4. Sandvik Development 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 Why?
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?....

Cycle Time
[min]
Cutting Activity
Bolter 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.

14. ABM 25_015 Cyclereport from 2004/06/17 Shift 2:
Cycle Time
Cutting Activity
[min]
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.

~ 50% increase in cycle time from a 2 car cycle to a 3 car cycle

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

17. 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

18. 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

19. 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)

20. 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)
