Single or Super Single Miner v’s Super Unit Losses – Maint Quality – Standards – Belt Moves / Parallel Tasks – Production Maintenance. – Sustainability 28

Changes at Beltana Back into Mains Driveage Starting a 2 nd Crew – Self Hired – Integration of Crews Change in Development Structure – Addition to Development Management Team – Each Crew self sufficient – Maintain Single Panel Focus. 29

Single Miner What will it support at Beltana Development at 340 m per week Equates to 144 m LW retreat / wk Equates to 165, 600 t / wk 6. 95 Million Tonnes / yr 30

Strategies Key Points to our Strategies – Manning. – Standards. – Measurement. – Continuous Improvement. – Fit for purpose equipment. – Communication. 31

USA System Study Review Strategies for future Development systems. – Review 3 Hdg Gate Road Development. – Review Continuous Haulage. – New Technology. 36

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. ) 37

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. 38

San Juan Transport 39

Specialise The Americans Specialise everything they do. Whether it be in Motels, Restaurants, Roadwork's and Coal Mining. 40

Development Place Changing – Up to 8, 200 ft / mth = 2, 500 m / mth Bolter Miners – Up to 6000 ft / mth = 1830 m / mth FCT Operation Room and Pillar – Up to 700 ft / shift = 210 m / Shift – 21 m / hr (Approx 8, 500 m / 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 9000 ft / Month = 2, 750 m / Month 42

Where we are at Now Beltana Bolter Miner – Joy 12 CM 12 – 2 Joy 10 SC 32 Shuttle Cars (16 t) – Breaker Feeder (18 t bunker capacity at 1700 tphr) – Auxiliary Ventilation – 5. 5 m/hr Up to 6200 ft / mth = 1888 m / mth 43

Development Where does Development need to be? What maximum production can we expect from a single Longwall? 44

Some Facts 7 million tonne Longwall (400 m face at 1740 t/m) – 2 hdg Development – 3 hdg Development 2. 88 m/hr 4. 51 m/hr 10 million tonne Longwall – 2 hdg Development – 3 hdg Development 4. 11 m/hr 6. 44 m/hr 45

Some Facts 12 million tonne Longwall – 2 hdg Development – 3 hdg Development 4. 93 m/hr 7. 73 m/hr 15 million tonne Longwall – 2 hdg Development – 3 hdg Development 6. 17 m/hr 9. 67 m/hr 46

Low Hanging Fruit Obtained Process Improvement Old 7. 2 Day Pillar Cycle New 3. 6 Day Pillar Cycle Total Process Improvement 100 % 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 12 CM 12 D. Therefore we believe an average cut rate with an FCT for a 100 m pillar cycle would be in the order of 8 to 9 m/hr. This would be a 70% increase in this part of the Process. 48

Opportunities Bolter Miners – 14 ED 25 being built in USA to go into Consol Mc. Elroy which commenced production 1 st May 2007. – ABM 25’s Used throughout QLD and NSW Automated bolting Self Drilling Bolt 49

Opportunities Continuous Haulage Systems – Joy 4 FCT – Stamler Chain Haulage – Prairie System – Sandvik Continuous Haulage 50

FCT Stats 51

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. 53

USA is BIG 54
