LASC 1.0 – what has worked well
• Shearer Position Measurement System (SPMS)
hardware – high-performance inertial navigation
• Face alignment – broad uptake with significant
impact.
Overview | |Challenges Enabling Technologies | Solution | Looking to the Future
• High-quality onboard shearer attitude/horizon
information available to the OEM shearer controller
• Has delivered a process control approach to shearer
automation which of itself has produced benefits
LASC 1.0 – where are the main gaps
• Creep/retreat – an old chestnut that still needs some
cracking
• Horizon control that has general applicability. LASC 1.0
has provided a solid platform but not the full solution
Overview | |Challenges Enabling Technologies | Solution | Looking to the Future
• Need for active seam tracking for improved horizon
control
• LASC software/system configuration and management
tools too complicated
LASC 1.5 – what have we been working on
• Major rewrite of LASC server software • Simplified installation, commissioning and configuration
• Consolidate and reduce the number of software modules to reduce
complexity
• Support for a range of databases (not just MySQL) via ODBC interface
• Improved operator screens including database interface .
Overview | |Challenges Enabling Technologies | Solution | Looking to the Future
• ITAR-free Inertial Navigation System• LASC support for non-ITAR inertial navigation hardware
• Non-ITAR INS has been successfully trialled in Australia. This INS can be
exported to ITAR-restricted countries.
• Made available to the industry via the LASC longwall OEMs
LASC 2.0 – where to next
• The Mining Technology Research Group continues to undertake
strategic research into new LASC-related technologies
• We are actively seeking feedback from those in the industry
with LASC experience to chart a course for next generation
LASC developments
• Learnings from LASC1.0 experience
Overview | |Challenges Enabling Technologies | Solution | Looking to the Future
• Learnings from LASC1.0 experience
• Review and input into the CSIRO 2, 5 & 10 year technology
development roadmap

LASC 2.0 – some specific technologies
• Active seam tracking• Optical and thermal marker band
• CSIRO interest is in image/data processing and LASC integration
• System simplification• Onboard shearer (SPMS) data processing
• Remove surface database and services from control loop
• Simplify installation, commissioning and configuration
Overview | |Challenges Enabling Technologies | Solution | Looking to the Future
• Simplify installation, commissioning and configuration
• Real time FA and HC data• Reduce LASC response cycle times (presently up to 3 shear cycles)
• Creep/retreat (and more)• New scanning laser technology
• CSIRO-developed transparent panoramic flameproof enclosure (current
ACARP project - provisional patent)
• Laser/enclosure has broader applicability
3D scanning laser – panoramic flameproof enclosureFor longwall creep/retreat measurement and more

CM Guidance project update
• Current ACARP project
• Began in 2009
• Performance has been verified in extensive above
ground testing
• Using field-realistic experimental set up
Overview | |Challenges Enabling Technologies | Solution | Looking to the Future
• Underground guidance equipment package audit
complete
• Single package in standard enclosure
• Guidance package ready for installation on CM
• Scheduled for installation in November.
• Sandvik machine in NSW
Solution: Test Platform – The Phoenix

CM Guidance performance
• Performance
• 30cm maximum cross track error over 2.7km, 2.5hr “two heading
roadway” mission – repeated experiments at Ebenezer test site
• Communications
• An open-system data communications specification has been developed
to ensure interoperability across multi-vendor mining equipment

Overview | |Challenges Enabling Technologies | Solution | Looking to the Future
CM Guidance project update
• Current underground testing will proceed with
guidance system in “monitoring only” mode • Instantaneous pointing and tilt information can be made available
via on-machine graphical display
• Logged data will be compared mine survey information over an
expended period to establish confidence and performance measure
Overview | |Challenges Enabling Technologies | Solution | Looking to the Future
• Subsequently data can be made available to the
miner controller for steering control
• Required OEM development and cooperation
• Final stage to close the control loop on full navigation • Automated roadway alignment (and cut-throughs etc)
