        Development


Where does Development need to
be?

What maximum production can we
expect from a single Longwall?


                                 44
            Some Facts

7million tonne Longwall (400m face at
1740 t/m)
 – 2hdg Development       2.88m/hr
 – 3hdg Development       4.51m/hr


10million tonne Longwall
 – 2hdg Development       4.11m/hr
 – 3hdg Development       6.44m/hr

                                        45
          Some Facts

12million tonne Longwall
– 2hdg Development    4.93m/hr
– 3hdg Development    7.73m/hr


15million tonne Longwall
– 2hdg Development    6.17m/hr
– 3hdg Development    9.67m/hr

                                      47
     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.                                   48

          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.
