Changes at Beltana
Back into Mains Driveage
Starting a 2nd Crew
– Self Hired
– Integration of Crews
Change in Development Structure
– Addition to Development Management Team
– Each Crew self sufficient
– Maintain Single Panel Focus.

everything they do.
Whether it be in Motels,
Restaurants, Roadwork's and Coal
Mining.

Development
Place Changing
– Up to 8,200ft / mth = 2,500m / mth
Bolter Miners
– Up to 6000ft / mth = 1830m / mth
FCT Operation Room and Pillar
– Up to 700ft / shift = 210m / Shift
– 21m / hr (Approx 8,500m / mth)
41
3 hdg Development
Opportunities
Design FCT Operation (Consol Loveridge)
– ABM 14’s
– Joy 4 FCT
– Auxiliary Ventilation
To give a 50% improvement in Gate
Road Development.
Process Cost Saving
Up to 9000ft / Month = 2,750m / Month

Where we are at Now
Beltana Bolter Miner
– Joy 12CM12
– 2 Joy 10SC32 Shuttle Cars (16t)
– Breaker Feeder (18t bunker capacity at
1700tphr)
– Auxiliary Ventilation
– 5.5m/hr
Up to 6200ft / mth = 1888m / mth

Development
Where does Development need to
be?
What maximum production can we
expect from a single Longwall?

FCT Model For Beltana
From Data measured at Beltana a Cut Rate
after a belt move of 8.92 m/hr can be
achieved.
Joy FCT Modelled a rate 8.98 m/hr with a Joy
12CM12D.
Therefore we believe an average cut rate
with an FCT for a 100m pillar cycle would be
in the order of 8 to 9m/hr.
This would be a 70% increase in this part of
the Process.

Opportunities
Bolter Miners
– 14ED25 being built in USA to go into
Consol McElroy which commenced
production 1st May 2007.
– ABM 25’s Used throughout QLD and NSW
Automated bolting
Self Drilling Bolt
49
Opportunities
Continuous Haulage Systems
– Joy4FCT
– Stamler Chain Haulage
– Prairie System
– Sandvik Continuous Haulage

Summary
To Advance to the next step in
Longwall Production Development
has to do something different.
By 3 to 5 years time we need to
have developed a new system so
Longwall Coal is not restricted.
52
Development
Can’t keep doing the same and
expect something different.
12 Million Tonne Longwalls being
supported by 500 people.
This is not sustainable.
