subsidence Engineering provides comprehensive coverage of
the major issues associated with surface subsidence. The chapters
are written by experts on surface subsidence in the three leading
coal producing and consuming countries in the world: Australia,
China and the United States. They discuss general features and
terminologies, subsidence prediction, subsidence measurement
techniques, subsidence impact on water bodies, subsidence damage,
mitigation and control, and subsidence on abandoned coal mines. In
addition, the final chapter addresses some of the unique features
of surface subsidence found in Australian coal mines. The book
provides information on coal seams ranging from flat to gently
inclined to steep to ultra-steep seams. Written for mining
engineers, geotechnical engineers and students of mining
engineering, this book covers both theories and practices of
surface subsidence. Unlike previous publications, it also deals
with the subsidence impact on surface and groundwater bodies,
crucial resources that are often neglected by subsidence
researchers.
