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.
