  4. SandvikDevelopment Systems • Introduction – Sandvik • Where we have come from • Where we are now (and what has driven the changes) • Where is our future ~ 2012 (5 years) • New Products

  5. Where We Have Come From • 1st simultaneous cut and bolt machine (commercially available) • Capable of achieving high “one off” performance results, not been sustainable – over longer term Why? • Ergonomics • Complex engineering & maintenance • Not able to measure development system/process constraints (pillar design, matched equipment, service support etc)

  6. Where Are We Now - Ergonomics • Platforms are larger, level,clear and open • Bolter station positions and push button controls • Operator screen locations • Non slip and anti vibration floor mats (reduce fatigue/vibration) • Adjustable height platforms (reduced repetitive strain) • Access / egress (fold up rear steps, 3 point contact) • Machine lighting – (to illuminate walkways, ladders, controls, work areas) • North / South roof rigs (reduces twisting during bolting)

  7. Where Are We Now - Ergonomics • Integrated mesh carrier(reduduces manual handling) • Housekeeping (materials/consumables stored to suit ergonomic & open work area philosophy) • +100% increase in ventilation duct area • “Outrigger” design supports flexible duct and minimises twisting (maintains vent duct area) • Hydraulic driven air fans provide evaporative cooling in a humid environment(prevents safety glasses from fogging up and assists with dust control) • Flexible ducting “connect/reconnect” designed for single man operation(for changing material pods if required)

  8. Where Are We Now – Engineering/Maintenance • Hose and cable management(manifolds, exterior routing) • Recirculating oil filtration(eliminates high pressure filters) • 24V flameproof solenoids • Simplified hydraulics/reduced complexity - fully load sensing and single in line pumps • 2 speed drill motors – lower pump flow requirements • 6 rig simultaneous operation • Fully load sensed hydraulics (including bolters) = lower operating temperatures(from 60 deg - < 40 deg)

  9. Where Are We Now – Measuring the Process

  10. Uptime versus Downtime But what happens in the ‘uptime’….

  11. There is the need to compare these results with what can be realistically achieved….

  12. Theory vs reality, but how is it monitored?....

  13. ABM 20_010 Cyclereport from 2003/05/07 Shift 3: Cycle Time [min] Cutting Activity Bolter Activity Conveyor Activity Cycles longer than the planned 11 minute cycle time. These cycles require a more detailed investigation from a process control perspective. The remaining cycles have achieved 11 minutes or less. 30 • Manage by exceptions 24 20 16 Average 12 8 4 0 0h 1 h 2 h 3 h 4 h 5 h 6 h 7 h 8 h

  14. ABM 25_015 Cyclereport from 2004/06/17 Shift 2: Cycle Time Cutting Activity At this point, if it was a 2 shuttle car cycle, the cycle time achieved would have been 10 minutes or less. Due to requirement for 3rd shuttle car, cycle times of 16 minutes achieved. [min] Bolter Activity Conveyor Activity 30 24 Average 20 16 12 8 4 0 0h 1 h 2 h 3 h 4 h 5 h 6 h 7 h 8 h • ~ 50% increase in cycle time from a 2 car cycle to a 3 car cycle

  15. Sequential roof and rib bolting Rib bolting (generally) takes longer

  16. Macro View • Performance expectations should be variable and based on conditions, position in pillar cycle etc, not averaged over an entire gate road • Performance expectations can be based on actual history

  17. Where is our Future ~ 2012 Focus on development system solutions • Ergonomics – improved ergonomics leads to safer and more productive development (continue drive towards zero harm) • Engineering/Maintenance (continue drive towards 100% reliability) • Measuring the development system/process performance • Towards Automation • New Products

  18. Measuring the development system/process performance • Live production reports (on machine & surface) (maintain a consistent “sense of urgency”) • Roof mapping (real time and panel duration) • Longer term trending of operational data (weekly, monthly, pillar etc) • Longer term trending of predictive maintenance data • Playback in 3D (all functions monitored) • Equipment monitoring /reporting => management tool to improve development performance • It wont change anything by itself – it does enable the right questions to be asked (and provides interested people with a more accurate understanding of the development process)

  19. Towards Automation • Electronic Push Button Drill Rig Control • greater control and flexibility over the drilling and bolting process, • software controlled (not reliant on hydraulic logic) • Consistent bolt set times and guaranteed minimum bolt torque • Easily adaptable for any self drilling bolts • Future technology developments will make units smaller • Horizon control /Auto Cut • possible interface with new & existing (coal seam/rock, in-seam stone bands etc) technologies (gamma, CID, infra red etc) • Auto Cut – simple/easy to use/flexible (get the basics right first) • Interface with materials/services systems • Material pod changeout systems (including continuous haulage systems) • Monorail systems (ventilation, complete) • Integration with other Sandvik product line technologies • Drilling / bolting / systems • Cable bolt feed systems etc • Potential interface with other development process management systems • Self drilling bolt (Steve Weaver)

  20. New Products – EBS 120 Punch Mining System • Continuous Haulage System • Utlises an ABM10 with mobile hopper car and LTU system (~200m punches) • Currently in operation in USA • Designed capacity > 10 metres/operational hour

  21. Sub-Main Advances as needed. Panels develop from Return Side Extraction Sequence

  22. New Products – CHS 500 – SICON Conveyor • Continuous Haulage System • ~ 220m length (500m3/hr) • Currently being built in USA
