• A fully automated drilling solution allows the
  operator to monitor drilling operations from a
  safe distance and offers
• Complete automated drilling Operation
• Accurate, precise autonomous machine positioning
  on the design blast hole
• Safety monitoring of the surrounding area for
  obstacles and hazards using HazCam 3D imaging
  system and GeoFencing

46
Why opt for an Autonomous Drill ?For the drill
Operator

• Increased Safety
• Fully autonomous Drill Operation removes the
  driller from the Drill rig Face, to a safe and
  controlled environment.
• Avoids catastrophic disasters caused by Operator
  Fatigue and Negligence.
• Machine productivity is not affected by Human
  Interference ( Shift change Fatigue Break )
• Improved Operator Health condition
• Better Environment for the Operator

47
Why opt for an Autonomous Drill ?For the Key
Decision Makers

• Data Support for Tactical Decision Making
• Real time data collection generates relevant
  reports that arm management with better
  decision-making tools.
• Data generated helps in
• Improved spare parts inventory planning
• Improved Asset Management
• Quicker Troubleshoot Time
• Machine Reliability ( History )

48
Why opt for an Autonomous Drill ?Cost of
Drilling

• Improved Machine Health
• -- The Autonomous package on the Drill Machine
  enables it to look after itself, preventing it
  from loading beyond desired limits.
• Improved RDT life
• The Autonomous package on the Drill machine
  controls the pull down, rotary and torque forces
  within specified limits, giving you an increased
  RDT life.

49
Why opt for an Autonomous Drill ?Improved Hole
Quality and Accuracy

• Improved Hole Pattern Quality
• By eliminating the human induced variance from
  the drilling process, pattern accuracy and hole
  quality increase while re-drills decrease.
• Superior Bench Control
• Automation of the drilling sequence,
  auto-leveling and drilling to exact elevation,
  creates more level benches, resulting in
  operational efficiency
• not depth

REL FLANDERS C750 Autonomous brings regularity to
your hole production equations
One-half inch (12mm) variance out of spec on the
hole radius can cost you plenty in terms of
volume in a 50 blasthole (use your own figures
to modify these typical volume distortions)

Why opt for an Autonomous Drill ?Better
Fragmentation

• The Autonomous system enables the machine to
  drill the blast pattern exactly as designed by
  drastically reducing operator induced variance
  within the pattern and the blast hole itself.
• By introducing increased quality assurance and
  control (QA/QC) into drilling and blasting,
  operations can maintain a higher degree of
  control over fragmentation.
• Improving fragmentation at the mining face will
  result in improved shovel productivity, faster
  loading times, reduced truck cycle-time,
  increased throughput at the crusher and greater
  yield.
