Wambo Operation
● Wambo Mine complex is located in the Hunter Valley of New
South Wales, Australia.
● The mine is 14kms from Mount Thorley on the Golden Highway
at Warkworth. Wambo consists of an underground mine, open
cut mine, and CHPP.
● All areas work as a seven day operation.
● North Wambo Underground is a new longwall mine which
commenced development on 14 November 2005 under Excel
Coal ownership and continues under Peabody Energy Australia
ownership.
● The mine’s longwall is currently extracting Longwall block 7.

North Wambo Overview
15
NWU – Multi Seam Experience
● No significant strata issues either above or bellow workings. However we do put additional support into areas of goaf edges.
● Harder and slower cutting where there are no goaf influences.
● Have encountered many through seam boreholes. Only 1 has caused problems with water flowing up from below.
● No gas inflows.
● No water inflows however it is a consent condition to drain overlying workings. We have been delayed draining workings.

Seam Height
● The Wambo seam may vary between 1.8m and 2.4m in height.
Seam Grade
● The Wambo seam grade this block is 1 in 20 length of block and cross grade is 1 in 90 at the start and changes to 1 in 30 at about the 1500m mark.
Extraction Height
● The extraction height on the LW face will vary from 2.7m to 2.2m in height.
Performance
● Mine designed for 2.5 MTPA. Doing 5.4MTPA.
● Target 115m per week in most conditions.

Longwall 6 Recovery
21
• Bolt up 9.5 Days
• LW6 to 7 move 21 days
• 7 days negative float
• No injuries
• Ramp up to full production in
about 2 weeks
Operating discipline
● Plan for maintenance, stick to plan
● Ensure that equipment overhauled to best
standard at start of block
● Secondary support etc. are installed on MG side
– Once going there are no delays
● 2 x Everything except shields
– Maintenance can be done offline and some rebuilds
done on site
– Good commissioning of electrical components
22
Mechanical Innovation
● Extremely simple face only 6 solenoids per shield
● No shield sprays. Keep people out of dust.
● Pilot pressure on solenoids. – Improves reliability.
● Electro hydraulic boot end (safer and reduces hosing).
● Dump valve relocation for faster response.
● Modification of BE to surf across poor floor.
● Life cycle analysis of hosing to minimise failure.
● Galvanised chain.
23
Dump Valve
24
Electrical Innovation
● Custom wiring looms for LW installation.
● Web cams inside enclosures.
● TG drive modifications to reduce wiring.
● LED lights.
25
26
Mining Innovation
● MBR ventilation.
● TG horizon line.
● Rigid monorail and airtrack.
● TG dusting down pipeline.
● CH4 / BSL interlock.
● Belt downtime reduction.
– NDT testing of rollers.
– Systematic testing of belt switches.
27
Longwall Face: Ventilation
● Low gas in-seam but higher
gas in surrounding strata.
● Workings above complicate
post drainage.
● Long panels 3.4km.
● Low Longwall face (2.2m).
Medium roadways (2.7m).
● Gate roads stand in goaf.
● Air goes to back of goaf
with seam gradient.
● Seal deterioration caused
interconnection LW1 - LW2.
● Rider seams have oxidation
potential (Spon Com risk). 28

Air track for Transporting belt structure
● Increased production due to less time handling structure.
● Men able to resume production whilst 2 people unload
structure at next CT.
● Less injuries associated with the air track .
30
Pantech relocation
● 2 transformers and 2 pump stations (Pantech).
● Power up next Pantech prior to move (Leapfrog).
● This means that only the services monorail has to be
moved forward when window is reached.
● This enables Pantech moves to be done in 1.5 – 2Hrs.
● Maintenance is done off line.
31
Automation
● LASC
– Auto straightening removes personnel from dust.
– Eliminates shiftly straighteners.
– Adds about 5 – 10 metres retreat per week.
● Advanced shearer automation
– Shearer Gate automation.
– Incremental Horizon control.
– Most problems occur in manual control.
– Have shearer operate in auto with minimal amount of manual
over ride.

LASC

Shearer Gate End Automation
● Automation adjusts cowls.
● Drum positions.
● Speed changes.
● Direction changes (waits for shield advance).
● Takes approximately 1 minute per shear less.

Auto Gate Cut Out

Manual Shearer Gate End cut on average took 14 minutes and 22 seconds from RS23 (PL2) to RS23

Future Upgrades
● CME initiated wedge cuts.
● Integrated power management.
– BSL, AFC, TX, conveyor optimisation.
– Allow shearer speed to be adjusted at each part of shear.
● CH4 spike minimisation via shearer speed control.
– Slowing down at shield 115 when gas is already high to minimise
total delays.
● Anti collision.
– Change in pan angles and shields not in correct positions more
likely to cause collisions.
