  6. Beltana Development • Beltana Update. • Blakefield Update. • USA Systems Study. • Supporting a High Capacity Longwall.

  7. Beltana • Total of 28 Million tonnes mined to date. • Total of 80 km of roadway driveage to date.

  8. Beltana 2007 • Total of 5.5 Million tonnes mined to date. • Total of 16.5 km of roadway driveage to date.

  13. Single or Super • Single Miner v’s Super Unit • Losses • Maint Quality • Standards • Belt Moves / Parallel Tasks • Production Maintenance. • Sustainability

  14. 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.

  15. Single Miner What will it support at Beltana • Development at340m per week • Equates to 144mLWretreat / wk • Equates to 165,600t/ wk • 6.95 Million Tonnes / yr

  16. Strategies • Key Points to our Strategies • Manning. • Standards. • Measurement. • Continuous Improvement. • Fit for purpose equipment. • Communication.

  17. Blakefield South • 173km of Driveage • 44.6 million ROM tonnes • 400m Longwall Face • 6.7 million Tonnes / Year • 9 year Life

  18. Blakefield South • Up to 10m3/t if insitu CH4 • High volumetric capacity ventilation system maximum 580m3/sec. • Force–exhaust (pressure balanced) ventilation system. • 7 heading mains / 3 heading gate roads.

  21. USA System Study • Review Strategies for future Development systems. • Review 3 Hdg Gate Road Development. • Review Continuous Haulage. • New Technology.

  22. Mines Visited • Peabody Highland • FCT in Room and Pillar Operation. (High Voltage Miners.) • Consol Loveridge • 3 Hdg Development and changing from batch Haulage to FCT. (ABM’s.) • Cumberland • 3 Hdg Development. (Miner Bolters and Mobile Bolters.)

  23. Mines Visited • Twenty Mile • 3 Hdg Development (Place Changing.) • High Producing Mine. • San Juan • 3 Hdg Development (place Changing.) • Good Technology. • Joy Franklin • New Technology ED miners, Automatic Drill Rigs and FCT’s.

  24. San Juan Transport

  25. Specialise • The Americans Specialise everything they do. • Whether it be in Motels, Restaurants, Roadwork's and Coal Mining.

  26. 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)

  27. 3 hdg DevelopmentOpportunities • 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

  28. 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

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

  30. 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

  31. 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

  32. Low Hanging Fruit Obtained • Process Improvement Old 7.2Day Pillar Cycle New 3.6 Day Pillar Cycle • Total Process Improvement 100 %

  33. 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 rate8.98m/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.

  34. 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

  35. Opportunities • Continuous Haulage Systems • Joy4FCT • Stamler Chain Haulage • Prairie System • Sandvik Continuous Haulage

  36. FCT Stats

  37. 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.

  38. Development • Can’t keep doing the same and expect something different. • 12 Million Tonne Longwalls being supported by 500 people. • This is not sustainable.

  39. USA is BIG
